Software Writing for Timer and DebuggingIntroductionThis lab guides you through the process of writing a software application that utilizes the private timer of the CPU. You will refer to the timer’s API in t he SDK to create and debug the software application. The application you will develop will monitor the dip switch values and increment a count on the LEDs. The application will exit when the center push button is pressed.ObjectivesAfter completing this lab, you will be able to:∙ Utilize the CPU’s private timer in polled mode∙ Use SDK Debugger to set break points and view the content of variables and memoryProcedureThis lab is separated into steps that consist of general overview statements that provide information on the detailed instructions that follow. Follow these detailed instructions to progress through the lab. This lab comprises 4 primary steps: Open the project in Vivado, create a SDK software project, verify operation in hardware, and launch the debugger and debug the design.Design DescriptionYou will use the hardware design created in lab 4 to use CPU’s private timer (see Figure 1). You will develop the code to use it.Figure 1.

Monitor memory location4-1-10.Enter the address for the private counter load register (0xF8F00600), and click OK.Figure 10. Monitoring a Memory AddressYou can find the address by looking at the xparameters.h file entry to get the base address(), and find the load offset double-clicking on the xscutimer.h in the outline window followed by double-clicking on the xscutimer_hw.h and then selectingXSCUTIMER_LOAD_OFFSET.Figure 71. Memory Offset4-1-11.Click on the Step Over button to execute one statement which will load the timer register.Notice that the address 0xF8F00604 has become red colored as the content has changed. Verify that the content is same as the value: dip_check_prev*325000000. Y ou will see hexadecimalequivalent (displaying bytes in the order 0 -> 3).E.g. for dip_check_prev = 1; the value is 0x13D92D40; (reversed: 0x402DD913)4-1-12.Click on the Resume button to continue execution of the program. It will stop at the writing to the LED port (skipping fourth breakpoint as center push button as has not occurred).Notice that the value of the counter register is changed from the previous one as the timer wasstarted and the countdown had begun.4-1-13.Click on the Step Over button to execute one statement which will write to the LED port and which should turn OFF the LEDs as the count=0.4-1-14.Double-click on the fifth breakpoint, the one that writes to the LED port, so the program can execute freely.4-1-15.Click on the Resume button to continue execution of the program. This time it will continuously run the program changing LED lit pattern at the switch setting rate.4-1-16.Flip the switches to change the delay and observe the effect.4-1-17.Press center push button and observe that the program suspends at the fourth breakpoint. The timer register content as well as the control register (offset 0x08) is red as the counter value had changed and the control register value changed due to timer stop function call. (In the Memorymonitor, you may need to right click on the address that is being monitored and click Reset torefresh the memory view.)4-1-18.Terminate the session by clicking on the Terminate () button.4-1-19.Exit the SDK and Vivado.4-1-20.Power OFF the board.ConclusionThis lab led you through d eveloping software that utilized CPU’s private timer. You studied the API documentation, used the appropriate function calls and achieved the desired functionality. You verified the functionality in hardware. Additionally, you used the SDK debugger to view the content of variables and memory, and stepped through various part of the code.。

Its space-saving design eases installation directly on the bench top. The device is easy and convenient to operate.Before using the Concentrator 5301 for the ﬁrst time, please read the manual. The latest version of the manual and the safety instructions in your language can be found on the Internet at .The device must not be operated in a hazardous or ﬂammable environment and must not be used to evaporate/centrifuge self-inﬂammable substances.Before plugging in the device, compare your power supply with the electrical requirements listed on the identiﬁcation plate (see Fig. 1 and 2 on the fold-back cover at the front of this manual: identiﬁcation plates on the right-hand panel of the Concentrator 5301 Complete System and on the rear panel of the Concentrator 5301).The rotor must be properly mounted. It should be loaded symmetrically.Repairs must only be performed by an Eppendorf authorized service technician. Only use original rotors and spare parts recommended by Eppendorf.Do not expose body parts to the vacuum under any circumstances.Continuous pumping of liquids is not permitted.Please note the maximum permissible pressures and pressure differences listed under "Technical Data". Excesspressure in the pipes caused by closed taps or blocked pipes can result in bursting. Therefore, be sure to always keep the exhaust fumes pipe free and to use sufﬁciently wide pipes.When evaporating poisonous liquids or liquids which contain pathogenic bacteria, a suitable chemical or cooling trap must be used to ensure the required condensation and separation of the vapor. The corresponding safety precautions must be observed (hood, lab with appropriate safety class).Please avoid releasing poisonous, health-damaging or corrosive substances. When handling poisonous, health-damaging or corrosive substances or pathogenic germs of risk group II (see World Health Organization: "Laboratory Biosafety Manual"), the appropriate national regulations are to be observed.Before evaporating, all the tubes should be subjected to a visual inspection for material damage. Damaged tubes must not be centrifuged, as if tubes break, there may be further damage to the Concentrator and its accessories in addition to loss of the sample.1.1 Safety precautionsIntroduction 118Declaration concerning the ATEX directive (94/9/EC)The present design and ambient conditions inside Eppendorf centrifuges mean that they are not suitable for use in a potentially explosive atmosphere. The centrifuges must therefore only be used in a safe environment such as the open environment of a ventilated laboratory or a fully-extracted fume hood. The use of substances which may contribute to a potentially explosive atmosphere is not permitted. The ﬁnal decision on the risks in connection with the use of such substances is the responsibility of the user of the centrifuge.TransferIf the device is passed on to someone else, please include the instruction manual.Disposal In case the product is to be disposed of, the relevant legal regulations are to be rmation on the disposal of electrical and electronic devices in the European Community The disposal of electrical devices is regulated within the European Community by nationalregulations based on EU Directive 2002/96/EC on waste electrical and electronic equipment (WEEE).According to these regulations, any devices supplied after 13.08.05 in the business-to-business sphere, to which this product is assigned, may no longer be disposed of in municipal or domestic waste. They are marked with the following symbol to indicate this.As disposal regulations within the EU may vary from country to country, please contact your supplier if necessary.I n t r o d u c t i o n 119Concentrator 5301 Complete System: After unpacking the device, unscrew the two thumbscrews at the rear of the base plate (transport safety device of the vacuum pump).Place the device onto a level, horizontal surface. To ensure sufﬁcient ventilation, there should be 10 cm clearance at both sides of the device and 30 cm at the back of the device.Connect the emission condensator to the nozzle on the left side of the pump housing (see Fig. 3 on the fold-back cover at the front of this manual) using the solvent-resistant tube included in the accessories (8 mm inner diameter).Connect the device with the power cable to the main power supply. The main power socket is on the bottom right of the housing of the vacuum pump next to the main power switch. When the device is switched on, the lid can be opened as long as the control lamp Lid lights up.Before commissioning the Concentrator with integrated vacuum pump, please be sure that the ambient temperature during operation is between 15 °C and a maximum of 35 °C. Measures according to DIN VDE 0530 are to be taken when setting up the device at an elevation greater than 1,000 m above sea level.Concentrator 5301: As for Concentrator Complete System, however, the removal of the transport safety device for the vacuum pump is not applicable.The main power switch on the rear panel of the device is next to the socket for direct connection of a vacuum pump (see Fig. 2 on the fold-back cover at the front of this manual).A vacuum pump can be connected to the main power supply via the Concentrator with a special connector (see Sec. 7, Ordering information).The power consumption of a vacuum pump which is connected directly to the Concentrator is max. 400 W.The normal program sequence can also be performed with a vacuum pump connected to the power supply indepen-dently of the Concentrator or with a central vacuum system when a solenoid valve is switched between the vacuum pump and the Concentrator. For additional information, please contact an Eppendorf service technician.If a solenoid valve is not used, the vacuum system can be disconnected from the Concentrator as required before the evaporation run is ended by manually closing a correctly positioned valve (e.g., cock with ground-in stopper).Every pump used should be able to hold a maximum ultimate pressure of 20 mbar.Condensate separator: Depending on the type of pump used, an emission condensator can be switched between the devices or behind the pump. The solvent-resistant pump of the Concentrator Complete System enables installation of the emission condensator behind the pump.Note: When attaching a ﬁlter to the outlet of the condensator, the excess pressure at the pump outlet of the Concen-trator Complete System must not exceed 1 bar.When evaporating chemically aggressive liquids or liquids with volatile, chemically aggressive or biologically hazardous components, an appropriately effective cooling trap or chemical trap must be used instead of a condensate separator.Concentrator 5301 complete system with gel dryer connection (Order no. 5301 000.326): In order to be able to connect a gel dryer to the Concentrator 5301, please use the accompanying tube connection. Screw the tubeconnection into the free thread of the stop valve on the left side of the Concentrator. The size of the connection thread for the gel dryer connection is G1/4".1 Concentrator 5301 / Concentrator 5301 Complete System /Concentrator 5301 complete system with gel dryer connection without rotor1 Rotor F 45-48-11 with 6 feet for rotors F 45-48-11 and F 45-72-81Main power cable 1Instruction manual for Concentrator / Concentrator 5301 Complete System 1Emission condensator (only for Concentrator Complete System)1Tube for connecting the emission condensator / Concentrator Complete System 1Set of main power fuses 1.2 Installing the device1.3 Delivery packageIntroduction121Mount the rotor onto the drive axle making sure it is seated onto the spindle. To dismount, pull rotor off the drive axle. The rotor does not have to be tightened.A spacer is available (order no. 5301 316.005) for sandwich use of 2 rotors (with rotors F 45-48-11 and F 45-72-8 in any order, not with rotor F 45-70-11).The delivery package of the device contains feet which can be screwed into the appropriate bores of the rotorsF 45-48-11 and F 45-72-11. The feet make sure that the tubes are not pushed out of the bores when the rotor is placed onto the bench.The rotor should be loaded symmetrically with open tubes. Maximum unsymmetrical load for one run ≤ 1 hour: difference of 6 x 2.0 ml tubes between 2 rotor sides.The temperature selected can be changed during the run and is regulated accordingly. After switch-on, the device is set to operation without heating.Following evaporation, ensure that heating is switched off again. To do so, press Set temp repeatedly until the three temperature displays go out.Note: When heating selected, the behavior of the samples at the desired temperature must be compatible.Caution:Avoid touching the wall of the rotor chamber after evaporation at 60 ˚C. This could have a temperature in excess of 65 °C.When switching from a higher to a lower temperature, a rapid blinking of the control lamp after a brief waiting period shows that the rotor chamber temperature deviates from the selected temperature.Close the lid.Press Start :The rotor starts up. The Rotation control lamp lights up (green). As soon as the lid haslocked automatically, the Lid control lamp (green) goes out.At 1,000 rpm, the vacuum pump is switched on. The Vacuum control lamp lights up andthe ventilation valve closes. The Ventilation control lamp ﬂashes.The rotor accelerates to its ﬁnal speed of 1,400 rpm.If Start is pressed during the run, the ventilation valve is opened, air streams in andrinses the pump and the tubing system.We recommend that you press Start for a few seconds at the end of the last run of theday (see Sec. 3.3) to remove remaining condensate from the pump.Press Stop :The rotor chamber is ventilated. After 2 s, the vacuum pump is switched off.The Vacuum control lamp goes out.The rotor decelerates without braking (see Sec. 3.5).When the rotor is at a standstill: The Rotation control lamp goes out.The Lid control lamp lights up when the lid can be opened.Press Set temp :30 ˚C display ﬂashes until the temperature in the rotor chamber is reached(30 ˚C display constant).If Set temp is pressed repeatedly, the display switches to 45 ˚C , then to 60 ˚C andthen the heating is switched off.3.1 Mounting / Dismounting the rotor3.2 Loading the rotor3.3 Evaporation without heating3.4 Evaporation with heating3 OperationOperation322To switch on gentle braking, press Brake . The Brake control lamp lights up (red).It is possible to switch over between deceleration with soft braking/without braking at any time.For optimal evaporation of samples, 3 different functions are available:Function 1:This function is especially suitable for the evaporation of alcoholic solutions and is set as a default when the device is switched on.Function 2:For evaporation of solvents with a particularly high vapor pressure.Function 3:This function is especially suitable for the evaporation of aqueous solutions.These functions are switched on by pressing Brake and Set temp simultaneously. To indicate that the device has recognized that these two keys have been pressed, the control lamp Ventilation ﬂashes brieﬂy three times. When both keys are pressed, the different functions are selected in succession.When the device is at a standstill or in operation, the function selected is indicated as follows by the control lamps Ventilation and Vacuum :Desiccator function:The Concentrator 5301 can also be operated as a desiccator only. The rotor chamber is evacuated normally, although the rotor does not move.This function can be called up and ended as follows:–Hold down the STOP key. After one second, press START as well. The run is carried out with the set parameters (F1, F2, F3, selected temperature) without the rotor moving. Function 2 is recommended for this.–Press the STOP key to end the desiccator function.In the event of a power failure, the ventilation valve opens. Before the rotor comes to a standstill, standard pressure is restored in the rotor chamber. The lid can be unlocked when the rotor is at a standstill by inserting a sharp object (paper clip) into the opening in the right panel of the housing under the lid. The lid can then be opened.The fuses are located under the ﬂap in the housing of the main power switch.The Concentrator 5301 complete system is available under the order no. 5301 000.326 with gel dryer connection. The gel dryer can be operated parallel to the evaporation or on its own. When using parallel to the evaporation, the stop valve is opened, meaning that the knob is parallel to the ﬂow direction.The drying of the gel and the evaporation begin with the switching on of the internal vacuum pump.If simultaneous evaporation is not desired, please use the Exsiccator function (see Ch. 3.6).Before the device is started, the enclosed tube connector must be screwed into the stop valve.Please close the stop valve when the gel dryer is no longer required.Ventilation control lampVacuum control lamp Function 1during run in standstill ﬂashes ﬂasheslights up constantly offFunction 2during run in standstill offlights up constantly lights up constantly off Function 3during run in standstillofflights up constantlyﬂashes ﬂashes3.5 Centrifugation with braked deceleration3.6 Special functions3.7 Opening the device in the case of a power failure3.8 Exchanging the main power fuse3.9 Gel dryer connectionO p e r a t i o n3 Operation323When cleaning and disinfecting the device on the outside and inside (rotor chamber), only use neutral detergents (e.g. Extran ® neutral) and disinfectants containing alcohol. Disconnect the main power plug before starting cleaning.For the frequent evaporation of corrosive liquids (e.g. buffers containing HCl), apply a thin coating of Vaseline to the rotor and rotor chamber (see "Ordering information").The rotors can be autoclaved at 121 ˚C for 20 minutes. They can be cleaned with the same solutions as the device. Do not allow saline aqueous solutions to dry. Do not allow acids or alkaline solutions to soak into the material (aluminum).The chemical-resistant pump of the Concentrator 5301 Complete System does not require maintenance. The pump and tubing system can be blown through by pressing Start during the run (see Sec. 3.3).Valves and diaphragms are subject to natural wear and should be renewed by an authorized Service technician, at the latest when the pressure values begin to decrease. A permanent conveyance of liquids can damage diaphragms and valves. Please regularly remove the condensation from the pump as described above. This measure prolongs the service life of the parts subject to wear and tear.Glass breakageWhen concentrating from glass tubes, be aware that the risk of glass breakage increases during centrifugation. Please observe manufacturers’ information about maximum loading of centrifuge tubes.In case of glass breakage, carefully remove all splinters from the rotor and the centrifugal chamber immediately.Otherwise ﬁne glass splinters will scratch the surface of the rotors, reducing their resistance to chemicals. Air vortices will result in very ﬁne black abraded metal in the centrifugal chamber; in addition to damaging the centrifugal chamber and rotor, this material will also cause samples to become contaminated.Returning devicesWhen returning the Concentrator 5301, please ensure that the device is completely decontaminated so it does not present any kind of health hazard to our Service staff.You will ﬁnd additional information and a blank of the decontamination conﬁrmation at . Do also consult your laboratory safety ofﬁcer about a suitable decontamination method.Please ﬁll out the decontamination conﬁrmation and place it together with the device when it is to be sent back to Eppendorf.4 Cleaning and maintenanceCleaning and maintenance424If the suggested measure repeatedly fails to eliminate the fault, please contact Service.Error CauseSolutionNo display.No main power connection.Power failure.Check power supply cable.Check main power fuse at the device (see Sec. 3.8) and in the laboratory.Concentrator does not start up (Display "Lid" ﬂashes).Lid not closed.Lid switch defective.Close lid.⇒ SERVICE.Concentrator does not start up or switches off during run(Rotation control lamp ﬂashes.)Mechanical stiffness.Electronics error in drive.Move rotor by hand.Remove any obstruction and restart.⇒ SERVICE.No noticeable evaporation.Sealing ring in lid of device damaged.Mount new sealing ring(see "Ordering information").All 3 temperature displays ﬂash.Heating or temperature sensor defective.⇒ SERVICE.All displays ﬂash.Electronics error.⇒ SERVICE.Pump does not start up.Thermal switch atconnecting box of pump initiated.Pump overload,leave to cool, restart.⇒ SERVICE.One of the heating displays ﬂashes (1x per second).Heating at least 5 °C above nominal value.Allow heat from previous run to cool.One of the heating displays ﬂashes rapidly (2x per second).Heating at least 10 °C above nominal value.Switch off external heat source (e.g. halogen lamp).No conveyance capacity.Long, narrow pipe?Condensation in the pump?Use short pipes that are wide enough.Allow pump to run for a few minutes with the intake connector open.T r o u b l e s h o o t i n g t a b l e5 Troubleshooting table5Power supply:see identiﬁcation platePower consumption: max. 500 W(with largest external pump permitted) Max. rotational speed:1,400 rpmMax. centrifugal force:240 x gMax. load:96 x 2.0 ml micro test tubesMax. density of material to be centrifuged: 1.2 g/mlPermitted ambient temperaturefor operating the device:15–35 °CPermitted max. average annual relative air humidity:75 %Dimensions (H x W x D)Concentrator 5301:230 x 320 x 369 mm Concentrator 5301 Complete System:298 x 320 x 530 mm WeightConcentrator 5301:17 kgConcentrator 5301 Complete System:31 kgMain power fuse 230 V: 4.0 A time-lagMain power fuse 115 V: 6.25 A time-lagMax. excess pressure at pump outlet ofConcentrator 5301 Complete System: 1 barTechnical data of the diaphragm vacuum pumpMax. power / motor capacity of the diaphragm vacuum pump120 V 2.9 A / 220 W230 V 1.6 A / 220 WMax. power input of the diaphragm vacuum pump120 V350 VA230 V345 VAMotor protection Thermal cutout Protection degree according to IEC 529IP 54Maximum output 50 / 60 Hz 1.7 / 2.0 m3/hAttainable ultimate pressure (absolute)9 mbarMaximum permissible pressure at outlet (absolute) 2 barMaximum pressure difference between inlet and outlet 2 barNominal rotational speed of the pump at 50 / 60 Hz1500 min-1 / 1800 min-1 Materials of the diaphragm vacuum pump surfaces coming into contact with media Housing cover insert PTFE carbon reinforced Head cover, diaphragm clamping disc,inlet / outlet / ﬁttings ETFEValve FFKMDiaphragm PTFE-NBRHose PTFETechnical speciﬁcations subject to change!Technical data6 Technical data62526Important note:Please use the original accessories recommended by Eppendorf.
