8255A(2)7．2 可编程并行接口由于我们现在常用的微机系统均以并行方式处理数据，所以，并行接口也是最常用的接口电路。
并行接口有以下几方面的特点：（1）并行接口是在多根数据线上，以数据字节（字）为单位与输入／输出设备或被控对象传送信息的，如打印机接口、A／D、D ／A转换器接口、IEEE－488接口、开关量接口、控制设备接口等。
在实际应用中，凡在CPU与外设之间同时需要两位以上信息传送时，就要采用并行口。
并行口适用于近距离传送的场合。
由于各种I／O设备和被控对象多为并行数据线连接，CPU用并行口来组成应用系统很方便，故使用十分普遍。
（2）并行传送的信息，不要求固定的格式，这与串行传送的信息有数据格式的要求不同。
例如，异步串行通信的格式是一个数据，它包括起始位、数据位、校验位和停止位。
（3）从并行接口的电路结构来看，并行口有硬线连接接口和可编程接口之分。
硬线连接接口的工作方式及功能用硬线连接来设定，用软件编程序的方法不能加以改变；如果接口的工作方式及功能可以用软件编程序的方法加以改变，则就叫可编程接口。

The key switch and optional headlight and off-aisle wand switches are clustered in the back portion of the console. The directional switch (forward/reverse) is located at the front of the console for easy fingertip operation. The horn button, function selectors, and battery gauge are located in the central part of the console.(A) – Controls the machine’s power (ON/OFF) with a key for safety. All operational settings are retained even when the power is turned off and on. This also serves as a reset switch when errors or faults occur.(OPTIONAL) (B) – ON/OFF control for the water supply to the wand and vacuum motor for the optional Off-Aisle Wand.(OPTIONAL) (C) – ON/OFF control for the optional headlights. (D) - Displays the level of charge remaining in the machine’s batteries. The gauge consists of 10 LEDs. (3 Green, 4 Amber, 3 Red) If the battery life is low, the battery gauge bar icon will be flashing to inform the operator that the machine is almost out of power. Once this signal is displayed, all functions will shut off, including transport mode. The operator must then turn the key switch OFF and then ON to reset the machine. The machine will then have only a few minutes left of reserve power to briefly use Vacuum Only mode to pick up any remaining solution on the floor andTransport mode to return to the charging station. This gauge will also display a fault code if the system has an error. This code is represented by a specific number of flashing LEDs. See Fault/Diagnostic Codes for specific code information.(E) – Adjusts the amount of solution being dispensed to the floor while in one of the scrub modes. Turn the knob clockwise to increase the amount of solution being dispensed. The amount of solution applied is variable to a maximum of 1 GPM.(F) – This knob is used to select the desired operation mode of the machine. See Operation Modes for information about each mode. (G) – Depressing this button will activate the machine’s horn.(H) – Flipping this switch to the down position will set the machine to move forward. Flipping it to the up position sets the machine to move in reverse.Control Console Key SwitchOff Aisle Wand SwitchHeadlight Switch Battery GaugeSolution Control KnobMode Selector Knob Horn Button Directional Switch1.When the machine is running in this mode, the machine will perform all operations. This mode can be used for day-to-day tasks under normalconditions. When the operator sets the directional switch to forward and activates the accelerator pedal, the solution pump will turn on, the brushes will turn on and be lowered to the floor, as well as the rear squeegee. While operating in this mode, the solution will be dispersed into the brushes, which will scrub the floor allowing the chemical in the solution to break down the dirt on the floor. As the machine continues to move forward, the rear squeegee and vacuum system will recover the dirt and dispensed solution. If the operator stops moving, the machine will automatically raise the scrub deck and turn off the brushes. If the directional switch is changed to reverse the machine will continue to operate normally, only the rear squeegee will raise up.2.This mode is similar to Regular Scrub. The machine will continue to operate the same was as if it was in Regular Scrub Mode , only this mode applies more solution and brush pressure is increased. This mode is used for high traffic areas and areas that have been heavily soiled, but do not require time for the solution to soak.3.When the machine is running in this mode, the machine will perform all operations except dirty solution recovery. This mode can be used if the floor is heavily soiled and the chemical will need additional time to emulsify grease and oils that are on the floor. When the operator sets the directional switch to either the forward or reverse position and activates the accelerator pedal, the solution pump will turn on, the brushes will turn on and be lowered to the floor. While operating in this mode, the solution will be dispersed into the brushes, which will scrub the floor allowing the chemical in thesolution to break down the dirt on the floor. As the machine continues to move forward or back, the rear squeegee and vacuum system are not on, which allows the solution to stay on the floor emulsifying the grease and oil. If the operator stops moving in either direction, the machine will automatically raise the scrub deck and turn off the brushes.Operation ModesRegular Scrub Mode Heavy Scrub Mode Double Scrub ModeAfter double scrubbing, the operator should use the vacuum only mode to recover the dirty solution water from the floor.4.When the machine is running in this mode, the machine will only lower the rearsqueegee and turn on the vacuum system to recover the dirty solution from the floor. This mode is usually chosen after double scrubbing to recover the dirty solution but it can also be used to pick up spills. When the operator sets the directional switch to forward , the rear squeegee will be lowered to the floor as the vacuum turns on, pulling the dirty solution water from the rear squeegee into the recovery tank. If the operator stops moving forward and sets the directional switch to reverse, the rear squeegee will retract (protecting it from damage) and the vacuum motor will turn off after a few seconds. If the operator quits moving in either direction, the machine will automatically raise the squeegee and turn off the vacuum motor after a few seconds.5.When the machine is set in this mode, none of the cleaning functions of the machine will operate. This mode is only used to transport the machine from one location to another at a faster rate of speed.6. This control will adjust the amount of solution that is being dispersed to the floor while in one of the scrub modes. Adjust the control clockwise to increase theamount of solution being dispersed. The amount of solution applied is variable to a maximum of 1 GPM.7.This gauge displays the level of charge remaining in the machine’s batteries. The gauge consists of 10 LEDs. (3 Green, 4 Amber, 3 Red) If the battery life is low, the battery gauge bar icon will be flashing to inform the operator that the machine isalmost out of power. Once this signal is displayed, all functions will shut off, including transport mode. The operator must then turn the key switch OFF and then ON to reset the machine. The machine will then have only a few minutes left of reserve power to briefly use Vacuum Only mode to pick up any remaining solution on the floor and Transport mode to return to the charging station. This gauge will alsodisplay a fault code if the system has an error. This code is represented by a specific number of flashing LEDs. See Fault/Diagnostic Codes for specific code information.Vacuum Only Mode Transport Mode Solution Control KnobBattery GaugeFault / Diagnostic CodesWhen an error or fault occurs within the machine, a fault code will appear on the battery gauge represented by a specific number of flashing LEDs. The figure below shows a listing of the different codes.FAULT / DIAGNOSTIC CODES DECALOnce the solution tank has become empty, the battery gauge will blink a solid 9 LEDs at a constant interval to alert the operator that the solution tank needs to be filled.If the battery life is low, the battery gauge bar icon will be flashing to inform the operator that the machine is almost out of power. Once this signal is displayed, all functions will shut off, including transport mode. The operator must then turn the key switch OFF and then ON to reset the machine. The machine will then have only a few minutes left of reserve power to briefly use Vacuum Only mode to pick up any remaining solution on the floor and Transport mode to return to the charging station.The SCV is equipped with a power save feature to conserve battery power. If the key switch power is left ON and none of the controls are activated for a period of fifteen minutes, the SCV automatically goes into “power down mode” and turns OFF the power to conserve your batteries in case the operator forgets to turn the key switch off or leaves the machine unattended.Empty Solution Tank Indicator Low Battery Indicator Power Save ModeThe steering wheel is adjustable for operator comfort by pulling the tilt-steering lever up and positioning the steering wheel up or down (there are three possible positions). Pulling on the tilt-steering lever andpositioning the steering column in an upright position provides the operator with more room whenclimbing up and down the machine.Located on the right side of the operator compartment on the floor is the accelerator pedal. This pedal controls the propelling speed of the machine. The farther the pedal is pushed down the faster the machine will travel. As discussed earlier, thedirectional switch governs the direction of travel the machine will take. Switching the directional switch with the pedal depressed will make your machine changedirections (a very slight delay may occur before the direction of travel changes when switching directions on the fly). The accelerator pedal is interlocked with the seat switch, making machine propulsion not possible without the operator sitting on the seat. The accelerator pedal is also linked to the machine’s dynamic braking system . During operation, when the accelerator pedal is released, the dynamic braking system will automatically halt the movement of the machine without need for an additional brake pedal.The ergonomically designed seat is located on top of the solution tank. There is a lever under the seat that allows the operator to adjust the seat forward or backward for operator comfort. There is an interlock switch located inside the seat. This makes it impossible to engage the traction drive circuitry without the operator on the seat. If the operator were to fall off the machine, the traction drive circuitry would turn off.Located on the lower front of the control console, this switch controls the direction in which the SCV will move when the accelerator pedal is activated. Flipping thisswitch to the down position will set the machine to move forward. Flipping it to the up position sets the machine to move in reverse.This machine is equipped with an Electro-magnetic brake built-in on the traction drive motor. When the machine’s power is turned off (using either the key or theemergency button), the E-mag brake is activated and the traction motor is prevented from moving.Operation of ControlsAccelerator Pedal Seat Directional Switch Parking Break Steering WheelThis button is located in the middle of the electrical panel that is directly underneath the operator’s seat. When the red emergency button is pressed, power will be turned off. Use this button in case of a machine emergency. The red knob needs to be raised in order to run the machine. To reactivate, turn the knob as shown by the arrows on the switch and the button will pop up. All operational settings are retained evenwhen the power is turned off and on.The circuit breakers are located next to the emergency disconnect button. The 6-amp breaker (indicated by black arrow) protects all auxiliary circuits on the machine. The 100-amp breaker (indicated by white arrow) protects the main system circuit (TRIO controller). Each main component is individually protected with an internal breaker built-in the controller. (See fault code table) and can be reset by turning the key switch off a few seconds and then on again. The 100 amp circuit breaker can also be used as a main powerdisconnect, this should be used only in case of emergency. When tripped the breaker removes power from the main controller and all auxiliary power circuits.The battery compartment is located on the rear of the machine under the recovery tank. Unlatching the two safety latches on the side of the machine enables the operator to tilt the recovery tank and access the batteries for servicing and maintenance (make sure recovery tank has been drained before tilting). The battery compartment contains six, 6-volt batteries connected in series. Connect the batteries according to the batteryconnection diagram (see diagram ). The recommended batteries are 275Ah (Minuteman P.N. 956740). The two batteries positioned in the center are offset and held in position by two steel spacers. These spacers keep the batteries from sliding inside the batterycompartment during machine use and prevent undesired stresses in the battery cables. Be sure to replace these spacers whenever reinstalling batteries.Emergency Disconnect Button Circuit Breakers Battery CompartmentBattery Connection Diagram ArrayBatteries Installed with SpacersMinuteman offers two deck types (Cylindrical and Disc) to fit your specific needs. The SCV design is very dynamic wherein the decks are interchangeable in a matter of minutes whenever necessary (removal of four bolts, one hose, and one electrical connection). The cylindrical brush deck has five built-in spray jets to uniformly dispense cleaning solution on the floor and a wet sweeping debris tray to collect loose objects on the floor. The disc brush deck dispenses cleaning solution through the two center hubs and the solution is contained within the bristle area for efficient agitation of cleaning solution to the floor and channeled to the rear of the machine. The disc brushes are also easily removed and installed by easily removing the side deck covers and releasing the quick release clamp. Another nice feature that these scrub decks have is the ability to have uniform brush pressure applied to the floor at all times. Since the scrub deck brush pressure is computer controlled, it will automatically adjust and compensate to uneven contours on the floor while maintaining brush pressure.A B C D E F G H Main HousingSpray Bar w/ SprayjetsAccess Door (2)Access Door Wingnut (6)Debris BoxWater Supply Hose ConnectionMounting BracketPower ConnectorIJKLMNOBrush Motor (2)Pulley Cover (2)Bolt (4)Helical Lock Washer (4)Flat Washer (4)Black Squeegee Adj.

Remove the two access doors(one on each end) by removingthe three wing nuts on each door.c. Install the brushes by slidingthem through the accessopening. (see figure for correct orientation.)Scrub Deck Installation Installation Instructionsd. Align the notches on the brush with the drive pins on the hub.e. Push the brush all the way in until it bottoms out.f. Insert the access door hub into the other end of the brush.g. Reinstall the wing nuts and yellow 3 sided knobs and tighten.As previously mentioned, the scrub deck brush pressure is computer controlled. However, when interchanging the two types of decks, an additional step must be taken to ensure that the controller correctly compensates the pressure for the type of deck that is currently installed.Inside the main electrical box, beneath the seat there is an Orange/Violet jumper wire (shown disconnected in Figure 1) that may or may not be connected to the terminal block, depending on the type of scrub deck that was originally ordered with the machine. When using the Disk Scrub Deck, the wire is disconnected. When using the Cylindrical Scrub Deck, the wire is connected to the terminal block located in the electrical box, beneath the TRIO Controller. This terminal block is divided into five sections, each separated by a divider. The four leftmost sections contain one column each of spade terminals. The section on the right contains two columns of spade terminals (this section also contains four Red/Black wires, not shown in Figure 2 for clarity). The Orange/Violet wire must be connected to a spade terminal in the section with two columns when using the Cylindrical Scrub Deck ONLY!When switching from the Cylindrical Scrub Deck to the Disk Scrub Deck, be sure to disconnect the Orange/Violet wire. When switching from the Disk Scrub Deck to the Cylindrical Scrub Deck, connect the Orange/Violet wire to any available spade terminal in the section that contains two columns (shown in Figure 2) and the Red/Black wires.Figure 1 Figure 2Jumper wire disconnected Jumper wire connected to terminal block Important Note when Interchanging Scrub Decks。

IAP15F2K60S2仿真芯片加MAX3232的在线调试电路图
STC单片机片上仿真法文/杜洋有单片机初学者问了我这样一个问题：单片机真是个好东西，可以实现我的很多想法，就是在编程开发的时候太麻烦，每次改动都要重新编译、下载，再等待着问题的出现。
仅调试一个参数就要花上几个小时的时间。
对于我们这些没什么经验的编程菜鸟来说太麻烦了。
我想单片机技术发展至今，应该有更便捷的开发工具吧。
杜老师你平时是怎么开发单片机软件的？有什么秘诀传授一下呗！我的回答是：当然有秘诀，那就是使用“仿真功能”。
什么是仿真？它如何实现更快捷的开发呢？详见下文。
【什么是仿真】什么是仿真？我们举一个汽车设计的例子来说明一下吧。
大家一定在影视剧或电视广告中看过这样的镜头：在一个大大的厂房里，一辆崭新的小汽车正在以很高的速度撞向一面厚厚的水泥墙。
坐在车上的两个人面不改色心不跳，一动不动地等待着死亡。
他们为何如此冷静，因为“他们”是实验用的假人。
说时迟那时快，汽车已经撞到了墙上，巨大的声响夹杂着飞溅的碎片充满了空间，汽车在撞击中破了相。
旁边的几台高速摄像机记录下了这一切。
这是一次真实的撞击实验，目的是为了得出这款车型在出现意外时，是否能保住人的小命。
安装在假人身上的传感器所得出的数据，能帮助工程师们发现安全隐患，改进汽车的设计。
可以说以上就是一次仿真，一辆真车和两个假人有计划地撞墙，模拟了真实车祸情况。
仿真让实验变得可能，因为没有一个真人愿意坐在车里参与这场实验。
当真实情况很难在开发时再现时，仿真就可以帮助开发者完成必要的实验。
这就如同单片机开发中，我们在自己的实验板上去开发一款产品一样。
当我们设计好了一个产品的功能，我们要在实验板上模拟用户的操作，看看操作是否正常，产品的反应速度和稳定性如何。
这些都是在仿真——模仿用户使用的真实情况。
有朋友会问了：如果这就是仿真，那还有什么好讲的呢？嗯，如上所说的仿真只是广义上的仿真，凡是在实验室里用实验板或工程样机模拟用户使用的过程，都可以算是仿真。
而还有一种狭义的仿真，就是下面要重点介绍的内容。

2.2.4 、前沿消隐 由于存在寄生电容， MOSFET 在导通瞬间，会产生一个脉冲电流。 CS6552/CS6552F 内部集成有前沿消隐功能，当 MOSFET 导通的瞬间，设计有 500ns 的前沿消隐时间，在这 段时间内，电流比较器停止工作，避免脉冲电流让电流比较器发生误翻转。
