模块测试============================================================
1：朋友拿到模块后，先不急着调电位器，电位器出厂已调到幅度调到 2V VPP。朋友调试 出信号后，如果有需要再调节电位器，调幅度。 2：问我按照你的方法接怎么不出信号。 答：给大家的模块和程序都是已经调试成功程序是标准 51 C 程序。如果是别的类型单片机 如 STM32，AVR，MSP430 请朋友自行移值。朋友要注意一些比如自已的单片机 IO 口是不 是连其它器件，比如 DS18B20 DS1302 数码管等一些器件。这些器件会影响时序，导致出 不来信号。 3：为什么程序给了 1K 的信号，但出来频率相差很多。 答：这里由于 D0-D7 数据口跟单片机数据口没有连好导致。请朋友仔细检查核对后，肯定 OK！ 4：你的模块可以用 3.3V 供电吗？ 答：模块设计在 5V 供电，在 3.3V 勉强能用，但不建议！ 5：我用示波器量，出来的波形幅度怎么用 20 多 V？ 答：模块采用 5V 供电，不可能出 20 多 V，唯一可能就是示波器表笔打到*1 档，再把示波 器打到*10 就恢复了。 6：为什么我的正弦波出来了，但方波出不来 答：可能是调节占空比电位器调的太多了，重新调试即可解决

RF_OUT 端能测试到对应输出 1KHz 正弦波信号幅度 2V VPP。如需测试方波，调节可 变电位器，在 VOUTP 和 VOUTN 端测试到方波。电位器调节占空比

For technological reasons, these electronic components are very sensitive to overvoltages and consequently therefore to electrostatic discharge:These devices are referred to in German as Elektrostatisch GefährdetenBauelemente/ Baugruppen: ºEGBºThe more frequent international name is:ºESDº (E lectrostatic Sensitive Device)The following symbol on plates on cabinets, mounting racks or packages draws attention to the use of electrostatic sensitive devices and thus to the contact sensitivity of the assemblies concerned:ESDs may be destroyed by voltages and energies well below the perception threshold of persons. Voltages of this kind occur as soon as a device or an assembly is touched by a person who is not electrostatically discharged . Devices exposed to such overvoltages cannot immediately be detected as defective in the majority of cases since faulty behavior may occur only after a long period of operation.Precautions against electrostatic dischargeMost plastics are capable of carrying high charges and it is therefore imperative that they be kept away from sensitive components.When handling electrostatic sensitive devices, make sure that persons, workplaces andpackages are properly grounded.APPENDIX Handling ESD assembliesA general rule is that assemblies should be touched only when this cannot be avoided owing to the work that has to performed on them. Under no circumstances should you handle printed-circuit boards by touching device pins or circuitry.You should touch devices only if● you are grounded by permanently wearing an ESD wrist strap or●you are wearing ESD shoes or ESD shoe-grounding protection straps in conjunctionwith an ESD floor.Before you touch an electronic assembly, your body must be discharged. The simplest way of doing this is to touch a conductive, grounded object immediately beforehand ± for example, bare metal parts of a cabinet, water pipe etc.Assemblies should not be brought into contact with charge-susceptible and highly insulating materials such as plastic films, insulating table tops and items of clothing etc. containing synthetic fibers.Assemblies should be deposited only on conductive surfaces (tables with an ESD coating, conductive ESD cellular material, ESD bags, ESD shipping containers).Do not place assemblies near visual display units, monitors or television sets (minimum distance to screen > 10 cm).Measuring and modifying ESD assembliesPerform measurements on ESD assemblies only when● the measuring instrument is grounded ± for example, by means of a protective conductor± or● the measuring head has been briefly discharged before measurements are made with a potential-free measuring instrument ± for example, by touching a bare metal control cabinet.When soldering, use only grounded soldering irons.Shipping ESD assembliesAlways store and ship assemblies and devices in conductive packing ± for example, metallized plastic boxes and tin cans.If packing is not conductive, assemblies must be conductively wrapped before they are packed. You can use, for example, conductive foam rubber, ESD bags, domestic aluminum foil or paper (never use plastic bags or foils).With assemblies containing fitted batteries, make sure that the conductive packing does not come into contact with or short-circuit battery connectors. If necessary, cover the connectors beforehand with insulating tape or insulating material.GlossaryBaud rateRate of speed at which data is downloaded. Baud rate is specified in Bit/s.BootA loading process which downloads the operating system in the working memory of the operating unit.Command SetHex Code, the MCU can control the TFT Module via the command set.Configuration fileIt can be created by the softwares.DownloadDownload the image, configuration files and data through mini USB port or USB port.Download modeThrough mini USB port or USB port.GlossaryFlash memoryProgrammable memory which can be electrically deleted and written to again segment-by-segment.Half Brightness LifeThe period of time after which the brightness tube only achieves 50% of the original value.Input fieldEnables the user to enter values which are subsequently sent to the MCU.MCUMicro Control Unit, it is widely used in the industrial control.Normal operationOperating unit operating mode in which messages are displayed and screens can be operated.GlossaryOutput fieldDisplays current values from the MCU on the operating unit.Process screenThe display of process values and process progress on the operating unit in the form of screens, which may contain graphics, texts and values.RS485Standard interface for serial data transfer at a very high transmission rate.ScreenA screen displays all the logically related process data on the operating unit, wherebythe individual values can be modified.Touch panelThis is an operating unit without a keyboard. The touch panel (abbreviated to TP) is operated via the contact-sensitive screen elements.。
