Description: 板上资源: LM2576电源,MAX3232电平转换芯片,11.0592M有源晶振,ATMEGA128L,FM32256(铁电),滑槽式SIM卡座,40PZIF接插件,通信 模块支持CM320,TC35i,MC35i,MC39i,GTM900A/B等模块。 使用方法:1、不焊接M128和FM32256以及晶振,将桥接电阻R29,R30,R31焊上,就是标准串口无线MODEM,根据模块不同可以支持GPRS和CDMA, 当然也可以作为GSM猫或者短信猫来使用。 2、焊上M128芯片,FM32256可以根据实际需要决定是否使用,除了支持上面的应用模式外,还能做成不需要上位机的透明传输模块, 实现单片机或者一些非计算机设备无线上网传输数据的要求。-On-board resources: LM2576 power, MAX3232 chip-level conversion, 11.0592M active crystal, ATMEGA128L, FM32256 (Ferroelectric), slide-type SIM card connector, 40PZIF connectors, communications module supports CM320, TC35i, MC35i, MC39i , GTM900A/B modules. Usage: 1, non-welding as well as the M128 and FM32256 crystal will bridge resistor R29, R30, R31 welding, that is the standard serial wireless MODEM, according to the different modules can support GPRS and CDMA, of course, can be used as a cat or GSM SMS cat to use it. 2, welding on the M128 chipset, FM32256 can decide whether or not the use of actual needs, in addition to supporting the application of the above model, but also do not need to make PC transparent transmission module, the realization of single-chip or a number of non-computer equipment to transmit data wireless Internet access requirements.

[ARM-PowerPC-ColdFire-MIPSCPLD

Description: 项目的研究内容是对硅微谐振式加速度计的数据采集电路开展研究工作。硅微谐振式加速度计敏感结构输出的是两路差分的频率信号,因此硅微谐振式加速度计数据采集电路完成的主要任务是测出两路频率信号的差值。测量要求是:实现10ms内对中心谐振频率为20kHz、标度因数为100Hz/g、量程为±50g、分辨率为1mg的硅微谐振式加速度计输出的频率信号的测量,等效测量误差为±1mg。电路的控制核心为单片机,具有串行接口以便将测量结果传送给PC机从而分析、保存测量结果。 按研究内容设计了软硬件。软件采用多周期同步法实现高精度,快速度的频率测量方案,并使用CPLD编程实现,这也是最难的地方。硬件采用现在流行的3.3V供电系统,选用EPM240T100C5N和较为实用的AVR单片机芯片Atmega64L,对应3.3V供电系统,串行接口使用MAX3232。 最后完成了PCB板的制作,经反复调试后得到了非常好的效果。采集的数据满足项目研究内容中的要求,当提高有源晶振的频率时,精度有大大提高了,此时已远远满足了项目中高精度,快速度测量的要求。另外,采用MFC编程编写了上位机的数据接收和数据处理专用软件,集数据采集,运算,作图,保存功能于一体。 此为CPLD语言部分-err
