网蜂科技开发板CC2530F256实现AD控制(Realization of Watchdog Timing by Network Bee Technology Development Board CC2530F256)

sim900a gprs上传数据，51单片机c语言源程序(sim900a gprs upload data, 51 c language source)

ADNS3080鼠标芯片的Arduino程序 采用SPI进行通信(ADNS3080 mouse chip Arduino program uses SPI communication)

说明：  使用stm32和51单片机实现声源定位然后控制摄像头系统的资料，有论文及代码(Using STM32 and 51 single chip microcomputer to achieve sound source positioning, and then control the camera system information, there are papers and codes)

基于51单片机的数字电子秤，有文档的详细说明(A digital electronic scale based on 51 single chip microcomputer with detailed description of the document)

通过RS485端口不停地发送数据0xaa用示波器观察RS485端口A、B信号线上的波形或者用RS485接收器接收发送的字符。(Through the RS485 port to send data continuously 0xaa observed with an oscilloscope RS485 ports A, B signal waveforms or use the RS485 line receiver sends characters.)

FUNCTION: circular_arc_center_close draws closed arc centered at c1 with radius rad points c2,c3. Arc is closed with either PIE or CHORD.

说明：  通过bh1750与stm32连接，检测光照强度并显示在液晶屏(Through the connection of bh1750 and STM32, the light intensity is detected and displayed on the LCD screen)

74164串行口转并行口芯片驱动模块，使用EMC系列单片机(74164 serial port to parallel port chip driver module, using EMC Series MCU)

超简单断电复原3档亮度调光程序,每次开机都是低亮，不晃眼 低亮不是使用Pwm，而是使用电阻漏一部分电流给LED，超省电，无频闪，亮度随便调 源程序是东成的(3 super simple file recovery power brightness dimming process, each boot are low-light, non-dazzling light rather than the use of low-Pwm, but part of the use of resistance leakage current to the LED, ultra-low power, no strobe, just tune brightness source procedures of the East into)
