freeRTOS的常见使用例程，涉及队列、消息，进程等(Demo about freeeRTOS)

说明：  ADS112C04驱动，可采集电压，产生恒定电流等(ADS112C04 Driver,can Acquisition voltage,and Generating a constant current)

说明：  用数码管显示电压，发送到串口，然后有高低电压报警，只有部分代码(Display voltage with digital tube, send it to serial port, then alarm with high and low voltage, only part of the code)

基于stm32f103的多路ADC采集，将采集的电压传入到DMA设定的内存中，在通过均值滤波得到比较准确的数据(Based on the multi-channel ADC acquisition of stm32f103, the collected voltage is transferred to the memory set by DMA, and the more accurate data are obtained by means of mean filter.)

电能计量芯片ATT7053的读写程序。用于8051单片机完成的。利用C语言完成的。可以用于新国标表的开发。(Energy Metering IC ATT7053 reading and writing program. For 8051 completion. The use of C-complete. Can be used for the development of a new national standard form.)

stm32f401使用ad模块pcf8591(using pcf8591 by the stm32f401)

OLED12864屏汇编语言底层显示程序，有详细注释，SSD1303，SSD1306驱动IC的OLED屏51单片机汇编驱动显示程序(OLED12864 assembly language to the bottom screen display program, there are detailed notes, SSD1303, SSD1306 driven OLED screen IC driver display program 51 microcontroller)

8通道24位AD转换器ADS1218操作函数，包含寄存器设置和flash操作。(8-channel 24-bit AD converter ADS1218 operating functions, including register settings and flash operation.)

PIC16F690控制RFM12无线通信模块进行数据发送(PIC16F690 RFM12 wireless communication module for controlling data transmission)

ekf，即扩展卡尔曼滤波器，对于研究电机滑膜控制有所帮助(ekf, ie, extended Kalman filter, the research motor control synovial helpful)
