828DPLC

基于TLC5620和51单片机实现简单的信号发生器，可以调节方波，三角波的频率幅度，正弦波频率可调，幅度有两个档位。(51 MCU based TLC5620 and simple signal generator can adjust the square wave, triangle wave frequency range, adjustable sine wave frequency, amplitude has two stalls.)

51单片机读写sd卡程序,包括对手动卡的读取片区，擦除片区，写入片区，51 单片机模拟spi时序对sd卡进行操作(51mcu read and write sd card)

说明：  一本讲述proteus与51单片机仿真的书(A book about the simulation of Proteus and 51 single chip computer)

Test ifnonnull extends DxTestCase.

说明：  基于autosar的ECU软件开发方法，适合初学autosar的工程师，比较容易入门(Development Method of ECU Software Based on Autosar)

说明：  物联网系统的stm32开发代码，包含一氧化碳，温湿度(Internet of Things System)

STM32单片机用使用的心电传感器的参考代码，可以检测人体表面的心电的变化规律(STM32 microcontroller using ecg sensor reference code, can detect the changing rule of the human body surface ecg )

此代码为stm32将外部flash如w25q32模拟成U盘，对内部数据进行读写操作，此工程已经验证通过，希望对大家用一定的帮助(This code is stm32, which simulates external flash such as w25q32 into a U disk to read and write internal data. This project has been verified and passed. I hope it will be of some help to you)

一份直立车模调试指南，只要有点单片机基础的都可以看懂，从传感器介绍到数据处理，滤波，到姿态的计算。。。能带给你很大的用处(An upright Cars commissioning guide, just a bit microcontroller based can understand, from the sensor introduced to data processing, filtering, to the attitude of the calculations. . . Can bring you a lot of useful)

基于STM32F1x的ADC电压检测代码(ADC Voltage Detection Code Based on STM32F1x)
