current-meter

这是单片机的一个非常好的一个资料，大家可以参考一下，单片机是个非常有用的入门级的，以后学ARM就非常简单了！学单片机最重要的就是看芯片资料(This is a very good single-chip data, we can refer to the microcontroller is a very useful entry-level, after school ARM is very simple! The most important thing is to learn microcontroller chip information see)

基于MAP430F149单片机的典型例题，很有帮助(Microcontroller based MAP430F149 a typical example, very helpful)

基于正点原子stm32的频谱 a1读取ad信号显示(Punctuality atomic spectrum based stm32 a1 read signal display ad)

nrf905 接收机程序 89C52 验证通过 绝对好使(nrf905 receiver program 89C52 verified through absolutely so)

TDC-gp21超声波时间测量，用于热表中测量逆流与顺流的时间，进出口温度以及高速晶振的校准 基于430开发，开发环境 IAR5.1(TDC- gp21 ultrasonic measuring time, time for heat measurement of upstream and downstream in the table, the import and export temperature and the calibration of high-speed crystals Based on the 430 development, IAR5.1 development environment)

PWM调光 1、学习目的：利用定时器产生PWM，了解原理和使用方法 2、硬件要求：LED灯 定时器 3、试验现象：LED灯由亮到灭，由灭到亮逐步变化，也就是调光现象(PWM dimming, learning objectives: the use of the timer to generate PWM understand the principles and use hardware requirements: LED lamp timer test phenomenon: LED lights from bright to off, gradually changes from off to bright, that is, adjusted optical phenomena)

vb单片机上位机例程 很详细的例子，直接可用 适合初学者 (vb example)
