modbus通信程序,可用组态软件的驱动程序开发(modbus communication program, available configuration software driver development)

说明：  基于51单片机的按键例程，常见问题： 1. 按键无反应 请您确认程序是否下载成功，连线正确无误，确认无误后还是无效果的话，将排线重新插拔下，单片机拿下来重新安装，重启开发板试试！(Key routines based on 51 single chip microcomputer,common problems: 1. Press the key and no response. Please confirm whether the program was downloaded successfully and the connection is correct. If it is still ineffective after confirmation, plug and unplug the cable again, take down the MCU and reinstall it. Restart the development board to try!)

说明：  LPC1788 + emWin 方案移植(Lpc1788 + EMWIN solution migration)

与沉默的开关为iOS，精选ios编程学习源码，很好的参考资料。(And the silence of the switch is iOS, select learning IOS programming source code, a good reference.)

Beginning Visual C_ 2012 Programming

说明：  canopen移植,在STM32F103RBT6上移植成功(canopen stm32f103rbt6)

STM32F107 音乐播放器、模拟输入混音、音量控制、静音控制。 MDK编译测试成功 (STM32F107 music player+ analog input mixer+ volume control+ mute control MDK version)

基于AVR单片机的MPPT程序（爬山法），非常好用！(AVR microcontroller based MPPT program (hill climbing), very easy to use!)

说明：  设计一个正弦信号发生器，使用凌阳公司的16位单片机SPCE061A作为中央控制器，结合DDS芯片AD9850，产生0～15MHz频率可调的正弦信号,正弦信号频率设定值可断电保存；使用宽频放大技术，在50Ω负载电阻上使1K～10MHz范围内的正弦信号输出电压幅度VP-P=6V±1V；产生载波频率可设定的FM和AM信号；调制信号为1KHz的正弦波，调制信号的产生采用DDS技术，由CPLD和Flash ROM加上DAC进行直接数字合成；二进制基带序列码由CPLD产生，在100KHz固定载波频率下进行数字键控，产生ASK，PSK信号。(Design of a sinusoidal signal generator, the use of Sunplus 16-bit MCU SPCE061A as the central controller, combined with DDS chip AD9850, have adjustable frequencies 0 ~ 15MHz sinusoidal signal, sinusoidal signal frequency settings can be stored power using broadband amplification, in a 50Ω load resistor to 1K ~ 10MHz sinusoidal signal within the output voltage amplitude VP-P = 6V ± 1V generating the carrier frequency of the FM and AM can be set signal 1KHz sine wave modulation signal, modulated signal generation using DDS technology, coupled by the CPLD and Flash ROM DAC for direct digital synthesis binary baseband sequence code generated by the CPLD in a fixed carrier frequency 100KHz digital keying, resulting in ASK, PSK signals.)
