光立方，8*8*8的，源代码，原理图和电路板我会陆续上传( Light cube, 8* 8* 8, the source code, schematics and board I will continue to upload)

Himax LCD Initialization code

液晶显示器与单片机接口电路程序，实现液晶显示对于信号源发生信号的控制和显示(LCD and microcontroller interface circuit procedures, LCD occurred signal source for the control signal and display)

这stm32f746描述了如何使用DAC外围 产生使用DMA控制器的信号。 在用户按键每按一下，信号已被选中，可监测 DAC通道： • 三角波形（通道1）。 -自动扶梯的波形（1频道）使用DMA传输。(This STM32F746 code provides a description of how to use the DAC peripheral to generate several signals using DMA controller. For each press on User push-button, a signal has been selected and can be monitored on the DAC channel one: - Triangle waveform (Channel 1). - Escalator waveform (Channel 1) using DMA transfer.)

STM32F407通过ADC，DMA输出 幅值，频率可调正弦波(STM32F407 outputs amplitude and frequency adjustable sinusoidal wave through ADC and DMA)

用于模块化多电平逆变器最低电平调制程序,很好的控制方法(Minimum level modulation program for modular multilevel inverters)

stm32f103vet6实现printf重载(printf function about stm32f103vet6)

用的是时钟芯片pcf8583，可以正常显示时间,并带有有Proteus仿真，非常形象！，已通过测试。 (Is clock chip pcf8583, can properly display the time, and with Proteus simulation, the very image of , Has been tested.)

采用51核单片机+375A usb主控芯片驱动hp打印机，该源码已完全调试ok。(51 nuclear Singlechip+ 375A usb host chip driver hp printer, the source has been fully debug ok.)

利用单片机定时器产生高低电位各0.5毫秒的方波，该方波再经二阶滤波变成1K赫兹的正弦波，即为音频信号(To produce high and low potential of each 0.5 ms using SCM timer Fang Bo, the square wave and then by two order filter into 1K Hz sine wave, namely for audio signal )
