CH451的8*8 LED驱动器的键盘驱动程序(CH451 *88 of the LED driver keyboard driver)

基于单片机的智能家居系统：红外遥控，红外报警 ，光与LED灯，串口显示光信息 ，时间显示，电机正转，，电机反转，温度报警 (Microcontroller-based Smart Home System: Infrared remote control, infrared alarm, light and LED lights, serial optical information display, time display, the motor is transferred, motor reversal, temperature alarm)

VSG等效为SG的visio构图，可以直接复制到word中，visio2010制作，vsd格式(VSG as SG，made by MS visio2010)

stm32L151单片机工程，同上位机通信，LORA通信 。可和上传的VS工程COM&&LOCK配套使用。(A stm32L151 project, have function of communication with PC seriaport and LORA module)

利用28335自带的ADC采集两路模拟正弦信号，用DMA方式将采样值写入内存，用epwm控制采样周期。利用FFT求得两路正弦信号的相位差。(Sampling two analog sinusoidal signals, write them to the memory by DMA controller. The sampling period is controlled by the EPWM module. Calculate the phase difference by FFT method.)

说明：  关于STM32单片机的学习资料，包含一些模块程序与结构图，内含PPT讲解(About STM32 microcontroller learning materials, including some module program and structure diagram, including ppt explanation)

ATSHA204 主要特性： 1，SHA-256 Hash算法 2，有保证的唯一的72-bit序列号； DS28CN01　６４－ｂｉｔ 不仅有软件加密，内部还有高质量硬件加密。 3，16个槽口的4kbits EEPROM： 4Kbits / 8 = 512Bytes 每个槽口32bytes 4，I2C接口, 单线接口 5, 和Atmel AT88SA102S，AT88SA10HS 6, i2c 地址默认为0xc8； 还可以configuration zone改变地址。(CryptoAuthentication Device Family Atmel offers the industry s widest selection of hardware authentication and encryption devices. The portfolio is currently comprised of three parts with several others under development. Our CryptoAuthentication devices provide confirmation that hardware and software products are real, which is what authentication is all about. The devices are extremely cost-effective and come in exceptionally small packages.)
