stm32学习 十三：RS485总线的使用 十四：TFT屏的图片，中文和字符显示(stm32 learning 13: RS485 bus use 14: TFT screen pictures, Chinese, and character)

STM32L152VB的AD采集程序，7通道DMA方式采集，通过串口发送到PC，本人查阅多方资料亲自编程测试，可直接用。附带STM32L152VB工程模板，本人根据资料自己建的。(The AD STM32L152VB acquisition program, 7 channel DMA acquisition, through the serial port to send to the PC multi access information, I personally programming test, can be directly used. With STM32L152VB project templates according to the data, I built myself. )
