【STM32F429开发日志】（0）+示波器

stentor

 自己之前做的一个示波器，只用了LCD的底层驱动，没用系统及GUI
将C文件替换到固件包的STM32F429I-Discovery_FW_V1.0.1\Projects\Template下，运行即可
代码贴上看看：

  * @file    ADC_TripleModeInterleaved/main.c
  * @author  MCD Application Team
  * @version V1.0.1
  * @date    11-November-2013
  * @brief   This example provides a short description of how to use the ADC 
  *          peripheral to convert a regular channel in Triple interleaved mode 
  *          using DMA in mode 2 with 8.4Msps .

源码没贴完整啊  请详细贴出源码 和操作方法 谢谢了

秋水时至

对啊，代码要贴完整才好嘛。。

顶一个，Good！

就是个坑啊~
