df_flying 发表于 2016-4-27 08:44 应该是电路问题，F4的硬件IIC还是比较好用的 硬件电路应该没问题的，是开发板
lulongqin 发表于 2016-5-9 10:33 我用了HAL_I2C_Mem_Read和HAL_I2C_Mem_Write，但是也没能测试通过，现在还在找原因 ... 好好找找吧，反正我一直用得挺好，都不用自己管发送地址发送开始位这些了
Paderboy 发表于 2016-4-20 20:56 刚好有这个板子。。。做了个工程，开了4个ADC 通道， PA0 PA1 内部温度和内部参考电压通道。。 测试结果 为啥我的STM32CUBE输出的代码那么乱，兄弟能告诉我嘛？你自己整理过的？
