openmv输出与stm32的接收没有连接上是怎么回事呢?
-
连接的是P4或P5都可以对吗?为什么连接的stm32但是用UP_ADC_GetIO()无法接收到openmv输出的0与1呢?

OpenMV用的uart发送,stm32就要用uart接收。
你用stm32的adc连接OpenMV的uart?
-
那麻烦问一下openmv用ADC需要怎么输出串口信号呢?谢谢
-
@nglk 你具体是什么意思?
ADC和UART完全不是一个东西。

@kidswong999 就是不知道基于keil的stm32单片机怎么接收openmv用uart发送的0和1

控制stm的uart的就行。具体如何操作需要看stm32的教程。
