STM32HAL库 SPI主从机通信1.简介SPI可以实现全双工通信,分为主器件和从器件,主器件发起时钟控制通信的开始和结束,从器件只能被动等待住器件发起通信。如果主器件一直不发起通信,没有时钟产生,从器件是没办法发送数据的,只有主器件产生了时钟之后从器件才能将寄存器中的数据移位发送出来。SPI有4中通信格式,实验采用的平...

I'm trying to get data from esp32 by a spi connection. Esp32 is the slave and a texas msp430 is the master. Esp32 firmware is the example SPI-slave in the idf examples. When the master requires for the data the esp32 returns data and after gets this error: Code: Select all Guru...
