With the ESP32 you can decide which pins are UART,I2C, orSPI– you just need to set that on the code. This is possible due to the ESP32 chip’s multiplexing feature that allows to assign multiple functions to the same pin. If you don’t set them on the code, the pins will be c...
On completion of transaction, ESP peripheral pulls Handshake pin low. If completed transaction had a valid TX buffer, then it also pulls Data ready pin low. gpio_hand_shake: handshake拉高,表示esp32端装载了一个接受或者发送buf,然后host端检测handshake是高,就可以发送数据了,esp32在spi传输数据的时候...
