I figured out some things by myself. I found that the uart registers are accessible through the uart struct provided in soc/uart_struct.h. #include "soc/uart_struct.h" ... UART2.rs485_conf.rx_busy_tx_en = 0; //0 => enable hardware arbitration ... Answer to Q3: I found that by setting the mode of the...

I’m new to the forum and hope to find some support here. I want to use an esp32 as a node in a 485 bus with the following conditions: baudrate: 921600 bits/sec no master slave, so all nodes can send at all times inter frame delay >= 10bytes ~ 100us addressed nodes are sending a 1byte acknowledge wit...
