Turns out the baud rate was wrong and I should have figured that out from the waveform. I used the automatic baud rate detection feature. HardwareSerial pump(2); #define TXD 17 #define RXD 16 char lastByte = 0; char inByte = 0; int count = 0; void setup() { // initialize both serial ports: Serial.be...

Thanks for replying! It's appreciated. I made some changes to the code as suggested, but I'm still just getting "0000" zeros. HardwareSerial pump(2); #define TXD 17 #define RXD 16 char lastByte = 0; char inByte = 0; int count = 0; void setup() { // initialize both serial ports: Serial.begin(115200);...

Hi, First time working with the ESP32 and interfacing with RS485. I'm using this shield with a M3485 chip. https://www.electrodragon.com/product/esp32-can-rs-485-wire-interface-shield/ For now, I'm just trying to receive data over the RS485 interface and echo it to the serial monitor. #define TXD 17...
