When initiating transmission, the original ArduinoModbus library (which is designed for a specific Arduino shield and uses RS485 class as UART-to-RS485 abstraction) applies hardcoded 50us delay regardless of port speed, which resulted in garbled communication over RS485 in a setup with generic RS485-to-UART module based on MAX485 chip. The second UART is your tool to connect a terminal emulator to the Arduino and to send messages to the Arduino which are then transmitted over RS485 to the bus. Usage Using TCP or RS485 shields, like the MKR 485 Shield. // Only minor changes have been made such as the removal of the pointer allocation of Serial ports. * For example the Arduino MEGA 2560 */ PZEM017 pzem (&Serial3); void setup You signed in with another tab or window.
