Good morning everyone,
I'm developing a firmware for a machine. This machine has 5 PT100 temperature sensors and I use a MAX485 board to communicate with two PTA8C04 boards to read their signals.
Initially, I developed the firmware on an Arduino Mega 2560 board and everything worked fine. However, considering the needed computational power for all the stuff in the machine, I changed it to a GIGA board, and now the communication with the MAX485 board doesn't work.
To communicate with the MAX485 board I use the Giga Serial1 (RX D0, TX D1) with 9600 baudrate. Has someone some experience with this combination of boards and has a solution?
I don't know if the problem is related to the fact that Serial1-4 are unbuffered, as it seems from these post serialx-x-1-4-are-unbuffered-surprised
Thank you
