Hey. I would like to clarify something regarding the USART on the raspberry pi 4. I have connected a stationary barcode scanner to one of the USB ports and it appeared as ttyACM0 on my raspberry PI. I am able to send serial commands and everything seems to be working as expected. I am assuming that ACM0, 0 at the end means that it is connected to USART0?
I want to connect to a RS485 driver to my raspberry PI and communicate with other modbus slaves. Assuming that USART0 is already occupied by my scanner , I need to connect my RS485 driver to any other USART?
The problem is that I was able to find little to none information on how to implemented and activate USART2, 3, 4 peripherals on Raspberry PI. Have anyone else got any experience on that and would be able to share some information?
