You are correct about the SPI bus using CS. I have to add extra code to select the correct module via GPIO.
some modules have active high and other have active low CS and they also may have different bitrate. ofcourse I can manage this with correct logic
Maybe one more point to ask so I can conclude on this topic:
There was a good hint mentioned in the topic regarding using PIO for UART. This will allow 6 UARTS ( 2 physical + 4 via PIO).
I was thinking that Pi Pico can play as UART_MUX. i.e, one UART is talking to the Pi 4 and can select between 5 UARTs to talk with.
would that be good idea ?
