Simultaneously Receive from Two UARTs

Postby joshbillions » Sun Jan 20, 2013 3:33 am

I'm debugging a GSM modem and am looking for a way to configure the Bus Pirate to listen to communications between an Atmega328P and the modem in both directions. I currently use the UART Rx pin on the Bus Pirate to listen to message from the Atmega to the modem, and a second Arduino to listen to messages being sent back to the Arduino from the modem. Is it possible to configure the Bus Pirate to receive UART messages on two pins?

Sorry, not in v3. v3 only has 2 hardware UARTs and one is assigned to the user side while the other is used for the IO header.

Technically it could be possible to reassign the input from the user side to the IO header, but that needs a bunch of updates to the code base and you'd never be able to leave that mode.

If the software were there, could the v4 board support this correctly?

Technicaly it should, but it's not implemented in the firmware yet.. Probably use the AUX 1 and AUX 2 pins as the second UART
best regards FIlip.
