I'm trying to get serial feedback from a device. Does anyone know where on the V4 I should attach to read back serial information from device? I know I send a serial command to through one of V4's digital signal pins but where do I read it back from?
I thought it would be read from the same digital pin I sent the command. However @Toymaker made a comment in another thread that it may have to be read through one of the i2c ports.
Any insight is welcomed.
