Re: TNC-Pi9k6 firmware
No, the TNC can use i2c for communication, but you have to configure it in the firmware, you can't change it with pitnc_setparams.toggle quoted messageShow quoted text
To enable i2c remove HOSTPORT from TeensyConfigPacket.h. You can change the i2c address by changing the #define I2CSLAVEADDR

My understanding is I2C is just used for configuring the TNC but not for packet communication. I think there was a post regarding that a couple of months ago. If you want to stack multiple TNC-Pi9k6 you will need to grab a raspberry Pi 4 which has 6 UARTS and then connect them to the teensy. This shouldn't be two hard to do with some jumper wires.
