I’ve just started using the PT2 smart io module and have run into the following:
I followed the instructions here: https://github.com/groupgets/purethermal1-firmware/tree/development and did a make USART_DEBUG=1. This seems to work as some extra statements print out telling me USART_DEBUG_SPEED=115200. I convert my main.bin to a dfu and flash the PT2 board with it. No errors. I’ve connected a usb to ttl convertor (which I’ve verified working on a different board) to RX,TX and GND on the PT2. I never see any data coming out. I checked on the scope, don’t see anything. I know this must be something dumb, but I can’t figure it out. Any help would be appreciated.
