I’m setting up a Seeed RS485 pressure sensor on the dev board and monitoring the output through PuTTY with my laptop connected via the USB-C port on the Mote. However, PuTTY is reporting a serial communication error for reasons currently unknown. I’d like to verify what signal is reaching the STM microcontroller when the error occurs.
@jaszylu, you can find the schematics for the mote and bristlefin (orange board) here.
The following screen capture shows the pins on the MCU:
PA2(pin 12) and PA3(pin 13) are the TX/RC lines
I would recommend reading this guide. Specifically the section, Physically integrate the sensor which explains some of the jumpers that must be set for RS485 integration.:
Let me know how else I can help!
