New CANPico firmware released
We’ve pushed a new version of the CANPico firmware that
updates it to MicroPython v1.16.
The update also fixes some bugs but the biggest change is that the
firmware adds robustness to SPI noise: it’s very easy to accidentally
cause the SPI pins to pick up noise from logic analyzer probes where
the logic analyzer isn’t grounded, and corrupted values written to or
read from the CAN controller can cause things to go crazy. The firmware
keeps counters for the number of times corrupted values with a new
The documentation has been updated to reflect the new API call, and
there is a new version of the
canpico.py file of example functions
that are useful when trying out different things on the CANPico board.
