testnRFi2c

Testing i2c communciation between the nRF52840-mdk board (running the Rust nRF52840_hal) and the AT88CKSCKTSOIC-XPRO (Microchip XPRO) extension board.

• Picture below contains the following:
  • The AT88CKSCKTSOIC-XPRO (Microchip XPRO) extension board (the one in red to the left)
  • The extension board is just a passthrough that connects the actual i2c slave via a SOIC port (i.e. the black contraption on the red board).
  • The nRF52840-mdk board running our example code (testnRFi2c).

    • Unable to transfer 2 zero bytes. The TWIM peripheral's AMOUNT register reports no bytes were sent.
