SPI slave and I2C slave for SAMD51 boards #2225

Closed jstanle1 closed 4 years ago

jstanle1 commented 4 years ago

Please implement SPI slave and I2C slave for the SAMD51 and SAMD21 boards. The SPI slave would benefit from being implemented using DMA, as well.

Thanks.

It's already implemented, but not turned on on the sAMD21 boards due to lack of space. You could turn it on and turn something else off. It's controlled by the CIRCUITPY_I2CSLAVE value, which you can set in mpconfigboard.mk. E.g., look at ports/atmel-samd/boards/feather_m0_express/mpconfigboard.mk

Dan -- thanks very much for you replies. Any word on whether this might work for the SAMD51 boards?

dhalbert commented 4 years ago

This was indeed tested on SAMD51 boards when the PR was done: https://github.com/adafruit/circuitpython/pull/1064#issuecomment-410435059. It is included in the SAMD51 builds.
