SPI and I2C Together Trinket M0

Post by Frank_B »

Hi, I need to use a sensor that operates in I2C and have an SD Card the operates in SPI store the data from the sensor. I noticed that Pin 2 on the Trinket M0 has a dual function as SCL for I2C and MISO for SPI. Is there a way to have a component operate in SPI while using I2C with this board?

I don't believe so. Pins are very limited on the Trinket. To keep it small you could switch to the SAMD21 version of the QTPY which gives you more pins, including separate I2C and SPI.
