Hi. the zumo shield took pins such as 9,10 for motor control so is it still okay to use SPI connection for sensor and such on the shield. Thank you.
In a previous post you mentioned using an A-Star 32U4 Prime with a Zumo shield. Are you still using the A-Star Prime? If so, the SPI pins on the ISP header are not connected to the rest of the digital pins like they are on an Arduino UNO (the A-Star 32U4 boards are more similar to the Arduino Leonardo).
By the way, you can find a diagram with the pinout for the board in the “A-Star 32U4 Prime pinout and components” section of the “A-Star 32U4 User’s Guide”, which is linked to on the “Resources” tab of the board’s product page.
