I'm new to this and i'm having the hardest time getting readings from the accelerometer when I have data going to the OLED. None of my pins are crossing so I'm not really sure the issue. Both are using SPI but I've assigned all their own pins.
I'm using an adafruit LIS3DH as well as a sparkfun micro oled breakout
Does something in my testing code look off? Is there a better way to approach this?
