I’m trying to connect my feather M0 to a “digi dot booster” which is an LED controller that communicates over SPI.
The device comes with a library (https://github.com/Gamadril/DD-Booster-Library) that lets you send simple commands to get complex colour displays.
Using the example sketches and an Arduino Uno, everything worked as expected. Now I’ve switched over to the feather, I can’t get the communication to initialise. I’ve changed the CS pin, as the default on the feather is linked to the BLE module. Ive tried doing this via the library command and manually, to no avail. I’ve also tried laying with the SPI initialisation settings to see if that makes a difference.
By using “raw” commands and not resorting to anything from the library, I’ve been able to change LED colours, so I know my connections are good, but obviously would like to make things simpler by using the library!
Any help would be really appreciated!
