I am using a tinyscreen+ with the IMU 9dof and SD card reader stacked together. Tried both the SD card info and the datalogger example (after setting the pin to 10). I am not getting any output at all. The serial baud rate is set to 9600. I send over a string to start, but getting no output back. Is there something additional needed to make the example work with the Tinyscreen+ over the traditional Tinyduino?
