I recently purchased the ncs314-6 v.3.4 Arduino shield with the Raspberry Pi Astrpa v.2.1 adapter. After setting up the Pi per the instructions, the tubes do not display anything other than a quick flash once powered on.
In reading others posts, I tried a larger power supply, which did not change anything. I then resurrected an old Arduino Uno and that worked just fine and the clock worked as intended. Are there any suggestions for troubleshooting the Arduino – Pi adapter board, or ways to verify that the software has been installed correctly? Thanks!
