Hi,
I have firmware 1.2.2 and have pulled and reinstalled the latest grovepi release but i found the 4 digit display to behave very strangely. It is easier if you see the “stock” script in action (i only changed display = 6) https://vid.me/DtM8
I tried manually outputting simple numbers, scores etc. but it works in a very “fuzzy” way… any clue?
