latigid on Posted April 28, 2017 Report Share Posted April 28, 2017 For completion's sake, did you get the ST7066U LCD working? Btw, these threads aren't a waste of time, as there's a lot of good troubleshooting tips. Could be a useful entry for the wiki? Quote Link to comment Share on other sites More sharing options...
