Hi, I just installed a new display-o-tron hat on a raspberry pi 3b running raspbian stretch lite, and I can get the backlight and bar graphs to work, but not the text. I have searched the forums here and already checked that we are running dothat examples and imports, not dot3k, and that i2c and spi are both enabled in the config file. We have also updated the pi and adjusted the contrast on the lcd to no avail.
What else should we try? Running sample code, the bar graph and backlight seems to be working perfectly. The text examples don’t display text, and following simple code does nothing:
from dothat import lcd
What next? Thanks!
