PyBoard LCD160CR Text Scrolling Window 8

1

I used my PyBoard microcontroller + LCD160CD screen as a name tag at 44CON.

I had to do some research, as I could not find example code to get the text scrolling working. The key to the solution was to set the direction to 2 (-x).

This is the code I put in main.py:
