3_Basic_partial_update example for e-radionica Inkplate 6
For this example you will need only USB cable and Inkplate 6
Select "Inkplate 6(ESP32)" from Tools -> Board menu.
Don't have "Inkplate 6(ESP32)" option? Follow our tutorial and add it:
https://e-radionica.com/en/blog/add-inkplate-6-to-arduino-ide/
In this example we will show how to use partial update functionality of Inkplate 6 e-paper display.
It will scroll text that is saved in char array
NOTE: Partial update is only available on 1 Bit mode (Monochrome) and it is not recommended to use it on first refresh after power up.
It is recommended to do a full refresh every 5-10 partial refresh to maintain good picture quality.
