Integration and connection of the E-ink screen

Personal 56 USD

Oleksandr successfully completed the task, despite the fact that the task turned out to be much more complex than expected.

During the work, significant difficulties arose, as the manufacturer sent a board with the wrong firmware, and there was no ready driver that would work with this screen size and our configuration. After correspondence with the manufacturer, Oleksandr decided to reflash the board himself and write the driver almost from scratch, which he successfully did.
