@modos This is *very* interesting— question— your devkit is relatively expensive compared to a basic microcontroller— do you believe this devkit is set up such that it could potentially be connected to / drive multiple epaper displays at once?

Hi @mcc

If you want to drive multiple screens at the same time, it depends on the screen and data width.

The board has a 24-bit bus, so you can configure it as:

- One 16-bit screen and one 8-bit screen
- Three 8-bit screens

If the screens don’t need to be driven simultaneously, you can add buffer chips and chain more screens.

In that setup, you multiplex them and only drive one at a time.

This requires extra I/O, which is available on the board but not supported in the current firmware.
