Hanshow 420Q e-Ink Display Driver #70

Description

@calbertoli

Apologies if this isn't the right thread for this, but for the Hanshow Nebular Pro 420Q I was wondering if anyone has the actual display panel drivers used by the board to update the quad-color e-paper display. Could probably use the contact pins to log waveform sequences, but was wondering if anyone has saved drivers like others have for the Vusion series ESLs.

The smaller ones have their display ribbons fused to the board, but the 4.2 one uses a 24-pin connection adapter like the Vusion family. Working on a Pico runtime that uses ESL displays, so far the 4.2 Vusion is working but I'd like to give my Hanshow display a try too.
