Knomi round screen
-
is it possible to use the knomi with the duet? It is a round screen designed for the voron and klipper compatible.
I've noticed that it is powered by an esp32.
If I'm not wrong I can connect an esp32 to the duet bord (the panel due pin urxd0 and utxde0 3.3v and gnd) to keep some info such as temperature and print time, and using Bluetooth I can connect to the knomi with a custom firmware for it that read the Bluetooth info and then update the screen.
Do you think it is possible? -
@Lakko you'd need to modify the firmware. Currently its set to work with the moonraker SPI which won't work with RRF
-
@jay_s_uk yes, it will be a custom firmware for the esp32 on the knomi but I think it won't be to complicated (I've made some other project with esp32 using ble).
My biggest concern is how to get the data I need trough the panel due pin. -
@Lakko you don't use the paneldue pins, it uses wifi
