Paneldue 7" with esp32/raspberry pi
-
Hi. I have a Paneldue 7" display with Atmel ATSAM4S4B with SSD1963 and XPT2046. It has the paneldue firmware already in it. I want to use this display for other purposes, not just as a display for 3D printer. Since it has an SSD1963 and XPT2046, it feels like a TFT display, except it has a processor in it. I want to hookup this display along with esp32/Raspberry pi to upload images or use it for other purposes. Is there any workaround for this? Libraries to connect esp32 with Atmel onboard processor? Methods to flash custom firmware on it? Can I upload code with Tx/Rx or SPi bypassing the processor? Please help me out with this.

@Candy This is a clone of the Duet3D PanelDue, which we don't support here. Unfortunately the PanelDue is not Open Source (it was not designed in-house by Duet3D) so we don't have any more information on how the hardware is designed.
That said, it sounds like a lot of work to rewrite the firmware to interface the Atmel with an ESP32, particularly when it will limit the display capability (ie, text only). Probably better to find an ESP32 breakout board to connect the ESP and TFT without the Atmel in the middle. Then you could develop a UI in lvgl.io . Look at similar screens from Elecrow or MakerFabs, they're not that expensive.
