Hi everyone,
I have a problem: I'm trying to use an ESP32 to display stuff. But it tells me here

SPI_send(this->EPD_Pin_EPD_CS, CU8(0x70, 0x02), 2);
SPI_send(this->EPD_Pin_EPD_CS, CU8(0x72, 0x40), 2);
// check breakage
SPI_send(this->EPD_Pin_EPD_CS, CU8(0x70, 0x0f), 2);
int broken_panel = SPI_read(this->EPD_Pin_EPD_CS, CU8(0x73, 0x00), 2);
if (0x00 == (0x80 & broken_panel)) {
this->status = EPD_PANEL_BROKEN;
this->power_off();
return;
}

that my display is broken, but if I use the PaPiRus demo, the Display works fine... Do you have any idea what could be the cause?

Thank you!

@Donderda Can you try to skip this "check breakage" ?
We have a signal trace surrounding the TFT glass and it can sense the glass breakage. Sometimes the signal trace is damaged but the AA(active area) is not.
