[Question] Streaming to IT8951 #6

First I would like to thank you for this.

After countless hours of trying and searching around I was finally able to show something on my 9.7 inches e-ink display.

I'm actually trying to fetch an endpoint that returns a bmp image on full resolution and display it on the screen. I guess ESP32 does not have enough memory to handle that. I saw you mentioning that it's possible to send it to the IT8951.

Do you have any pointers on how to do that? Any sample code? Any hint is appreciated.

Call IT8951_Load_Begin and LCDWaitForReady. Then call bcm2835_spi_transfer for every few pixels that you fetched from your endpoint.

Anyways, nowadays the easiest way is just to just get an ESP that has additional RAM.
