I am relatively new to the world of microcontrollers but have had a little bit of experience with displays as I have cobbled together / adapted a driver for an ili9341 adafruit SPI display.
Moving on from this I have my sights set a bit higher but want to check whether what I am thinking is possible and if anyone has any of the information I can't find.
I am looking to use a round AMOLED display with an ESP32 and have found 2 basic options (with a 3rd that is slightly different). I have found some displays based on an RM69330 display driver (such as this: https://www.alibaba.com/product-detail/1-39-inch-ips-454x454-rohs_62286293416.html ) which seems to support MIPI and SPI, which seems to be backed up by the vague pinouts I have seen that have SPI labled pins. The other lookks to be driven by an RM69080 display driver that only appears to have MIPI pinouts and so wouldn't be suitable to be used with an ESP32. As another option there is something like this larger screen that appears to support SPI/RGB: https://www.szmaclight.com/product/round-lcd-display-2-1-tft-480x480-RGB.html
One problem I am running into is that I cannot find a datasheet for the RM69330, or any written drivers, which would make it very difficult to use the screen.
Additionally I am not sure what I would need to plan in terms of additional components (resistors, capacitors, etc.) to use the screen as I assume they would be needed.
Does any one have any experience with any of these screens or know of anywhere with a write up or code detailing them?
Thanks in advance for any advice you might have.
