ILI9488: pixel queue size limited?
Posted: Tue Dec 17, 2024 5:24 pm
I’m using an ILI9488 SPI display with an ESP32_WROOM board.
One of the display settings involves the "queue fast pixels" option, which requires specifying the pixel queue size. I believe this is set to 300 by default. However, whenever I try to increase the pixel queue size, the display behaves oddly.
The background displays a strange color, and the text and numbers I print on the display seem to use the background color that I had previously set with SetBackGroundColor.
Could this be a bug in the program? Or is it a hardware limitation of the ESP32?
How can I determine the maximum allowable size for the pixel queue?
I want to render information on the display as quickly as possible. Since the SPI speed is limited to 32 MHz in this case, the queue seems to be my only viable option for now.
