// On my Maithoga ILI9486L display (https://www.aliexpress.com/item/3-5-inch-8P-SPI-TFT-LCD-Color-Screen-Module-ILI9486-Drive-IC-320-480-RGB/32828284227.html), the following speed settings have been tested:
|
|
|
|
// core_freq=400: CDIV=8, results in 50.00MHz, works
|
|
// core_freq=400: CDIV=6, would result in 66.666MHz, but this is too fast for the display, and produces corrupted output
|
|
// core_freq=305: CDIV=6, would result in 50.833MHz, but this would work most of the time, producing occassional corrupted pixels
