Ideas for improving LCD speed

I am talking about obtaining performance similar to that of the Luckfox Lyra, not 60fps. I read somewhere that the ILI9488 can run at 40MHz.

I reviewed the micropython port code about SPI…

Yes, it seem to be init with 40 MHz, but for the same reason I’ve noticed you at the first post, I think the 40 MHz “requested” is in fact the default one (25 MHz).

To check if the 40 MHz is reached, there is two ways:

• check the clock signal with an oscilloscope,
• look at the value returned by the spi_init() function.

Ideas for improving LCD speed

From my testing on the Lyra average fps is around 45fps. But Hispoot who made the cfw has released another LCD driver that should improve refresh rate i have yet to test it. new screen driver for testing. It uses rgb565 mode by default, instead of rgb666 mode, and can use 3bit mode by passing p_3bit_mode=1 p_dither=1 or p_3bit_mode=1 p_dither=0 If you want high refresh rate, you can try 3bit mode.

I should look at it!
