Hi!
I have worked on a project for a while with an Ili9488 and an ESP 32, before Ben has made the Highspeed 80 mhz prescaler. The display has been fairly fast with the pin config I use in this project, up to 30 mhz working ok.
Now I have program the device again, not change anything, but now the display is suddently extremly slow
I have a backup backup try to program this also, same.
I started the project in FC9 and continue in FC10 all work until now. I try to program with FC9 (older) then it is fast.
Just like prescaler is on 6mhz.
please could this be fixed back again??
A project I have had a pcb manufactured for and spent many hours on this project, so not easy to change to the highspeed SPI

Re: After update!
To be honest I've noticed the same with a Pic16f18877 project that i've been working on. Timing seems to be way off at 32Mhz. approx 4 seconds on a 1 second delay
Edit - sorry i should have said 'in hardware'

Hi Wingnut
Four seconds on a one second delay sounds a bit PLL related. Is/Isn't 4xPLL enabled when it should / shouldn't?
I'd have a look at those as it's very easy to overlook in the configs.

Hi again!
@wingnut I don´t know what happen with your project and your device, but mine is for ESP32 dev and the ILI displays.
Trying to investergate to get my old project to run again. I have perform some test The Ili9488 ESP32 SPI High Speed Modes is also slow.
The Ili 9341 and the ST7796 working still inESP32 SPI High Speed Modes, but slow if i not use high speed they are very slow.
Concerning my project which file do I have to roll back so I at least can try to finish my project, is it file for the display or the Esp32, please?

Hi Jorgen,
The display component has new properties specific to the esp32. Make sure the fast pixels property is set to yes and give a generous buffer size. Maybe 40 or 80. Hopefully the display will be much faster than it was before.
