Hello,
i'm running touchgf in my 720x720 18bit display. I need to decrease the fps because of the heavy rendering time.
I know that to decrease the refresh rate i need to change the LTDC clock frequency. Now it is working with 25MHz (which should be approximately 50Hz). I know also that i need to change the porch timings when i decrease the TFT frequency.
Actually they are:
HSW = 20
HBP = 20
Active Width = 720
HFP = 10
VSH = 10
VBP = 10
Active Height= 720
VFP = 10
My question is how much i need to decrease each value to get 25Hz frame rate? I kown that i have to change the TFT clock to 13MHz, but what about porch timings?
