ILI9341 slow work

Post by maharadga »

Hello.
I try module TJCTM24024-SPI with ILI9341 controller. I see that display work very-very slow. My frequency is 32MHz.
Is this normal or not?
I attach simple programm.

Hi,
I see in the configuration you are using HS-PLL enabled.
I don't have the same PIC but I used 18LF26K80 time ago to write in similar display and to enable PLL I had to use a C block at beginning of the flowchart like:

OSCCON = 0b01110000;
OSCTUNE = 0b01000000;

Check in the datasheet the right values and registers for your PIC, maybe this is the problem.

Regards
Giuseppe
