I would like to connect a LCD 320x240 to the DM365. The LCD have a clock rate between 6.5 MHz and 10 MHz.
Datasheet of the LCD:
3286.3.5-GVTQ35SNAD3E0_REV_A_-20100927_32I0N4T89.PDF
The first section shows the LCD with 27MHz. The size is ok, but the clock rate is to high.
The second section shows the LCD with 6.5MHz. Clock rate is ok, but the image is to small (quarter).
So i set the following register to get 6.75MHz (27MHz / 4):
VENC_DCLKCTL 0x00000064 0x00000003
VENC_DCLKPTN0 0x00000068 0x0000000c
I also adapted (multiplied by 4) HSPLS, HINT, HSTART, and HVALID.
Anything else to do? Where is my mistake?
Thanks
Size OK, clock rate to high
