Don’t you need bidirectional signals to make good use of the controller for this display? Because this display look pretty similar to the display i have based on the ILI9320 controller.
The pcb beneath the dispay is forcing me to use the 16bit parallel mode of the 1298 controller. i could read out data from the diplay, but i had no reason to do it yet.
i am not capable of getting the display to work in 8bit mode. i can’t find the fault and it is driving me mad. they mouted a 74HC573 latch on the pcb to use the 16bit mode with 8 bit input, instead of making it possible to enable the nativ 8bit mode of controller.
Yes that looks exactly the same as the ILI9320 based displays that we bought Shuriken.
I did manage to get a MIOS32 driver written and working for it in 8-bit mode but since then I have had a bit of a crash and I think I lost the source code
If I remember correctly, the key to getting 8-bit mode working was that you place the LE pin high then load the lower 8 bits onto DB08-DB15 and then set LE low and load the upper 8 bits. the transition of low to high latches the current state of the inputs on the 74HC573 (DB08-DB15) and outputs them to DB00-DB07, this has the effect of loading all 16 bits to the display, you can then pulse the clock.
Cheers

EDIT: Also DO NOT tie the unused DB00-DB07 inputs to ground, they MUST be left floating as otherwise it won’t work in 8bit mode!
I recently got this display one from mouser. Which can be driven via SPI (48Mhz). At about same price. Hopefully a lot faster. Haven’t fired it up though.
