LPC4088 Emwin 24bpp is it even possible?

Hi Everyone

I am trying to connect a TFT screen via a parrallel RGB interface, seems simple right?

The LPC4088 in 24 bit RGB only uses 3 out 4 byte of DMA RAM (wasting 1 byte)

I could not find any driver mode that work in emwin that allows this. ALL the linear drivers seem to remove this wasted byte:

Only a driver GUIDRV_S1D13513 that is build for the Epson S1D13C00 seems to do that but that seems to be device specific:

So is there a way around this?

Thanks for your time

Remi

Unfortunately, no. It is by design that the 24-bit RGB only uses 3 out 4 bytes of DMA RAM on the LPC4088, so it cannot be changed.
