HY28B in 16 bits parallel mode
Hi Frank !
Is your SPI_TFT_ILI9320 Library can drive the newest HY28B in 16 bits parallel mode ? (I have a HAOYU Mini-DK2 with HY28B, and I wish to keep speed efficency of the 16 bits more)
Regards,

Hi Martin,
Unfortunately, this library only suports SPI mode.
Adding 16-bit parallel mode is on my todo list but, currently, i can't tell when it will be implemented.
Hi Frank, Thanks for the info. If you need to access to chinese sources I've got from the manufacturer, I can provided it to you (although is quite ugly, especially the touchscreen part that I didn't manage to get working properly).
posted by 07 Jan 2015Thanks, but i already have these sources. I think it will be much easier to start with the current mbed library and replace all LCD SPI code with parallel bus code.
posted by 07 Jan 2015Edit - i started creating a forked lib using 8/16 bit parallel mode. If time permits, this should be finished this weekend.
Note : I will try to include 2 bus options - one using BusInOut (freedom of pin choice - not the fastest) and one using PortInOut (limited pin choice - faster throughput).
Update
There already is a 16-bit parallel library available for the ILI9325 (and other LCDs) at this page.
This was ported from Hennig Karlsen's UTFT library.
Yet another update
The 8/16 bit addition is put on hold - i started a topic about what needs to be done to make it easier for future TFT library developments.
Hi Frank, Thanks for the hint, I didn't know that there was already a Library for 16bits. I gave it a try, it seems to work, except few minor glitches like all RGB are inverted and it seems that full ClearScreen is a bit slow. I will investigate. At least, it is better than the chinese code. :-)
