Why don't you just use the existing TFT linux driver?

I'm pursuing the same so let's share progress!

As I mentioned in the other thread, my TFT is not on the compatibility list.
I was also using manual bitbang SPI as the alpha boards didn't have the SPI broken out. Now I have a release board and a new supported LCD on the way from ebay I will use that library and normal SPI. I intend to get the touchscreen working too.

how difficult would that be to use with something like this lets say? http://www.ebay.com/itm/SPI-1-5-Color-O ... 1e7212fbc8

also is this using directfb at all? I'm a bit confused as to what's happening. Could you use directfb on the vocore?

That is one cute little display! Very expensive for the size though.

If it isn't on the compatible list for the fbtft stuff then you will have to do the hard work yourself. It's possible to take a similar driver and modify it to run that display. If you do so please submit it back to the people running that project to include.

I bought my new LCD because it was
1) Cheap
2) easily available from lots of suppliers
3) Supported by the fbtft drivers.

Search for ILI9341 320x240 on eBay and there are lots. It's only small but it has SD socket and touch on board normally too.
