pic32 ssd1963 16bit mode update available?

[ulrich.kuipers]

Hello together,
since three weeks i try to connect a fusion v7 board to a 7 inch tft with ssd1963 controller.
It works in 8 bit mode, so the connections seams ok.
But in 16 bit mode (TFT_init_ssd1603 (800,480) does not work ok.
The initialisation is not complete, timing?, declaration? setting gobal variables ...
I look for the discussions in internet, found some initialisation examples,
but there are limitations in simple commands.
In the TFT Library i found a remark that it is only for pic18-controllers. What about Pic32??
So, it seams since 2013 there were no further improvements in the tft-libs....

Hi Ulrich,
Could you tell me what display are you using?
Could you post the wirings?
There will be an update in the TFT library.
Kind regards
Petar

Hello, thank for the quick answer.
system: fusion V7 Board, pic32
Meanwhile i get Error message vom the mikro pro suite for pic v 2,5: writechip burst verify error...
Nothing changed?!? Going back the very basic... ledblinking... compling und prog ok, but result very slow, blinking change ca every 4 sec
check: oszillators: 80 Mhz, pll multiplier 20x, pll input devider 2x: seams ok, have no idea..
so I stopped development of tft drivers...

Hello I am back again.
Meanwhile i ordered a new processor the old was defective. That is the first time i have a defective mikrocontrolle on a mikroe board.
I soldered the old connections and the 7 inch tft is working in 16 bit mode. I can place text, rectangles and circles, but the colors are wrong.
There are no red colors, blue, white, green will be shown.

I modified the library _lib_tft_defs.c
- so it plot on the format 800 x 480

I think there is a wrong combination of the xx mit mode (command 0xb0)
and pixel mode (commando 0xf0)
and the routines in the library

Very interesting: there are tft_16bit in other mikroc compilers but not for mikroc pro for pic32!!
