Hi,

I want to interface the arduino uno tft lcd module 2.4" and 3.5" type
to pic uc, these modules use the parallel interface.
Is there any lib or c source available for pic?

Regards

Should not be that hard to port an Arduino lib to the PIC uC. All you need is to make sure that you have enough pins and enough RAM to fit the framebuffer into it + whatever you need for the processing.

try the CCS website, they have loads of code

http://www.ccsinfo.com/forum/viewforum.php?f=2

do search on tft

Also try the microchip forums.

best to search on the TFT controller number such as ILI9486, or  ST7783 or or  ILI9325 or SSD2119 etc


This link looks just what your after  http://www.ccsinfo.com/forum/viewtopic.php?t=50520&highlight=tft

Hi mars01

I have no experiance in c++, arduino libraries uses the c++ code,
is there any guidelines for converting the c++ code to c code.

Hi Wilksey

Yes this is the lcd I have.
In arduino software to use the 2.4" lcd the ID is 0x9325
for 3.5" lcd the ID is 0x9481
using mcufriends n adafruit graphics lib

it looks like it uses the ILI9325 or the ILI9481

try searching on them

I found this on the CCS site, there are 3 hits.

http://www.ccsinfo.com/forum/viewtopic.php?t=50520&highlight=ili9325

As I said in an earlier reply, the microchip forums will have discussions also
