GFX library in C for Nordic processor

by jperrin on Mon Mar 12, 2018 12:16 pm

Hi I purchased the 1.8" Color TFT LCD display with MicroSD Card Breakout - ST7735R. We are integrating this part into our current product. Our current codebase is based on the Nordic NRF Arm M4 processor in C. We are trying to convert the GFX library and some of the underlying controller libraries to C. We understand we will have to customize the SPI driver library, and hope to just use the HX??? controller library and GFX library.

Do you currently have a C version of the GFX library - not C++? This will help integrate the component easier.

Our libraries are written for the Arduino IDE or in Python and we don't have c versions. Someone out there may have done this or you may find a "translator" program that could do most of the work.

Could you point where to start to port the library? I'm working with a NXP LPC1788 and I'm planning to use the 3.5'' TFT so I will need to port GFX and TFTLCD libraries.

Thanks!
Mariano.

I would try the NXP groups and whatever compiler package you are using.
