Putc routine ignoring input X and Y positions

Also ignored / deleted ancilliary files

Thanks for that. I made an update here, and also in my LTDC library for this LCD.

Thanks again!

Hi Tilen

Thanks for all the work you have been doing on your libraries. They are VERY helpful.

I made a git that, when laid over the top of your project, allows it to be compiled / flashed from GNU linux. I can't afford the Kiel full version, and my projects are starting to be too big to compile with the free version.

Feel free to use it.

If you are looking for another project, I want to make the touchscreen / gyroscope work via interrupts. That is my weekend project. If I get it working, I will submit a pull request to you.

Also, the diagonal line drawing algorithm is broken. (straight lines work, that is why boxes work).

Warmly Dennis

I'm using Keil, but libraries also work in GCC free compiler.

Well, for interrupt you need only to set corresponding pin for it in exti vector table and enable nvic. If you don't know how to enable external interrupt, I have a tutorial for this. http://stm32f4-discovery.com/2014/08/stm32f4-external-interrupts-tutorial/

Yes, thanks, I am very happy that the library works on GCC.

Thanks for the tutorial.

Cheers Dennis

Hi Tilen

I rewrote the line drawing routines. The old routine would not draw diagonal lines, and I needed them. This implementation is also a bit simpler.

This probably also applies to the ltdc routines. See below:

void TM_ILI9341_DrawLine(uint16_t x0, uint16_t y0, uint16_t x1, uint16_t y1, uint16_t color) {

int dx ; int dy ; int sx ; int sy ; int err ; int e2; dx = x0<x1 ? x1-x0 : x0-x1; dy = y0<y1 ? y1-y0 : y0-y1; sx = x0<x1 ? 1 : -1; sy = y0<y1 ? 1 : -1; err = (dx>dy ? dx : -dy)/2;

for(;;){ TM_ILI9341_DrawPixel(x0,y0, color); if (x0==x1 && y0==y1) break; e2 = err; if (e2 >-dx) { err -= dy; x0 += sx; } if (e2 < dy) { err += dx; y0 += sy; } } }

Thats great. I will test and add code if it works properly. Thanks.

[MaJerle]

OK, I fixed this now. It works great. I also made your nickname in comment in function.

Thanks for code.

[dewoller]

I thank you! I would be lost without your work.
