Hi recently I have been working on TFT INI9341 and facing problem with displaying bmp images on TFT screens. Library that I used is https://www.hackster.io/rayburne/psoc-4-using-the-color-glcd-ili9341-8c92f5 and it works perfectly fine for other things, but in case of displaying bmp its behaving bit weired, I spent entire day figuring out strange behaviour. Either I am using wrong converter which is http://hobby-research.at.ua/load/utility/grafika/bitmap2code/9-1-0-22 or there is something else. I get very weiredo image on display,, half here half there. Also attaching BMP image along with the library. I don't know whats wrong there. I think it is converter. If anybody here was able to display a bmp successfully
1) What convertor do you use ? I can smell there is some issue with my convertor. Bitmap2code link already shared
2) How you were able to display ?

Hello Bob thanks for conversion, but I use 16 bpp and that option was not available in LCD assistant. Regarding your LCD program, now I am able to find problem area in my case. Its with BMP2C convertor. How I find it that is interesting. I was seeing a pattern int the image displayed after convertion. In that image was filling in a pattern like it was devviding rectangle into half by diagonals and first filling X-axis on right side of line then left. I wrote a basic C code and re-arranged the array as shown below and now its working. It is not a permanent solution just temporary one, to find the problem area. And BMP2C converter is problem area here (don't know why it is converting like that. I wasted my entire day downloading different converters. Tomorrow I will write my own BMP2C converter application. Till then if anybody faces similar problem he/she can use this code.
#define X_AXIS 50
#define Y_AXIS 50
void RearrangeArray()
{
uint16 u16xx, u16yy,u16Index,u16Actual=0, u16array[2500];
u16xx=X_AXIS-1;
for(u16yy=0; u16yy < Y_AXIS; u16yy++)
{
for(u16Index=u16xx; u16Index< X_AXIS; u16Index++)
{
u16array[u16Actual]=ImageArray[u16yy][u16Index];
u16Actual++;
}
for(u16Index=0; u16Index< u16xx; u16Index++)
{
u16array[u16Actual]=ImageArray[u16yy][u16Index];
u16Actual++;
}
u16xx--;
}
TFT_FillBitmap(50, 100, 50,100, (unsigned short *) u16array);
}
Converted my imageArray [2500] to 2-d array as ImageArray[50][50];
PS - This is a temporary solution to check library.
