Hi all, I have the following strange problem. I am working on the ILI9341 library and the graphics was staring to work but I could not manage to write text to the screen. When I tried that the PIC went haywire and sometimes came into some kind of constant reset state.
By accident I discovered that it had to do with the size of the program. In the program I include a picture. When I do that the program size changes from 5k to 21k bytes. If I do not include the picture, printing text goes OK but when including the picture the PIC goes haywire again. If I leave out the printing of text and include only the graphics with the picture then all is well. When I look at the assembly, there is a piece of code used for printing fonts (using pixels) that uses multiplication. If I look at that piece of code in the asm file the code for multiplication is different. In the attached screenshot you see the code that goes wrong on the left and the code that goes right on the right. Has anybody experience this kind of problem before so having problems with a large program in combination with multiplication (I may draw the wrong conclusion here). Any suggestions? Hopefully it is not a compiler issue :-( Thanks Kind regards, Rob -- You received this message because you are subscribed to the Google Groups "jallib" group.
