Buffer_Size in ILI9341_Draw_Colour_Burst() should be fixed

[bluenlive]

Thank you for your great work!

BTW, I think following line should be fixed
Buffer_Size = Size;
to
Buffer_Size = Size * 2;

It also causes that ILI9341_Draw_Char() works not properly.
When Size > 1 drawn character seems not clean.

STM32-ILI9341/Src/ILI9341/ILI9341_STM32_Driver.c

Line 354 in 2ed24b6

Buffer_Size = Size;

Changing the buffer_size in ILI9341_Draw_Colour_Burst() to Size * 2 was the solution!

I was getting weird effects when trying to use vertical lines, they changed color mid way.

This is most definitely a bug causing stack corruption when the requested Size < BURST_MAX_SIZE and odd (look at the for loop immediately after). The fix above worked for me as well.

Indeed !
I have experienced some bad divison by 0 with this ILI9341_Draw_Colour_Burst()
if you call it with size=0 then Buffer_Size is 0
At this line :
uint32_t Sending_in_Block = Sending_Size/Buffer_Size; //DIVISION by 0 possible
Major failure !
