I tried to match the ili9163c display with Arduino mega 2560 programmed, I promise with the right port, programmed avr two with flc9 hex nothing ..... do I have to rewrite the bootloader? the Pins chosen are the same as uno but with one everything goes, with mega no ..... the pins are 8-12 .... thanks Solozerouno.

Hello

You could try loading the hex file onto the arduino using xloader. That's known to work. The r3 mega should work fine but there is a problem with older mega boards.

The SPI pins on the Mega2560 are:
MISO =50, MOSI = 51, SCK = 52 & SS = 53.
Try those and see if it makes any difference?

I used the Mega 2560 re to drive 4 ili 9163c displays without problems: I used 4 spi in software emulation and that's it, among other things, if I'm not mistaken, the compiled with a few words for each display is only 10-12K See also you to try the software version with pins ranging from 40 to 56 and there are no problems, do not use pins 2-13 in software emulation because it does not work.
Good job.
