I am trying to do PAL composite video output with Arduino Nano. I am using Atmel Studio 6, not the Arduino IDE. I am sending out the picture data via SPI. On the TV I could not see the text I tried to produce, so I tried to run my program in the Atmel Studio simulator (to use it as a logic analyzer). But in the resulting stimuli file I also do not see the MOSI pin changing.
I am using the A0 pin (PORTC bit 0) to send out the sync signal, that appears correctly in the output .stim file: PORTC changes exactly at the right time. But PORTB does not change at all.
My program can definitely be buggy, but that is another topic... the question is, can Atmel Studio Simulator simulate the SPI at all?
