I'm trying to underestand whether I can use the video out of P21 for a
general analog-out signal. For example, can I program it go give 1 bit
(ON/OFF) signal? 2-bit? n-bit?
Does anybody know of a good description of the NTSC signal? Availbale
through the web?
The whole point is to use the external clock as a reference of a signal
that comes out. Otherwise i would have to connect an external timer, and
read it in polling mode, which would result in temporal jitter in the
analog signal that I output.
If I could use the video out as a 1-bit high frequency ADC, I could do
audio out with the correct oversampling and filtering.
