Is there hardware on the BitsyX and/or other products that allows for a variable frequency pulse? I see that there is some support for variable frequency PWM with the ADSmartIO. However, the frequencies are somewhat limited in resolution.
Could the RTC or some such thing be programmed to produce a pulse.
I'm interested in generating a pulse and then bringing it back into a GPIO pin to generate an interrupt that drives some data collection for the board. It'll be in the 50hz range, though I'm interested in possibly going faster.
After looking through the documentation for the BitsyX, it appears that the ADSmartIO processor (Atmel 8535(L?)) can certainly provide timer pulses. Can I get access to the source for ADSmartIO? Do you use the standard Atmel development tools?
