In a very semplified way you suggest that I have to: use libruio to start the measurement and read the system clock using one PRU use the other PRU to increase ADC sample freq ? I'll probably need to read more about scratchpad register and XIN XOUT and all the functionality in libruio.
but first I should loose my specs in order to make things easier, lets say that ms accuracy is acceptable, should it be possible to avoid using PRUS?
