I was looking at the datasheet of an ADC at which point it came to my mind if it is possible to use the OMAP's GPIO pins and interrupt lines to read in the ADC values. In this case, supposing that we have 12 GPIO lines on the OMAP wired to the ADC's 12 output lines representing the 12 bits, and then an interrupt generated by the ADC signals the validity of the data, how long would it take for the OMAP's GPIO processor and interrupt features to read in the data, and be ready for the next set of data?
ghasem.
