Hello Legoman,
The ADC component functions: SampleADC, ReadAsInt and ReadAsByte can be included in the macro called by the timer interrupt. The returned value and any control flags can then be saved to global variables.
It is advisable not to do too much more from within the interrupt service routine, but return as quickly as possible to the main program.
