Has anyone any practical experience of building a dual slope AtoD using a Philips P89LPC932 micro? I have read the Philips app note about this so it certainly seems possible. I don't need much resolution and a few samples per second would suffice - I am only reading the pots in a joystick on a wheelchair. The app note gives example code for a sigma delta method but that is unnecessarily complex for this application. Anyone have any dual slope application code for this micro they can share.
