Step 3Programming the SIS-7C
Programming the chip is super easy and is outlined on the second page of the SIS-7C's datasheet here.
You will definitely need a multimeter or other way of figuring out when the "Program Status" (pin 3) pin goes "high." I had the luxury of using a digital lab with LED logic indicators (shhhh, don't tell the CS department) but the layman will just have to use a DC voltmeter.
1. Setup the IR reciever and SIS-7C on a proto-board.
2. Setup a voltmeter to watch pin 3.
3. Momentarily ground pin 12 (the "Learn" pin) and you should see about 5VDC come up on pin 3 very soon.
4. If this happens, you're golden and you should continue to follow the instructions on the datasheet. If pin 3 does not go high, it's debugging time.
