I would first assume that since it knows how to blink, it also probably limits it's own current. I would further assume that 20mA would be enough to drive it. A lot of assuming, but if true, then you could probably replace one of the GPO output resistors with a piece of wire and hook up the blinking...

Like Stig says, that's the only way. The key scan works by making the previously grounded pins high one at a time to find out which one is making the previously high pin to be now low. So, you *must* short two pins together. An analog switch attached to the TTL input which connects a column and a ro...

The techs don't know an Atom from Adam, and neither do I. However, I am fairly sure that 0x5c is 01011100 and not 01010000. Seriously, please read the specification provided by the only people qualified to write one - Philips. I am sure that Henry can provide a link if you find that google.com canno...

Yes, that other thread is excellent information that I had forgotten about! I actually thought it was GPO4 or 5 that was on at powerup... Whichever one it is, it is always the same, but the rest will be off at powerup. As for these resistors, it sounds like Henry did not quite understand the questio...

You are correct - that is not what you should be seeing. Please endeavor to try the same sort of thing with RS-232 first to make sure that the values that the unit is TRYING to send back are as expected. If so, then you can try to discover why you are not getting that. The RS-232 and I2C use exactly...

I thought you were asking about which processor you could use? This is why I sent you to HVW. If you said you were looking for someone to build you a truch and do all the programming, I would have not sent you there. So, lets see if I have this straight. You have a truck with independent digitally c...
