 | | Spybot meets M8 Mikrocotroller
|
|
I’ve started a project to extend the spybot port via an atmel M8 mikrocontroller mini modul.The modul is appropriate together with a battery on the roof of the spy. The modul is connected with the spybot by the vll interface. The software for the M8 (...) (22 years ago, 26-Nov-03, to lugnet.robotics.spybotics)

Having investigated rotations sensors thoroughly, I conclude they have some serious design flaws. Most notably, some samples taken during voltage transitions can be impossible to differentiate from samples at entirely different rotational positions. (...)

Maybe if you put capacitors in series at the inputs of each flop, your test points might have less vertical slope. I'll probably use the simulator to (...)
