PS2Mouse (AMX) not working correctly
« on: 19:04, 13 April 19 »
Hello everyone!
I build the PSMouse interface (http://www.cpcwiki.eu/index.php/PS2Mouse) and it was running almost on the first try. Problem is that the mouse movement is working fine (I tested it in Art Studio and AMX Art), but the buttons are not working all the time (it's like working-not working-working... with random period).
The difference between original scheme and my creation is that I used crystal + 2 capacitors and not the oscillator.
Do you have ideas where should I look for a problem? Thanks!

mikezt,
Are there dry joints?
Could put up a picture of the board.

  • It's not broken, it just hasn't been fixed yet.

Does the LED blink once when you press a button? Or does the LED start flashing a few times when you aren't touching the mouse? If the second one is happening, the circuit might be unstable and is resetting. A picture of your device might help the diagnosis.

Hi!
Sorry for a delay with reply.

I tried to resolder the board and I checked all connections, but it's still working the same way. The LED blinks once when I press a button and it's on when I'm moving the mouse. In idle is the LED always off. Here are pictures of my board.

Hmmm, some of those joints don't look good at all. It looks like your iron was possibly too hot or the solder might be quite old too. I'd at least re-solder the joints I've circled below, because they all could be possible causes. You should never be able to see into the hole when the joint has been soldered.

Did you etch the board yourself? It looks very nicely made.
