Whats going on here??

[radiogareth]

This is some snooker scoreboard code that simulates fine.

However, in hardware the b0 register will not count up past 1, UNLESS the buttion is held down.
The similar colour count section works fine using b1. What are we missing?? - both teacher and pupil are involved here!!

Thanks

Gareth

Simulation but not hardware?

Schematic please.

In the simulator b0 only counts up when the input B.0 is high. That is what you programmed it to do.

The buttons in the simulator are toggle buttons so if you press it once it stays on then turns off on the second press. The buttons in real life are push to make switches so they only stay on when held down and therefore the input pin is only high when the button is held down.

OK, sorry no suitable schematic at this point....
We realize that the simulator button toggles, a quick double click and the simulation works as expected.

The hardware works as expected too, but B0 will not increment past 1 UNLESS you literally hold the button down as the code runs round. Switches are de-bounced in hardware too.
B1 does increment as expected, per button press. The hardware is the same on both, you can swap the button outputs around and the fault follows ie B0 does not increment past 1. It must be something simple, but I/we can't see it.

BTW, thanks for putting the code tags on the listing, could we have them in with the Smilies perhaps??

Do you really have a colon here?


goto seered:

You can remove that line entirely.
