| How to program a stepper driver | 01/01/70 00:00 | |
| Delay | 01/01/70 00:00 | |
| this makes absolutely no sense | 01/01/70 00:00 | |
| tried commenting delay | 01/01/70 00:00 | |
| no offense, but THINK | 01/01/70 00:00 | |
| ah | 01/01/70 00:00 | |
| yes | 01/01/70 00:00 | |
| What is oscillator speed? | 01/01/70 00:00 | |
| osc speed | 01/01/70 00:00 | |
| MEGAHENRY? | 01/01/70 00:00 | |
| oops | 01/01/70 00:00 | |
| Try this | 01/01/70 00:00 | |
| Not the cure | 01/01/70 00:00 | |
| SWITCHES | 01/01/70 00:00 | |
| Was that YOUR simulator, Jon? :-) | 01/01/70 00:00 | |
| Pinnacle52 | 01/01/70 00:00 | |
| Found it | 01/01/70 00:00 | |
| Almost there | 01/01/70 00:00 | |
| any LEDs? | 01/01/70 00:00 | |
| no led's | 01/01/70 00:00 | |
| then use the scope as a LED... :-) | 01/01/70 00:00 | |
| but not THIS nonsense! | 01/01/70 00:00 | |
| good idea | 01/01/70 00:00 | |
| Try it now. | 01/01/70 00:00 | |
| I think, Steve meant, he will try to use the scope | 01/01/70 00:00 | |
| Oh..OK | 01/01/70 00:00 | |
It works | 01/01/70 00:00 |
