| what device? | 01/01/70 00:00 | |
| Just the 'integral part' Part of code | 01/01/70 00:00 | |
| you still did not tell the derivative | 01/01/70 00:00 | |

| Here's the wrLCDcom SR | 01/01/70 00:00 | |
| is DELAY_5_1MS timer based? | 01/01/70 00:00 | |
| Yes DELAY_5_1MS is timer based | 01/01/70 00:00 | |
| so, you call one device generating an interrupt fr | 01/01/70 00:00 | |
| Already tried that | 01/01/70 00:00 | |
| then keep it that way | 01/01/70 00:00 | |
| Here's the entire code.... | 01/01/70 00:00 | |
I quick look, not an analysis | 01/01/70 00:00 | |
| Have a look at this | 01/01/70 00:00 | |
| Deriviative??? | 01/01/70 00:00 | |
| Derivative | 01/01/70 00:00 | |
| Oops... Derivative..gotcha | 01/01/70 00:00 | |
