..NOW WEN I CONNECT THE MSB TO THE INPUT PORT THE VOLTAGE AT THE PIN TIES ITSELF TO ZERO NO MATTER HOW MUCH PRESSURE I EXERT IT REMAINS ZERO..I DONTKNOW WHTZ THE PROB..I NEED HELP FROM ALL QUARTERS AS SOON AS POSSIBLE.. Heart attack... Don't you think that telling us what pressure sensor and what amplifier you use was a good idea? Kai |

| To what port pin do you connect the MSB? | 01/01/70 00:00 | |
| and a schematic | 01/01/70 00:00 | |
| 1s written to P3.0? | 01/01/70 00:00 | |
| Modify your user profile | 01/01/70 00:00 | |
| yes | 01/01/70 00:00 | |
| What shows the voltmeter,... | 01/01/70 00:00 | |
| multimeter | 01/01/70 00:00 | |
| So you have 0V all the time at P3.0,... | 01/01/70 00:00 | |
| wen i connect p3.0.. | 01/01/70 00:00 | |
| Yes, but what if the ADC isn't connected? | 01/01/70 00:00 | |
| no no .. | 01/01/70 00:00 | |
| Ok, different try... | 01/01/70 00:00 | |
| precisely.. | 01/01/70 00:00 | |
| Does it also work, ... | 01/01/70 00:00 | |
| i didnt try it.. | 01/01/70 00:00 | |
| Just to see, whether there's an internal damage | 01/01/70 00:00 | |
i never thought of that .. | 01/01/70 00:00 | |
| modified | 01/01/70 00:00 | |
| Thanks, please publish your schematic again... | 01/01/70 00:00 | |
| sure | 01/01/70 00:00 | |
| Thanks! | 01/01/70 00:00 |
