#110605 - Analog comparator on AT89C2051 Responding to: ???'s previous message |

Hello. Can anyone please guide me on how to use the analog comparator on the AT89C2051. There's nothing mentioned in the datasheet.
Jack. Welcome to the group Jack. To use the analog comparator on the Atmel 89C2051/89C4051 just set P1.0, P1.1 and P3.6 HIGH (set to 1's). SETB P1.0 SETB P1.1 SETB P3.6 Apply two different analog input voltages (of a value between 0 and 5V)to P1.0 and P1.1. You can then read bit P3.6 to see if the input voltage on P1.0 is greater or less than the voltage on P1.1. JB P3.6, OutputHigh Cheers, Bert |

| Ok | 01/01/70 00:00 | |
| Active - hummmm.. | 01/01/70 00:00 | |
| Advise needed! | 01/01/70 00:00 | |
| Have you seen the appnotes? | 01/01/70 00:00 | |
| Yes I have | 01/01/70 00:00 | |
| yes | 01/01/70 00:00 | |
| P3.6??? | 01/01/70 00:00 | |
| Finally working, maybe? | 01/01/70 00:00 | |
| Surely working! | 01/01/70 00:00 | |

| Not technically correct! | 01/01/70 00:00 | |
| so, it is "testing" which is worthless | 01/01/70 00:00 | |
| True but... | 01/01/70 00:00 | |
| No, I do not do as above. | 01/01/70 00:00 | |
| Sure | 01/01/70 00:00 | |
