#171142 - It's a P89v51RD2 Responding to: ???'s previous message |
My chip is an NXP 89V51RD2.
I'm not sure whether it works in the push-pull mode. Because last month, I wrote a code for an IR sensor module with an LM324, and it was working fine. Similarly, an ADC0804 is working just fine with this board. Also, when I make this port 0000 0000,and when I check the port at the end of conversion,the pot pins remain 0000 0000. |

| Don't feed other pins without VCC | 01/01/70 00:00 | |
| CS and RD working. | 01/01/70 00:00 | |
| Wrong understanding of ADC! | 01/01/70 00:00 | |
| But according to Mazidi... | 01/01/70 00:00 | |
| No, you don't! | 01/01/70 00:00 | |
| Sorry! | 01/01/70 00:00 | |
| How do you see that? | 01/01/70 00:00 | |
| The LCD shows a 255. | 01/01/70 00:00 | |
| But this can have zillions of reasons... | 01/01/70 00:00 | |
| Never retype source code when posting | 01/01/70 00:00 | |
| Working! But with errors... | 01/01/70 00:00 | |
| You must convert raw ADC reading into temperature | 01/01/70 00:00 | |
Self-heating? | 01/01/70 00:00 | |
| Configured as push-pull? | 01/01/70 00:00 | |
| It's a P89v51RD2 | 01/01/70 00:00 | |
| Difference only noticeable if contention | 01/01/70 00:00 | |
| then STOP what you are doing | 01/01/70 00:00 |
