#170936 - I should have known Responding to: ???'s previous message |
stupid me I should have known! Thanks sir, greatly appreciated!
Hence as I see it, all I need to do is to connect TXD (P3.1) directly with Din on the Xbee Explorer Regulated breakout board, with no logic shifting (there's the diode connected to Din dropping the voltage to a safer level on the same Xbee regulated board, right?). Also I should connect the Xbees Dout with an HCT family buffer to convert logic levels from 3v3 to 5V first and then connect the buffer's output to the 8051 RxD(P3.0) for the 8051 UART to 'interpret' the logic levels correctly. Correct me if I'm wrong. Kai |

| Why? | 01/01/70 00:00 | |
| what are the levels? | 01/01/70 00:00 | |
| 3V from the Xbee but... | 01/01/70 00:00 | |

| Woops. I was half asleep. | 01/01/70 00:00 | |

| I should have known | 01/01/70 00:00 | |
| Important that you use HCT and not HC | 01/01/70 00:00 | |
I know ; - ) but thanks! | 01/01/70 00:00 |
