I want three(3) different networks, running to three(3) different locations and be able to detect not only the device, but also the network it is connected to. Yep, got that bit. Leon Botha said:
Hence I need to dynamically allocate "button_io" to P2.0 or P2.2 or P2.4 No, you don't! As Russel & I have both explained, it's no big deal to replicate the bit-level functions so that you have one set for each 1-Wire net; eg: unsigned char Ow_Reset_1(void); // Perform a Reset on 1-Wire net No 1 unsigned char Ow_Reset_2(void); // Perform a Reset on 1-Wire net No 2 unsigned char Ow_Reset_3(void); // Perform a Reset on 1-Wire net No 3http://www.8052.com/forum/read.phtml?id=85182 http://www.8052.com/forum/read.phtml?id=85171 I have also suggested an alternative of driving all three simultaneously: http://www.8052.com/forum/read.phtml?id=85114 http://www.8052.com/forum/read.phtml?id=85171 Have you looked at that? Could it work for you? |

| I do not understand | 01/01/70 00:00 | |
| You mean Dallas 1-Wire? | 01/01/70 00:00 | |
| Re | 01/01/70 00:00 | |
| What's the problem? | 01/01/70 00:00 | |
| I think that... | 01/01/70 00:00 | |
| indirect bit addressing | 01/01/70 00:00 | |
| The same iButton on all 3? | 01/01/70 00:00 | |
| sbit | 01/01/70 00:00 | |
| access all 3 , one at a time | 01/01/70 00:00 | |
| I had the same problem | 01/01/70 00:00 | |
| Lets try again | 01/01/70 00:00 | |
| Need ? | 01/01/70 00:00 | |
| Why? | 01/01/70 00:00 | |
| There is always the switch statement | 01/01/70 00:00 | |
| something like this... | 01/01/70 00:00 | |
| Simultaneous example | 01/01/70 00:00 | |
| Use MASK rather than bit address | 01/01/70 00:00 | |
| Oooops, sorry... | 01/01/70 00:00 | |
| Multiple 1Wire | 01/01/70 00:00 | |
| How to post code, and possible hang-up | 01/01/70 00:00 | |
| simultaneous? | 01/01/70 00:00 | |
| would even be better | 01/01/70 00:00 | |
If it worked! | 01/01/70 00:00 |
