| RS232/serial port of PC for 3 volt microcontrollers | 01/01/70 00:00 | |
| No | 01/01/70 00:00 | |
| Try searching for: MAX3232 or SP3232 | 01/01/70 00:00 | |
| Transistor level shifter | 01/01/70 00:00 | |
| Availability | 01/01/70 00:00 | |
| only if you have +-12V | 01/01/70 00:00 | |
| For transistor based RS232 | 01/01/70 00:00 | |
| Bad idea! | 01/01/70 00:00 | |
| why do these 'maybe' circuits keep popping up? | 01/01/70 00:00 | |
| Few designs have suitable +/- supplies | 01/01/70 00:00 | |
| More to it than just voltages | 01/01/70 00:00 | |
| Yes of course | 01/01/70 00:00 | |
| because they do mostly "work" most of the time | 01/01/70 00:00 | |
| 'mostly' is never stated | 01/01/70 00:00 | |
| I suspect that it's actually quite high... | 01/01/70 00:00 | |
| If he had the supplies ... | 01/01/70 00:00 | |
| Get from other parts of India | 01/01/70 00:00 | |
| Why would you want to use one of those? | 01/01/70 00:00 | |
| Whats Your preference 3V RS or AT89c2051? | 01/01/70 00:00 | |
| If it's specifically for a PC, is RS232 a good choice? | 01/01/70 00:00 | |
