#164638 - the point of asking nonsense questions... Responding to: ???'s previous message |
... is to get you off the "standard" track of thinking.
While it's true it would "flicker" rather than "stay low", I hope my nonsense question made you to pull out a multimeter and measure the actual voltage directly on the LPC's Rx pin, and also that it made you to re-read the section on UART pins initialisation in the manual. I know nothing on the LPC's, so I am as good as Andy's proverbial teddy bear in this case. Jan |

| Yes they are set - Why? | 01/01/70 00:00 | |

Thanks - Done | 01/01/70 00:00 | |
| aren't the LPC9xx's pins... | 01/01/70 00:00 | |
| Yes but - it also happens in the real hardware | 01/01/70 00:00 | |
