| Jul 11, 2014 at 9:50 | comment | added | Majenko | Yes, that is what I mean by the "square wave" - it's the pattern observed on the scope by connecting it to either the TX or the RX pin while sending (or receiving) a U. | |
| Jul 11, 2014 at 9:49 | comment | added | Rookie91 | I meant about dirctly connecting the rx and tx pin of the controller to the scope probe and watching the controller sending 'U' in a tight loop.Is it the correct way.Sorry for my bad english | |
| Jul 11, 2014 at 9:45 | comment | added | Majenko | That's 'U', not 'u' (upper case is important). I'm not sure what you mean by "check the oscilloscope at the rxt and tx pin of controller and verify it". | |
| Jul 11, 2014 at 9:43 | comment | added | Rookie91 | Can't we check the oscilloscope at the rxt and tx pin of controller and verify it?I trust it would give the baudrate.And 'u' seems to be the master short cut. | |
