#126643 - UART start bit detection? |
I have an application where it might be advantageous to detect the start bit of a UART transmission in certain cases.
Can I just poll the appropriate port pin P3.0/Rx, even while the UART is enabled ? The MCU does not need to do anything else while in this state, so busy waiting is not a problem. Or do I need to turn off the UART first before polling the pin ? Or would it be a better solution to connect P3.0/Rx to another free GPIO pin and poll it instead ? |
