Can I damage ALL uart ports by messing with only one?
I disconected a serial device (camera) from tx, rx (27,28) pins of my powered mbed and after that the serial port stopped working. I thought that the pins were burned but they work well as a digital out, I connected my device to the others serial port pins, but none of them is working anymore. The serial port which uses the usb lines is working well. My camera is working also. Any help? thanks
