GPIO UART1 - ttyS1 Communication
#11

But when i read the input it is toggling '1' and '0'.

May I know if there is any things else that I should do?

Not exactly, I'd correct the statement that the PWM channel has the priority over its UART, which sharing the same pins. No problems if you'll leave the other UARTs on their settings.

If you trying the debugging during boot time, better you leave the things as they are. You just need to plug the adapter on the UART 3 and, eventually, modify extlinux.conf to remove the Plymouth and quiet from the append line.

If you are trying to use this shield (Sixfab Raspberry Pi 3G-4G/LTE Base Shield V2).
I've made it work via ttyS1 and ttyUSB3.


Please explain how your config is arranged.

Any tutorial?`

Regards,
David
