STDIO(UART TX RX) can be use to communicate with other peripherals?

Hi, Can we use UART STDIO(TX/P0_18/D1, RX/P0_13/D0) to communicate with other peripherals ? Does it reserve for only STDIO?

I tried sending some bytes over UART(P0_18/D1, P0_13/D0) using putc member function but not receive any data. Could you please anyone clarify this.

Thanks & regards, Sushil

Is there any way to disable STDIO UART and use that to communicate with external peripherals?

Hello Sushil Deka,

yes, it's reserved for STDIO functionality. It is initialized for functionas like _write, _open, _read (input and output).

Hi Martin, How can I connect a UART with arduino PINS? Can I use D8 and D2 for TX and RX?

regards, Sushil
