UART1 on AB01: how to get access?

#1

Hello,
It may be a simple question, but I cannot find the answer…
Apparently, there is an available physical UART interface (on pins number 14 and 15. By the way, I found nowhere how to use such numbers…)

How to access it?

Serial1.begin(9600,SERIAL_8N1, UART_RX, UART_TX);

does not seem to work: it stalls.

#2

Please use Serial.begin();

#3

Serial.begin();
launches the UART connected to the USB port, for debugging.
I wanted to use another UART. And the pinout shows 2 pins “dedicated to” another UART port.
Serial1 compiles, but when reading the data, it gets stuck.

#4

AB01 has only one serial port.

#5

And this serial port has been connected to the serial chip.

Hi Mr. Shaffer! it is possible to use serial pins 14 and 15 to communicate with another microcontroller without connecting the USB cable?

Best regards.

#7

Yes, it is possible to communicate with another microcontroller without connecting the USB cable.

#8

thanks for your fast response! I´m using a Helium-CubeCell example sketch should I use the Serial commands as is, or it is necessary to use another library like softserial?

#9

If you connect pins 14 and 15, you can use serial commands as is.

You could also use software Serial to get an additional USART and keep the other for debugging
