After the system is up , i want to use test program for uart? Do you have it?
hello hy_401,
may I know what’s the actual use-case,
I had tested with [url]https://serialport.en.softonic.com/[/url] to check UART connections,
thanks
Dear sir:
I just test the UART comunication. How to use the https://serialport.en.softonic.com/ after the ubuntu system is running on nano etc?
hello hy_401,
that serial port utility is the tool for WindowsOS.
you should setup the UART connections between your Nano and Windows platform. there’re UIs for sending/receiving data.
by the way, the default baudrate setting is 115200/8n1.
Dear sir:
Yes, i know. What is the UIs on nano?
Tks!
hello hy_401,
assume you’re sending data from WindowsOS to UbuntuOS.
you could setup a terminal and running the serial port utility, such as minicom or picocom.
the serial port is ttyTHSx, whereas x start from 0, you may looking for $ demsg | grep THS from kernel init messages to check the UART mappings.
note, the default baudrate configuration is 115200/8n1.
