I'm sorry for pasting here, since I could not find better suitable place for this topic.

 

I found there were RF0-RF1, UART TX/RX, and CDC all in PIC18F57Q43 Curiosity Nano board, but I couldn't see output either in Data Visualizer or other Serial tool, has here anyone know how to set of config it? IN searching for solution I found a manual(https://ww1.microchip.com/downlo...), but it couldn't give me useful info I want.

The Data Visualiser was an Atmel thing - is it supported/implemented on PIC boards ?

 

If not, there are plenty of other things that can capture data from a serial port & graph it ...

Top Tips:

  1. How to properly post source code - see: https://www.avrfreaks.net/comment... - also how to properly include images/pictures
  2. "Garbage" characters on a serial terminal are (almost?) invariably due to wrong baud rate - see: https://learn.sparkfun.com/tutorials/serial-communication
  3. Wrong baud rate is usually due to not running at the speed you thought; check by blinking a LED to see if you get the speed you expected
  4. Difference between a crystal, and a crystal oscillator: https://www.avrfreaks.net/comment...
  5. When your question is resolved, mark the solution: https://www.avrfreaks.net/comment...

If you can't get output on a serial terminal, then DV does not have a chance... Get the serial data going first, then feed DV data with it...

Thanks to gchapman, your signature led me to know Buckminster Fuller. I have thought of " Dare to be naïve. " as "Be afraid to be naive."laugh

I have seen output in terminal, now I want to see it in graph in Data Visualizer. From this page(image), I guess "USART_Write()" is the key link.Since I used PIC18, so I think maybe it is "UART_Write()".

There are some youtube videos which might be useful: "Visual debugging with MPLAB X" https://www.youtube.com/watch?v=...
