I built this example(https://microchipdevelope...ld-comparison-example) on PIC18F57Q43 Curiosity Nano board, what I have altered are:
 
1. RA0 for POT.
2. UART for EUSART
3. RF0/RF1 for TX/RX.
 
but, I no data output either in CoolTerm or Data Visualizer.

So what is your question?
You have not shown your altered code, so there's no way we can comment on what you did.
 

@ric,

The Original Poster's(OP) problem is using a tutorial for the PIC16F18555 and wants to use the PIC18F57Q43.

@mian.qi,

I have worked through the tutorial and targeted the PIC18F57Q43. It seems to work in the MPLABX simulator, but I do not have a PIC18F57Q43 Curiosity Nano board to test it with.

Give this code a try in your hardware, it may even work.

The zip file is too big for attachment, so I couldn't attach it, my question is there was no output either in CoolTerm or Data Visualizer.
 
When I tested the code, there was a device not recognized error.

The image you attached is too low resolution, it is unreadable.
 
If the text in the MPLABX output window is ASCII then copy and paste that text in your post.
 
DO NOT POST A SCREEN SHOT OF MPLABX COMPILER DIAGNOSTICS!

Looking back, the target device is "MCV20USB"
Shouldn't that be "PIC18F57Q43" ?
 

It is Sunday tomorrow, I wish you two have rest, so you needn't answer my question before Monday.
My question is: I tried the fourth example - ADCC Spike Detection in this Application Note "TB3263 - Getting Started With ADCC for PIC18", my files are attached as txt file. I thought I have fixed all the holes in it, and the files could be built and programed into PIC18F57Q43 Curiosity Nano board. But I the output in CoolTerm and Data Visualizer COM5(the serial and CDC port in my computer) were all empty.

Your problem is that you are still using examples for a controller that is different from the hardware you have.
 
Perhaps you will need more experience before you can find and fix the small differences between the PIC18F47Q10 and the PIC18F57Q43.
 
Based on the low resolution screen shot you attached to post#4 you seem to be using MPLABX v5.30.
 
The PIC18F57Q43 may not be fully supported by MPLABX v5.30 so you may need to use a newer release.
