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.
