I’m trying to get anything to print to the serial monitor. The code version works fine.
Internal XOD uploads work fine. Buttons, LED’s etc… Can’t get anything in or out of Serial.
Can anyone give me a hint? I’ve been banging on this for a while now.
Now I’m just trying all the nodes. See if I can get anything Serial/UART.
Thanks for any help…
Here is the upload confirmation if that helps.

avrdude done. Thank you.
=== Done ===
To use the serial monitor or connect to another application, you must stop debugging on XOD, or load without debugging.
ps: in xod you will see it that way
Thanks for your help! Thought I tried that. Guess not.
Can you give me an idea of “write-byte” vs “print”?
I’m trying to stream out a float value. “print” looks to be for string data. Should I use that then convert the data type on the other end?
Does “write-byte” work best when transferring numerical values?
I think I have read that it is better, but as I commented in another post my knowledge about uart is very limited.
My way of learning is to take knowledge of what I need, until now do not do any project with uart.
Surely there is someone with more knowledge to help you, but you must be patient
