When I upload a sketch to my Uno R4 Wifi (which I just received today), nothing happens except the built-in LED throbs. I push the reset button on the board and everything is fine.
A few times I got the new board to work as expected, but mostly it required a button push to complete the task.
Any ideas?
Can you give us more details? Which version of the IDE are you using? OS?
The latest: IDE 2.1.1, Mac OS Ventura 13.4.1
Are you using the provided the USB cable (assuming one was provided) or another method of upload?
There wasn't one provided. I'm using a USB cable, though.
I don't think it's a cable issue as the sketches upload just fine, it's that they sometimes don't start running without intervention.
By the way, I also bought a Minima and it works perfectly. I was hoping with the extra memory that I could start using stdio.h again. Mixed results: still no floating point support.
Writing 10 or more Serial.print() statements when one sprintf() could have done the job is frustrating, especially since the C format codes are tattooed into my brain.
