My Ibus project is coming on nicely ( Start of my input on the topic ) so now I have to think about the physical installation.
So far, I have destroyed four Nanos trying to upload to them when the Tx/Rx was connected esewhere. To counter that, I am using a relay in my test rig to disconnect the lines for upload.
Is there any more compact or preferred method for doing this?
The location for the interface will take at least half an hour of undressing the old girl to be able to replace one that has gone bang, so would like to have something pretty foolproof.
Maybe sensing the Nano's USB socket becoming live to switch out the lines perhaps?
