Topic: Uno - prevent multiple COMM port enumeration? (Read 274 times) previous topic - next topic

Hello,
I have 20 Arduino Uno devices to program with the same program - for 20 identical instances of my project.

Each time you connect a different Uno, it enumerates a new COMM port.

Is there any way to change this behavior? I have 20 Arduino's to program and it is tedious to keep going into the device manager and deleting the COMM port of the Arduino I just programmed...

Thanks,

Use the ICSP to program them. (bootloader will be removed)

Are these stand alone or separate UNOs?
The way you have it in your schematic isn't the same as how you have it wired up!

These are stand-alone Unos with a custom shield.

I don't want to eliminate the bootloader - I want to continue to use the bootloader to update code in the future. It's just that programming 20 in a row results in 20 enumerated COMM ports (unless I delete them...)

Thanks,

If these are DIP packages move the I.C.s from each destination UNO to an UNO plugged into the USB (Cable removed obviously while going so).
