Unable to access the bootloader

Post by British_Tech_Guru »

I have an Arduino Metro and no matter how much I push the little microswitch, plug and unplug and combinations thereof, it just does not drop into bootloader mode, becoming visible to my laptop as a USB drive. It seems to have C++ ready loaded. That's fine but I want to use it with Python for the moment. Any suggestions or do I just suck it up and try to refresh my 30 years gone C++ coding skills?

And just for light relief - a video I made of my Metro...

Bulletproof indeed. Thanks for the video.

This model of Metro is 328p based so it does not support Python. You will need to use the Arduino IDE. You will not see a boot drive on your laptop with this model.

Make sure you install the necessary serial drivers.
Mac & Windows People! Don't forget to grab & install the CP2014 VCP drivers from SiLabs to make the COM/Serial port show up right! The default drivers may not support this USB/Serial chip

Thanks, that clears things up. I'd seen a Python file for it but if it's C++ only - oh well. I'll have to dig out my C++ books and try to remember the C++ I studied in college in 1990.
