Re: Monochron Updating Issue

Hi there,
When using avrdude, the -P argument must be followed by the port name of the device that connects to your Monochron..
Since in your example the next argument is -b, avrdude assumes that -b is the port name, which apparently fails to work :-).
Example for Linux:
avrdude -c arduino -p m328p -P /dev/ttyUSB0 -b 57600
Example for Windows:
avrdude -c arduino -p m328p -P COM3 -b 57600
Depending on the interface device connected to your Monochron, OS and avr toolchain, the values for -P and -b may differ.
The commands above work nicely for me using FTDI-Friend v1.1 in combination with Debian Linux 8 and 9 (it's been quite some time since I did avr stuff on Windows), using the Emuchron firmware.
Cheers, good luck & enjoy your clocks!
