- I just received and assembled my Monochron kit. It works fine
- I installed the necessary AVR development tools on my Mac as explained here: http://www.ladyada.net/learn/avr/setup-mac.html
- I installed the FTDI Basic module from Sparkfun that came with the kit. A loopback test confirmed that it works.
- I'm using this command line to upload a new hex file to the clock:
Code: Select all
avrdude -p m328p -P /dev/tty.usbserial-A700e5VU -c stk500 -b 19200 -U flash:w:monochron.hex
Code: Select all
avrdude: stk500_2_ReceiveMessage(): timeout
The clock seems to be sending something a 1 second intervals while it is running.
