Oops this morning we installed everything fresh on another Mac, now it all works! Few small things still but we are ironing those out, will post it all on our Interactivation projects site soon.
Thank you Sparkfun people for all your cool circuits, it has made our research and design work so much easier in the last years, fab!
This is following from member #4643 & 37129, we are still struggling to get the circuit working properly. As mentioned above, one of the segments (“E”) doesn’t work on any of the digits. Digging further we traced this back to the pins_arduino.h file, our sketch linked to the wrong one which didn’t describe the extra pins of the ATMega chip PB6&7 (not needing the external crystal) as digital pins D22 & 23. Indeed D22 is controlling the E-segments. However, when we do link to the right .h file, the Analog Inputs A6 & A7 (which worked previously with the wrong pins file…) stopped working, we get error messages from the compiler that “A6” & “A7” don’t exist. We tried “ADC6”, no luck. This may be something simple, any suggestions? Really keen on getting this circuit to work, for a project with interactive hand counters for a rehab ward where this can make a big difference.
Thanks for that tip, will try that!
Sorry it might not be clear from our previous message, but the case is: we want to put Arduino code on the ATMega238 which is on the displays breakboard itself, so without an extra Arduino! So we just connected a header for the FTDI connection to the display and try to put the code on there!
Here is a picture of it
Anyone more experience with this so far?

We have wired up this nice unit with an FTDI Basic 3.3V, installed the hardware profile for the Arduino IDE, but can’t make the display work. We wrote a sketch with Serial.begin(9600) and Serial.write(‘2’) but nothing appears on the display. The Arduino Examples section on the Github is empty, and so is the Customizing the display section…. help!
