Tutorial - Raspberry Pi Stand-Alone Programmer
about 2 years ago
It's very handy to be able to test the serial upload functionality and program the device in one go!
Yes, could it go in the serialupload.sh file to make it easier to change? Not really.
The link to Kevin Cuzner confused me a little as all you need to do is run the sudo apt-get for avrdude and then move the .conf file to the pi directory. Other than this and the serial upload stuff it was plain sailing!
The delay seems to work, just ran through the entire sequence 10 times with no issue. Thankyou!
Yes, it is very strange because Arduino 1.8.5 is able to upload every time without fail. I am now using the same command as Arduino to initiate a serial upload:
sudo /opt/arduino-1.8.5/hardware/tools/avr/bin/avrdude -C/opt/arduino-1.8.5/hardware/tools/avr/etc/avrdude.conf -v -p$DEVICE -cavr109 -P/dev/ttyACM0 -b$BAUD -D -Uflash:w:$firmware:i 2>/home/pi/SERIAL_UPLOAD/serial_upload_results.txt
When it fails it gives the following output:
avrdude: ser_open(): can't open device "/dev/ttyACM0": No such file or directory
Thanks for all your help!
Managed to get everything setup and working. I am trying to use the serial upload functionality on a 32u4 board but having huge reliability problems, works about 20% of the time. Just wondering if you have tried this particular functionality?
Thanks for the quick reply! I didn't imagine it would be such a large file, I will set it up myself.
Looking at making one of these, in the Pi_Grammer setup instructions it references a generic Pi_Grammer image but I can't find this on the GitHub, is it available somewhere else?

I seem to be having some problems with this, firstly when on standby I experience a buzzing noise throigh the speakers, then when playing music a slight echoing can be heard and finnally when I put the volume up to a certain level the peak led flashes and speakers move in and out slowly, but a long way. I'm using a pair of speakers from an old bose docking station and have no information about them. Any suggestions?

I may be trying to hide it; but really I'm fascinated by these pretty lights like any other electronic boff. Why does no one else think this is the coolest thing ever!?!
