- test spidev
- optimize spidev bytes - doesn't work with less than 3 bytes input
- IO PI Plus
- solder connectors
- try LDRs with pulldown
- try interrupts
- install spidev (from http://raspberrypi-aa.github.io/session3/spi.html)
git clone git://github.com/doceme/py-spidev
cd py-spidev
sudo python setup.py install
- Install timidity https://packages.debian.org/jessie/sound/timidity
https://www.howtoinstall.co/en/debian/jessie/main/timidity/
sudo apt-get install timidity
- Start timidity in server mode and test: http://raspberrypi.stackexchange.com/questions/7359/python-synth-with-raspberry
timidity -iA -B2,8 -Os -EFreverb=0(somewhere in screen ?)
- Test timidity
aplaymidi -l
aplaymidi -p 65:0 somemidifile.mid
Where 65:0 has to be replaced by the MIDI sequencer that you see after running aplaymidi -l
