Load Audacity
Start the recording
arecord --device=hw:1,0 --format S16_LE --rate 44100 -c1 test.wav
Will record signed 16-bit (S16_LE) audio at 44100 Hz (--rate 44100) mono (-c1) audio to test.wav. We’ve noted that any audio input will be echoed out the speakers as well
You can have a little VU meter show up if you add to the-V mono command line. Press control-C to quit
aplay --device=plughw:1,0 test.wav

–Installing a GPS Daemon (gpsd)
sudo apt-get install gpsd gpsd-clients
–disable a systemd service that gpsd installs and that messes with manual interaction (our routines)
sudo systemctl stop gpsd.socket
sudo systemctl disable gpsd.socket
–Run gpsd manually
sudo gpsd /dev/ttyUSB0 -F /var/run/gpsd.sock
cgps -s
–Kill it
sudo killall gpsd
–To programmatically access gpsd
pip3 install gps

3.5 Screen
========================================
========================================
====================
==== USING 3.5″, 5″, 7″ or HDMI screens
====================
— MAKE SURE that SPI interface is turned on
— then try
git clone https://github.com/waveshare/LCD-show.git
cd LCD-show/
chmod +x LCD35-show
— if that doesn’t work rename the LCD-show directory and try
sudo rm -rf LCD-show
git clone https://github.com/goodtft/LCD-show.git
chmod -R 755 LCD-show
— switch screen output to 3.5 and rotate sceen 180
cd LCD-show/
./LCD35-show 180
— switch screen output to hdmi
cd ./LCD-show
./LCD-hdmi
