to install:

cd
mkdir -p build
cd ~/build
git clone https://github.com/mzandrew/XRM.git

to run:

cd ~/build/XRM/predator
./get_temperatures.py # reads temps from SPI thermocouple
27.9 26.3
./read_serial.py # reads temp + ADC values from microcontroller for ammeter function
24.8 1.368 1.406
./take_pic.sh 
./lights_on.sh 
./lights_off.sh 
./temperatures.sh # grabs snapshot of KEKB status and plots temperatures on it
./make_video.sh # makes video from individual images
./upload_to_samd21.sh # programs microcontroller (ADC for amplifier's ammeter)
./daemon.sh # started in /etc/rc.local upon bootup - runs in a loop once a minute: get_temperatures.py, read_serial.py and take_pic.sh

notes:

logfile for temperatures and voltages (for ammeter) is in logs/temperatures.log
