This guide is only for x-c1 adapter shield.
==How to setup script??For Raspbian OS==1. Once you have logged into your Raspberry Pi from the command line, run the following commands
sudo apt-get update
sudo apt-get install python-smbus
sudo apt-get install pigpio python-pigpio python3-pigpio
git clone https://github.com/geekworm-com/x-c1.git
cd x-c1
sudo chmod +x *.sh
sudo bash x-c1.sh
sudo reboot
xoff
#xoff is safe shutdown command, you can press button 3 seconds to safe shutdown, or long press 7-8 seconds to force shutdown.
At this time, if the fan is still not rotating, we need to continue to install the pwm fan control script We can manually please run the following commandscommand:
sudo python /home/pi/x-c1/x-c1_pwm_fan_control.py&
But we hope that the script can be executed automatically when the Raspberry Pi board boots, we can use crontab system command to achieve it. please refer to the following
sudo crontab -e
Save and exit (CTRK + O and ENTER to save it). In nano editor, you do that by hitting CTRL + X, answering Y and hitting Enter when prompted.
