Requirements:
Hardware
- Raspberry Pi with Raspbian (Kernelversion 4.x)
- BME280 Module
- 4 Pin Fan (12v-VCC, GND, RPM, PWM)
Software
- Access to the kernel (load and unload kernel modules)
Setup:
Install required software
To get access to the kernel you have to do the folowing:
sudo apt-get update
sudo apt-get upgrade
sudo apt-get install git bc bison flex libssl-devsudo apt-get install libncurses5-dev
sudo wget https://raw.githubusercontent.com/notro/rpi-source/master/rpi-source -O /usr/local/bin/rpi-source && sudo chmod +x /usr/local/bin/rpi-source && /usr/local/bin/rpi-source -q –tag-update
sudo rpi-source
Now you can view your kernel version (uname -r) and load/unload kernel modules.
load kernel module:
sudo insmod {kernel module}*.ko
unload kernel module:
sudo rmmod {kernel module}*.ko
show all loaded kernel modules:
lsmod
show detailed information about a module:
modeinfo {kernel module}
show kernel log:
dmesg
