Raspberry Pi Software to connect to an incubator device through RS232 and to an external sensor PCB via CAN. All data measured by the sensors in the incubator and the external PCB are collected and transmitted to an influxDB database.
See the press release of this projet at: Pforzheim University
To build the software for your PC just use the CMake-File and your favorite build environment:
mkdir build
cd build
cmake .. -DCMAKE_C_COMPILER=clang -DCMAKE_CXX_COMPILER=clang++ -G "Ninja"
ninja
If you want to compile the project directly on the Raspi just skip this step and use the method from above!
To use cross compilation install all needed dependencies on the Raspberry Pi:
- Base-devel / build-essentials
- fmt
- clang
- ninja
Copy the whole root folder of the raspberry pi onto ~/sysroot.
Change the sysroot path in the cmake call to your local sysroot path (needs to be absolute!) and then run:
mkdir build_pi
cd build_pi
cmake .. -DCMAKE_C_COMPILER=clang -DCMAKE_CXX_COMPILER=clang++ -DCMAKE_TOOLCHAIN_FILE=../toolchain-rpi.cmake -DCMAKE_SYSROOT=/home/<USERNAME>/sysroot -G "Ninja"
On the Raspberry Pi Zero 2 W is running aarch64 Linux with the raspi kernel. Just install aarch64 as described in the Archlinuxarm-Wiki. Note: Use the 64-Bit kernel! https://archlinuxarm.org/platforms/armv8/broadcom/raspberry-pi-zero-2
After that you can boot your pi and update the kernel to the raspi kernel with pacman.
pacman -Syyu
Update the following files /boot/config.txt to
# See /boot/overlays/README for all available options
dtoverlay=vc4-kms-v3d
dtoverlay=disable_bt
initramfs initramfs-linux.img followkernel
[pi4]
# Run as fast as firmware / board allows
arm_boost=1
[all]
enable_uart=1
dtparam=spi=on
dtoverlay=mcp251xfd,spi0-0,oscillator=40000000,interrupt=25
and the file /boot/cmdline.txt to
root=/dev/mmcblk0p2 rw rootwait console=tty1 selinux=0 plymouth.enable=0 smsc95xx.turbo_mode=N dwc_otg.lpm_enable=0
Reboot!
