No guarantee! No Warranty! No return! Use the codes at your own risk.
Find here demos, code snippets, collected, implemented, assembled, fixed, modified, adjusted, extended examples from literature, reimplemented by the idea, or simply kernel sources. I tried to provide documentation and references to the best of my knowledge, check out the provided READMEs. Some demos require additional hardware.
All demos were verified on my RPi 3b 64-bit, with a linux 6.3.x. In some cases x86 (64-bit) with same kernel. For the usb demos I used a PIC32 board as communication counterpart.
The sources are built with make. In case provide KERNELDIR, ARCH, CROSS_COMPILE in the environment. KERNELDIR defaults to /usr/src/linux.
