A Raspberry Pi Hardware Abstraction Layer for C/C++ projects.
Not completed. Grows as I need it.
The system tests can also be considered as examples 😉
CAUTION! Currently only supports models with the BCM2836, BCM2837 and BCM2837B0. If this software is executed on another hardware it may lead to permanent damage! See the v0.2 branch for hardware awareness. A Pre-Release is available! 😊
Unexpected behaviour may be observed on alternate functions (see https://elinux.org/BCM2835_datasheet_errata#p92_to_95_.26_102_to_103).
Search for DEVSPEC comments in code to find the critical portions.

These all have the 40 pin header, which has the same pinout on all models listed above.
The emulator can be used to run your project on your working machine. To build the emulator project
include all the same files as in the main project, plus the emu.cpp file (don't include any other
rpihal source file to the build, nor link to the rpihal), and define RPIHAL_EMU on the compiler level (not anyehere in
source nor header files). See the staircase example as a reference.
To create a new emu project in Visual Studio use the New > Project From Existing Code... funtion and create an empty
console application. Then add all the needed source files and add the include directories.
The left and right mouse button can be used to click (push a button) or toggle an input pin.
The emulator uses the OneLoneCoder Pixel Game Engine for the graphics.
