A superheroic hardware abstraction layer for doing embedded programming on supported platforms like the Raspberry Pi and BeagleBone Black. **embd** is a hardware abstraction layer (HAL) for embedded systems.
It allows you to start your hardware hack on easily available hobby boards (like the Raspberry Pi, BeagleBone Black, etc.) by giving you staight forward access to the board's capabilities as well as a plethora of **sensors** (like accelerometers, gyroscopes, thermometers, etc.) and **controllers** (PWM generators, digital-to-analog convertors) for which we have written drivers. And when things get serious, you dont have to throw away the code. You carry forward the effort onto more custom designed boards where the HAL abstraction of EMBD will save you precious time.
