- C library for Broadcom BCM 2835 as used in Raspberry Pi.
- It provides access to GPIO and other IO functions on the
- Broadcom BCM 2835 chip, allowing access to the GPIO pins
- on the 26 pin IDE plug on the RPi board so you can control
- and interface with various external devices.
- WARNING: the opinion of the Buildroot developers is that
- such library is a complete abomination as it entirely works
- around the standard Linux interfaces to access GPIOs, I2C,
- SPI busses or other IOs. The library directly remaps the
- hardware registers in user-space, completely bypassing what
- the kernel drivers are doing, and potentially conflicting
- with them.
