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.
