## GPIO Access Modules

HiPi provides to modules that provide access to the Raspberry Pi GPIO registers directly by by wrapping an external C library.

### HiPi::BCM2835

The HiPi::BCM2835 module provides a Perl wrapper around Mike McCauley's bcm2835 C library.

Mike also provides his own Perl wrapper for the library - Device::BCM2835

### HiPi::BCM2835::I2C

A wrapper for the HiPi::BCM2835 I2C functions

### HiPi::Wiring

The HiPi::Wiring module is a thin wrapper around the excellent WiringPi library by Gordon Henderson. You can see full description and examples of using the library at:
