libpruio

Welcome to libpruio library,

- a driver for ARM33xx micro processors,
- developed on Beaglebone hardware, supporting
- analog input and
- digital input and output features.

It's designed for easy configuration and data handling at high speed. libpruio software runs on the host (ARM) and in parallel on a Programmable Realtime Unit SubSystem (= PRUSS or just PRU) and controls the subsystems

- Control Module
- GPIO: General Purpose Input / Output,
- PWMSS: Pulse-Width Modulation Subsystem,
- TSC_ADC_SS: Touch Screen Controler and Analog-to-Digital Convertor SubSystem (or just ADC).

The driver supports three run modi

- IO mode: digital and analog lines, timing conrolled by the host,
- RB mode: digital and analog lines, accurate ADC timing conrolled by the PRU,
- MM mode: analog lines and optional triggers, accurate ADC timing controlled by the PRU.

The libpruio library is developed and tested on a Beaglebone Black under Ubuntu 13.10 and Debian Image 2014-08-05. It should run on all Beaglebone platforms with Debian based LINUX operating system. It's compiled by the FreeBasic compiler. A wrapper for C programming language is included.
