Beaglebone black I/O library , using Memory mapped I/O
Simple C I/O library of Beaglebone balck
============================ Hi , everyone
I'm very very sorry. I'm not able to preserve of BBBiolib for private issues.
I'will freezing update for 1 years.
With my deepest regret. Meng-Lun, Cai
===========================
V1 October 2013 - shabaz (iolib) : create basic library
V2 October 2013 - shabaz (iolib) : fix some BUG
V2.1 November.7 2013 - add some comment and modify function name
V2.2 November.10 2013 - add GPIO Enable/Disable function (GPIO 1~3)
V2.3 November.19 2013 - add GPIO Enable/Disable function (GPIO 0)
V2.4 November.23 2013 - add whole GPIO control function (I/O and direction set)
V2.5 December.7 2013 - change directory architecture ,add Demo/ and Toolkit/ directory .
V2.6 December.9 2013 - add simple ePWM module control function in am335x
V2.7 December.20 2013 - add simple McSPI control function .
V2.8 March.14 2014 - add ADC application of Arduino Microphone module ,
and ADC argument calculation toolkit .
Freezing March 11 2014 .
=============================================================================================
this library support simple I/O for beaglebone black ,using C .
Demo Directory include some demo basic this library ,each circuit layout ,picture and document in file directory .

overlays
BBBIO include some device tree overlays example for linux kernel 3.8.13 .
compile each overlays:
#cd overlay
#make
Install overlays
#cd overlay
#make install
apply overlay :
#cp {OVERLAY} /lib/firmware/
#echo {OVERLAY's part-number} >> /sys/devices/bone_capemgr.*/slots
overlays list :
1. EHRPWM 0~3 overlay
#echo BBBIO-EHRPWM >> /sys/devices/bone_capemgr.*/slots
2. SPI 1 overlays
#echo BBBIO-SPI1 >> /sys/devices/bone_capemgr.*/slots
