BBBiolib

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 .

Hotw to use :

    Build libBBBio.a :

            # make

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
