Beaglebone Black I/O Library Toolkit Manual.
=============================================================================================
GPIO CLK Status toolkit This toolkit show the GPIO clock module status of GPIO0 /GPIO1 / GPIO2 / GPIO3 .
Help for check GPIO clock module enable or not .
if GPIO clock is disable ,access pin in that will cause **"bus error"** message .
# make GPIO_STATUS
Expansion Header toolkit This toolkit show the "current" pins status of Expansion Header P8 and P9 ,
include Pin mode , pull-high/low .... etc .
# make EP_STATUS
ADC Argument Calculation toolkit This toolkit is a simple computer of ADC clock argument calculation ,
it calculate the Clock Divider / Open Delay / Sample Average for ADC module ,
and list all "Feasible Solution" of these three value to achieve the request frequency .
# make ADC_CALC
# ./ADC_CALC -f {request frequency} -t {frequency tolerance}
