This fixes the problem of detecting if pins 74-77 are available for gpio/spi use. These pins were sown to be used by the emmc, but actually used by the sound pcm. If the sound PCM is disabled and the emmc is enabled the pinse can now be used. mraa-gpio list output Pins 74-77
73 GPIO115: GPIO
74 GPIO113: GPIO SPI
75 GPIO111: GPIO SPI
76 GPIO112: GPIO SPI
77 GPIO110: GPIO SPI
to build:
1. clone repo
2. sudo apt-get install build-essential python-dev cmake automake libpcre3 libpcre3-dev byacc flex swig3.0
3. cd mraa, mkdir build, cd build
4. cmake -D CMAKE_INSTALL_PREFIX=/usr ..
5. make
6. sudo make install
This has been verified to work on BBGW, and BBBW with 9.0-9.5 with emmc enabled and PCM aduio turned off. It is so nice to have control of these pins when running with out an SD card.
