Hi Miller,

Did this extern and blog happen beyond the extern found in:
http://crca.ucsd.edu/~msp/syllabi/206.13w/index.htm
?

I can get this one to load, but not to open the gpio.

If I send 
[open 1( 
to 
[gpio 4]
I get the error
/sys/class/gpio/gpio4/value: No such file or directory
in the console

best,

J
