Guzunty Pi gz_test resulsts looks OK

Now I have connected the RPi P1-07 signal GPCLK0 to the Guzunty Pi's corresponding 26 pin plug pin 07.
Then the scope displayed what I expected, at FB1MC2, a GPCLK0 divided down signal.

So far so good.

Next step I think is to check how the C program does the job.  Perhaps I can port it to Python.

There is one thing I need to know, that is the Make file.  Before RPi, I have been playing with Arduino and Netduino for a couple of years.  I remember I did not make any file, but just click "build" and the C++/C# program will compile and run.  But now RPi uses make which I need to check out what does the make file do, I guess it is compile and link.
