## x_simple.c

* In a text editor, open *x_simple.c*. Find the GOpen() call and update the address to match the desired hardware. See the documentation for GOpen() for address formatting options. 

### Compile

    $ gcc -Wall -Werror x_simple.c -lgclib -lgclibo -o simple

## x_examples.cpp
* In a text editor, open *x_examples.cpp*. Find the GOpen() call and update the address to match the desired hardware. See the documentation for GOpen() for address formatting options. Don't forget `-s ALL` if data records, interrupts, and messages are to be tested.
* Find the `#if 0` preprocessor block enclosing the example calls. Change to `#if 1` to run the examples. Comment out the function calls to be avoided. Note some calls attempt to move motors and not all functions are compatible with all Galil products.

### Compile

    $ g++ x_*.cpp -lgclib -lgclibo -o example
