diff include/Utilities.h @ 18:31503d9de101 matrix_gpio

- digitalWrite and analogWrite macros are now persistent: they write a value on the given channel from the current frame to the end of the buffer. When
this is not needed you can use digitalWriteFrame and analogWriteFrame instead.
- included the matrix_gpio_demo code
- the Eclipe project is somehow broken
