- 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
