Application Note
NOTE:
NodeX_Write Message Format
Broadcast_ Message Format
LED pattern sent with command byte. Pattern written to slave node
LEDs. IDENT and SLEEP commands the LED pattern is ignored.
NodeX_Read Message Format
The message format was adopted to allow flexibility within the demo.
Additional commands can be added without too much effort. The slaves
can also easily decode the various commands and act accordingly.
Another benefit is that the master node software has total control over
the LED pattern that the slaves output. In order to change the LED’s
sequence, only the master software has to be changed.
