Moduli Radio

Modulo Wixel basato sul microcontrollore CC2511F32 della Texas Instruments.
Wixel Configuration Utility
Per sfruttare le funzionalità wireless sono necessari 2 moduli Wixel.
 
Il Wixel come porta seriale senza fili
La “Wireless Serial App” trasforma una singolo Wixel in un adattatore USB-seriale e una coppia di Wixel in un collegamento seriale wireless USB / TTL per la comunicazione tra due microcontrollori ( come un collegamento XBee ) o tra un PC e un microcontrollore.
Controllo Wireless da PC di un robot utilizzando una coppia di Wixel
 
Permette la comunicazione senza fili tra un PC e un robot.
