sir i m working on monitoring and control system for wsn using telosb
mote....... i have 2 motes and 1 base station.... these 2 motes monitor
temperature and humidity and sent to base station ...... my monitoring part is
complete and i m getting values of temperature and humidity in java
application now i want to send my these coming temperature and humidity
values to relays through parallel interface......
mye code is written below i need parallel interface code where i write
/*\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\
/* need parallel interface code to send these temperature and humidty
values to relays( external hardware)
*/
