Basically, you wire interface DVFS of component DVFSC (defined in tinyos-1.x/tos/platform/imote2/DVFSC.nc) and make the following call:
call DVFS.SwitchCoreFreq(416,208); //call DVFS.SwitchCoreFreq(208,208); //call DVFS.SwitchCoreFreq(104,104); // Change the CPU and bus frequencies to 104MHz. This // also changes the voltage to the minimum amount needed // to support this speed. // // This was copied from: // contrib/imote2/test/TestSensorboard\TestSensorboardM.nc // // DVFS is defined in: // tinyos-1.x/tos/platform/imote2/DVFSC.nc
