Hi,

typedef struct {
unsigned int type : 5;
unsigned int bit:3;
} ustruct;

ustruct bye;

Is this assignment correct if i have to set 3 bits?

Thanks for time wayne.............

When interfaced to RS232 it hangs after sending the control commands( i am not using UART for this). ie the LED glows forever...and doesn't excute the led off l ...

thanks for your time......

Thanks RLScott for your time.............

Here is one way: Start 38kHz PWM at 50% duty cycle and set Timer 0 to interrupt you in approximately 12.5 PWM periods of time (328 uSec). When you get ...

Thanks Rohit for your time...............

I am sorry......didn't put the entire code

I have connected an IR LED to the CCP1 pin(Pin B3) gate of FET .......Is this correct way? Can anyone give ...
