i using a pic18f452 for my accelerometer.Anyone know what value of crystal for my ocsilator is suitable.I need to calculate speed and distance using accelerometer.
 

Hi

That depend on the type of accelerometer you are using - whether you are using digital accelerometer the clock frequency not importent since reading the device is synchronicely done.
whether you r using an analog type and reading the data by measuring PWM signal or using A/D converter

My advice use the highest ferquency you can !

All the best
