formula depends upon type of sensor.analog,digital?
if analog..what is the sensitivity and FSR of the device.what signal conditioning between the sensor and the PIC.
Speed of the sensor ?

All of this is in the datasheet of the sensor from the manufacturer.

As for CCS C code you might try Google....seems there's a few thousand 'hits' about the device.....

Now if you supply me with 6 pieces of the device I'll be more than happy to cut a 'driver' for you.
