Starter Kit Demo
2.2.4
External Sensor Interface
The starter kit features an analog conditioning circuit which can be used by the user to
plug in a wide range of external sensors. The differential output of the sensor flows
through a differential amplifier and an anti-aliasing filter before being sampled by the
on-chip ADC.
2.3
OTHER DEMO CODE EXAMPLES
The starter kit software CD includes another demo code example,
External_Sensor_Demo.
The External_Sensor_Demo code example demonstrates the low-cost sensor signal
capture and processing. When a sensor is plugged into the analog conditioning
circuitry the code example captures the sensor signal through the ADC channel. The
captured discrete time sensor signal can be processed inside the code example.
Instructions are provided in the source file as to where user desired signal processing
routines need to be added to process the sensor signal captured by the ADC.
The characteristics of the external analog sensor that can be used are provided in
