Directional Tap with FIFO application
The Directional Tap Application demo evaluates the built-in algorithm for detecting pulses in conjunction
with the FIFO. You can evaluate Freescale’s default configuration and modify those settings to tailor a
demonstration for your target application.
This demo includes MCU-status and estimated-current displays, which enable you to demonstrate the
device’s power-saving sleep mode feature.
4.8.1
Active screen
The Active screen contains a set of indicators that change to green when a tap is detected. It also has a
graph displaying the data stored in the FIFO, displays that show the MCU status, an estimate of used
current, and the direction of the last tap.
Note:
Before changing any of the Active screen’s
settings, select the Standby option button.
