===== Milestone 3 =====

In this milestone you will implement most of the 'C' code that implements the laser-tag system.

==== Goal ====

Demonstrate the system working with a feedback connection (built into the ECEn Development Board) connecting the output of the transmitter to the input of the ADC. You will demonstrate the ability of your system to:
  * detect hits on each of the 10 frequencies,
  * no false detects,
  * no bouncing of the trigger switch, i.e., register one hit for each push/release of the trigger,
  * display the computed power of each of the channels on the TFT with the provided histogram package.

Here are a couple of videos that show what you will demonstrate after you complete these milestone. One of the videos demonstrates [[https://www.youtube.com/watch?v=MqfSMlpJvAc|continuous power mode]]. The other video demonstrates [[https://www.youtube.com/watch?v=PYiv2PgLo6k|shooter mode]]. I will provide the source code for the histogram display that you see in the videos.



==== Organization ====

This milestone will be divided into three tasks that will be due and passed off weekly.
  - [[Milestone 3 Task 1 | Task 1]]. Implementation and verification of the FIR and IIR filters (filter.c). Demonstrate all sets of of IIR coefficients.
  - [[Milestone 3 Task 2 | Task 2]]. Implementation of the transmitter state-machine (transmitter.c), the trigger state-machine (trigger.c), the hitLedTimer state-machine (hitLedTimer.c), the lockoutTimer state-machine (lockoutTimer.c), and the code to compute the power in the output from each IIR band-pass filter.
  - [[Milestone 3 Task 3 | Task 3]]. Implementation of the detector (detector.c) and integration with all other parts of the project in order to perform the final pass-off for the overall milestone using the feedback cable.
