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.

Organization

This milestone will be divided into three tasks that will be due and passed off as recorded in Learning Suite.

  1. Task 1. Implementation and verification of the FIR and IIR filters (filter.c). Demonstrate all sets of IIR coefficients.
  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.
  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 provided by the development board.

Software Coding Standard

All of the tasks comprising Milestone 3 are software tasks and must adhere to the coding standard.

See learning suite for a breakdown of the credit that you receive for pass-off and source-code submission.
