Project Description

POST PRODUCTION SOFTWARE SUPPORT

I2C Audio Trigger and Switch Sensing Assembly

=====================================================================

POST PRODUCTION ACTIVITIES

1. Maintain the software and hardware configuration for testing.

2. Support repair of minor bugs and performance issues.

3. Respond to deficiency reports within 24 hours via email.

CIRCUIT DESCRIPTION

Using Arduino open source hardware and firmware platforms, the circuit sends and receives one byte of data when requested by the master under address 0x30. The received byte triggers the audio circuit to play predefined tones based on the bits set. When multiple bits are set, a prioritization determines which mp3 to play. The circuit also monitors 5 switch positions, and sends corresponding bit status to the I2C Master via one byte of data 12.5 times per second.

INPUT DATA

=================================

AuxInput[0] bit 0 = FIRE

AuxInput[0] bit 1 = BCU

AuxInput[0] bit 2 = ACTUATOR

AuxInput[0] bit 3 = NONE

AuxInput[0] bit 4 = IFF_INTERROGATE

AuxInput[0] bit 5 = NONE

AuxInput[0] bit 6 = UNCAGE

AuxInput[0] bit 7 = None

OUTPUT DATA

==================================

AuxOutput[0] = bit 0 = None

AuxOutput[0] = bit 1 = IFFunknown

AuxOutput[0] = bit 2 = IFFmode3

AuxOutput[0] = bit 3 = IFFmode4

AuxOutput[0] = bit 4 = Spinup

AuxOutput[0] = bit 5 = Acquisition

AuxOutput[0] = bit 6 = LockTone

AuxOutput[0] = bit 7 = BaseTone

TEST CONFIGURATION

1 Arduino Uno to simulate the master and to monitor data transfer.

1 Arduino Uno to test the code of the main board.

1 MP3 Trigger Board. PN WIG1102

1 SD card containing the audio tracks

5 switches connected to the main board to test sensing

1 computer with Arduino software to test code and monitor serial data.

Period of performance will be 2 months from award with monthly milestones.
