Factory Acceptance Test

Test Station Theory of Operations

Test Station controls the I2C interface on the UUT
Three tests
- Internal Test
- External Loopback Test
- Bounce an LED Test

Test Station Set-up

Uses ODAS Test Station V2
Unit Under Test (UUT)
Attach Host Computer USB to the Arduino NANO on the Test Station
Run puTTY on the Host Computer
- 9600 baud

Card Selection

puTTY will display the menu

Checking if EEPROM is present on UUT...EEPROM is not present on UUT
Count of I2C devices in range 0x20-0x27 on UUT = 1
Detected MCP23008
Select the board type (Other)
1 - I2CIO8 board
2 - I2CIO8X board
Select board >

Select 1

Init I2CIO-8 card
C=Card Tests, D=Direct, E=EEPROM, I=access Internal DIGIO32

Running Card Test

Select Card Tests = "C"
Select Run Tests = "T"
Move jumper across the 4 jumper pins H5-H8
LEDs will correspond
INT LED will blink on/off
Observe test results

C=Card Tests, D=Direct, E=EEPROM, I=access Internal DIGIO32
L=Loop/S=Single, T=Test, B=Bounce LEDs, I=UUT Int'l Tests, X=eXit sub-menu
Testing UUT = I2CIO-8
I2CIO8 card tests
Move jumper across H5-H8, observe LEDs D0-D3
Verify Int LED blinks
Hit a key to stop test
Test PASS = 1, FAIL = 0

Hit ENTER to display menu

L=Loop/S=Single, T=Test, B=Bounce LEDs, I=UUT Int'l Test, X=eXit sub-menu

Running Internal Tests

Remove loopback cable
Select Card Tests = "C"
Select Run Tests = "I"
Observe test results

L=Loop/S=Single, T=Test, B=Bounce LEDs, I=UUT Int'l Tests, X=eXit sub-menu
UUT Internal card tests
Test PASS = 2, FAIL = 0

Hit ENTER to display menu

L=Loop/S=Single, T=Test, B=Bounce LEDs, I=UUT Int'l Test, X=eXit sub-menu

Running Blink LED Test

Select Card Tests = "C"
Select Run Tests = "B"
Observe LEDs scanning on the 4 LEDs on the card

L=Loop/S=Single, T=Test, B=Bounce LEDs, I=UUT Int'l Test, X=eXit sub-menu
Bounce a bit across outputs
Bouncing LEDs I2CIO8 - any key to stop

Hit ENTER to display the menu

Finished bouncing LEDs
