PiPicoMite02 Based Test Station

Hardware

• PiPicoMite02 Processor Card
• LED-32
• UUT Cables Set
• PS/2 keyboard
• VGA Monitor
• SD card with Test Code
• 5V into USB B or power card with USB Micro on Pico
• (4) Short standoffs below PiPicoMite02 Processor Card
• (2) "Medium" standoffs on end of board with DB-37
• LED-32 mounted above PiPicoMite02 Processor Card

PiPicoMite02 Processor Card

• Test code is stored on SD Card
• External I2C cards connect to J1 - I2C0 connector
• DB-37 to connect to external test cards

LED-32 Card

• 32 LEDs
• 8 Ground pins
• Connect with Ribbon Cables

Card stackup

• 6-32 standoffs

Cable Sets

• Ribbon cables
• Connect directly to LED-32 card or to DB37RIBBON card(s)
• UUT = I2CIO16-DB25 example

Program UUT EEPROM

• Some UUTs have Personality EEPROMs
• Run

chdir "/lbcards/ODAS_EEPROM"
load "ODASEEPROM.bas"
run

• Typical response if the card is already programmed

Test Station Validation / Self-Test

• PiPicoMite02 Test Station cards
  • PiPicoMite02
  • LED-32
• DB37RIBBON card
• Cable set
  • Same cable set used with DIGIO32-I2C
  • (2) 10x2 ribbon cables
  • Marking 1 DB37, 21 DB38 on one end, 1 LED32, 21 LED32 on the other end
• GPIO32-01.bas - test software
  • Bounces a bit across the LEDs
• Type

chdir "/lbcards/GPIO32"
load "GPIO32-01.bas"
run

• Will do 55, aa pattern alternating
• Will bounce a bit across the LEDs
• Hit any key to contines
