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

LED-32-P426-720px.jpg

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

Test Station Connectors

  • USB on Pico
    • Not required if VGA, PS/2 are used
    • Used to download code
    • Alternate way to power the card
    • Can also run tests over this connection (mirrors PS/2, VGA)
  • LED-32 40-pin connector to monitor outputs from Digital I/O cards
  • J1 - I2C to UUT
  • J8 - Audio
  • J9 - VGA
  • J10 - USB Power
  • J11 - PS/2
  • P1 - DB-37 provides 32-bits of Digital I/O

Card stackup

  • 6-32 standoffs

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
Found device at 0x50
Personality EEPROM contents
 Signature = ODAS
 Version = 1
 Rsvd = 0
 NumAtoms = 2
 eeplen = 96
 uuid = 0000000000000000
 Product ID = 6 (DIGIO32-I2C)
 vslen = 32
 pslen = 32
 Vendor String = LAND-BOARDS.COM
 Product String = DIGIO32-I2C
Re-write (Y/N)?

Test Station Validation / Self-Test

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
