Contents
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
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
Cable Sets
- Ribbon cables
- Connect directly to LED-32 card or to DB37RIBBON card(s)
- UUT is 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
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
- PiPicoMite02 Test Station cards
- 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
