== 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 ===

[[file:PiPicoMite-02_P18268_720px.jpg]]

* 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 ===

[[file: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

[[file:PiPicoMite02_Test_Station_Diag_USB-720px.jpg]]

== 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

<pre>
chdir "/lbcards/ODAS_EEPROM"
load "ODASEEPROM.bas"
run
</pre>
* Typical response if the card is already programmed
<pre>

== Test Station Validation / Self-Test ==

* [[PiPicoMite02]] Test Station cards
** [[PiPicoMite02]]
** [[LED-32]]
* [[DB37RIBBON]] card
* Cable set
** Same cable set used with [[DIGIO32-I2C#Card_Test_Procedure|DIGIO32-I2C]]
** (2) 10x2 ribbon cables
** Marking 1 DB37, 21 DB38 on one end, 1 LED32, 21 LED32 on the other end

** Bounces a bit across the LEDs
* Type
<pre>
chdir "/lbcards/GPIO32"
load "GPIO32-01.bas"
run
</pre>
* Will do 55, aa pattern alternating
* Will bounce a bit across the LEDs
* Hit any key to contines
