C# GUI code to control Warren Stearn's FilpChip tester as modified for a SPI interface.
The USB/SPI cable is an FTDI C232HM-DDHSL-0. Digi-Key, Farnell, and Mouser usually have lots of them in stock for about $40. You can find technical details on the USB/SPI cable here: http://www.ftdichip.com/Products/Cables/USBMPSSE.htm
You must replace the standard Windows driver for the USB/SPI cable with the FTDI D2XX driver. You can download the Windows D2XX driver and installation guide here: http://www.ftdichip.com/Drivers/D2XX.htm
The FTDI LibMPSSE-SPI library provides the SPI protocol for this application. A wrapper library provides an interface between this managed code application and the LibMPSSE-SPI library. Both the libMPSSE.dll and libMPSSEWrapper.dll files need to be in the same directory as the Warrens_Flipchip_Tester.exe file.
The FlipChip Tester needs to be supplied with +5V to power the FlipChip and the SPI GPIO chips.
The toggle switch needs to be set towards the right to enable +5V power to the FlipChip. The amber LED will illuminate when the +5V power to the FlipChip is on. You should turn off the +5V when installing or removing a FlipChip.
The Green LED will turn on at the beginning of a test, and will stay on as long as no faults are found. The Yellow LED will illuminate when a test is running. The Red LED will illuminate if a fault is found during a test.
