The joint test action group (JTAG)-SMT2 is a compact, complete and fully self-contained surface-mount programming module for Xilinx® field-programmable gate arrays (FPGAs). The module can be accessed directly from all Xilinx tools, including iMPACT™, ChipScope™, and EDK. The JTAG-SMT2 uses a 3.3V main power supply and a separate Vref supply to drive the JTAG signals. All JTAG signals use high speed, 24mA, three-state buffers that allow signal voltages from 1.8V to 5V and bus speeds of up to 30MBit/sec. The module uses a standard Type-A to Micro-USB cable available for purchase from Digilent, Inc.

The PmodAD1 is an analog-to-digital converter module powered by the Analog Devices AD7476A. Users can simultaneously receive 12 bits of resolution for 2 individual channels at up to 1 MSPS by communicating with the module through an interface similar to SPI.
For those keeping score at home, that's one RPi 1B and five 3s, inside some of the multipi thingies from modmypi.com. Why the one 1B? Because I still had it lying around. The five 3s are brand new though :-)
Also, yes, the GPIOs on the 1B are somewhat bent. Please ignore :-)

The PmodRJ45 connector modules can offer an extended wired connection between two different systems. Shipped as a pair of male and female modules, users can connect the two together with a classic "ethernet cable" to communicate via the ethernet protocol or as simple GPIO lines.
The PmodTPH2 offers 12 external pin headers so that users can easily test the GPIO signals passing through each of the pins.
The PmodAD1 is an analog-to-digital converter module powered by the Analog Devices AD7476A. Users can simultaneously receive 12 bits of resolution for 2 individual channels at up to 1 MSPS by communicating with the module through an interface similar to SPI.

The scope probe is jabbed into the Chip Select / Write Enable strobe on the EvGNibBus (pronounced 'evnibus', like omnibus), on the PIC that connects to PIANA Performer 0.
The 128us interval is 8 single byte write cycles to each of 8 PIANA Performer nodes. A single write is 16 us, given by a 12us low nibble time (which has to account for PIC interrupt latency and some checks before the nibble is strobed in) then 4us of high nibble time (the ISR just sits and spins on CS, waiting for it to go low before it captures the nibble).
This will absolutely torch the CPU on the Conductor Pi. It will evaporate at least 35% of my CPU cycles as it needs to sit in a busy loop in a high priority thread. But once it's up and running I can experiment with how badly it suffers from running lower down in the priority queue, I may be able to get away with some nasty lash up, but it will always have to be a busy loop and it will always have to run at higher priority than the OpenGL thread.
But I might be able to buy something back, time will tell.
Playing around with the GPIO with Python. SO has a lot more understanding of the electrical stuff that I do. Oscium oscilloscope on the iPad.

The most interesting part of this unit, this board is common to most modern Ferrograph displays, including public transport information displays. It is far more sophisticated than the good old FDS-101 that I am used to working with, and is based on a H8 microcontroller, with 1MB flash and 128KB RAM; message data is presumably stored in the flash for non-volatility. The DIP switches can be accessed through a hole in the rear of the casing, but other controls and displays are hidden, so once assembled, you cannot access the reset button or the 7 segment display or comms LEDs.
The board provides lots of interfaces, including both external and internal temperature sensors, ambient light photocell, impact sensor (to detect vandals beating the hell out of the unit, I presume), several comms ports, GPIO, and even an unpopulated audio amplifier section. There's also a handy diagnostic 7 segment display and LEDs for comms activity (though the TX LED indicates data being received by the unit, and the RX LED presumably indicates data being sent). In this particular unit, there is no battery fitted for the RTCC, and the temperature sensor calibration pots are also omitted, as they are presumably not used for this internal display.
The PmodKYPD is a 16-button keypad arranged in a hexidecimal format (0-F). By digitally driving a column line to a logic low level and digitally reading each of the rows, users can determine which button is currently pressed.
