Misc Configuration

Command Operation
TRD? Query the board temperature.
CFG? Query all configuration settings.
VER? Query the PIC32 and FPGA firmware version.
IOD? Query the IO Address decoding range (or width).
SnR? Query the reset state of the Module Sockets
IOD=v Set the IO Address decoding width.
SnR=v Set the reset state of the Module Sockets
UPD Write configuration changes to Non-Volatile storage

IO Address Ranges set with IOD command

The IO Address range depends on the IO Address decoding width.

Testing / Debugging

A couple of commands are available that directly write or read the FPGA registers that are accessed via an SPI
port between the PIC32 and the FPGA.
Command Operation
SPIR reg Perform an SPI read operation from the indicated register.
SPIW reg value Perform an SPI write operation to the indicated register.

Notes
Value return is degrees Kelvin
PIC32 firmware version appears as "Vx.y"
FPGA version appears as a letter "A", "B", "C", etc.
v = 10, 11 or 12
=10 performs "10-bit" IO decoding.
=11 performs "11-bit" IO decoding.
=12 performs "12-bit" IO decoding.
v = 'Y' to Assert the reset
'N' to De-assert reset
n = 1 = Apply to Socket #1
2 = Apply to Socket #2

Notes
reg is a decimal number 0 to N
reg is a decimal number 0 to N
value is a 16 bit HEX number as appropriate
for the register.
