CRIO-WR is originally derived from and keeps firmware compatibly with
|
|
|
the [SPEC](https://www.ohwr.org/project/spec/wiki) /
|
|
|
[CUTE-WR](https://www.ohwr.org/project/cute-wr/wiki) boards. The
|
|
|
connector at the front panel provides 10 user I/O signals, connected
|
|
|
directly to the FPGA (i.e. programmable as input/output, LVDS/CMOS,
|
|
|
SERDES etc.). The module is connected over SPI to the CompactRIO
|
|
|
backplane/chassis/controller. The functionality in Labview is for
|
|
|
example:
|
|
|
CRIO-WR is originally derived from and keeps maximum firmware compatibly
|
|
|
with the established boards
|
|
|
[SPEC](https://www.ohwr.org/project/spec/wiki) and
|
|
|
[CUTE-WR](https://www.ohwr.org/project/cute-wr/wiki). CRIO-WR is based
|
|
|
on a FPGA with WR PTP Core plus required hardware to implement a
|
|
|
standalone WR node.
|
|
|
|
|
|
- Read status of WR-link
|
|
|
- Read validity of WR-timecode
|
|
|
- Read externally triggered WR-timestamps
|
|
|
- Generate output pulses based on
|
|
|
WR-timecode
|
|
|
The CompactRIO functionality is ensured by a dedicated power supply with
|
|
|
sleep-mode, a separate EEPROM, an SPI plus some glue logic in the FPGA's
|
|
|
CRIO User Core. A connector at the front panel provides 10 user I/O
|
|
|
signals (protected by TVS), connected directly to the FPGA (programmable
|
|
|
as input/output, LVDS/CMOS, SERDES
|
|
|
etc.)
