## Projects

### [FMC DEL 1ns 4cha - stand-alone application](https://www.ohwr.org/project/fmc-delay-1ns-8cha-sa)
A fully operational stand-alone [FMC Delay
card](https://www.ohwr.org/project/fmc-delay-1ns-8cha/wiki) based
White-Rabbit node which can be initialized and perform periodic
calibrations without requiring to be plugged on a PC, reducing final
system cost, size and power consumption.  
[More info at the Wiki
page](https://www.ohwr.org/project/fmc-delay-1ns-8cha-sa/wiki)


### [White Rabbit Standardization](https://www.ohwr.org/project/wr-std)
This project covers all efforts geared to standardize White Rabbit, with
a view to providing a stable specification which everyone can use to
build compliant products.


### [Simple PCIe FMC carrier (SPEC) - Software](https://www.ohwr.org/project/spec-sw)
Software support for the SPEC board, including kernel and user-space
Linux code.  
The package also include the fmc-bus driver, which is expected to be
used by other carriers as well.


### [White Rabbit Switch - Software](https://www.ohwr.org/project/wr-switch-sw)
Development of software for the White Rabbit switch, and in particular
the embedded Linux system running in the ARM9 processor.  
[More info at the Wiki
page](https://www.ohwr.org/project/wr-switch-sw/wiki)


### [FMC TDC 1ns 5cha](https://www.ohwr.org/project/fmc-tdc)
An FPGA Mezzanine Card (FMC) with a Time to Digital Converter chip to
perform one-shot sub-nanosecond time interval measurements. Commercially
available.  
[More info at the Wiki page](https://www.ohwr.org/project/fmc-tdc/wiki)


### [SPEC box 1 Node](https://www.ohwr.org/project/spec-box-1n)
The spec-box-1n allows to use a SPEC FMC carrier in stand-alone mode,
not plugged inside a PC.  
An external 12 volt supply should be used to power the box. There is no
forced ventilation in the box.  
[More info at the Wiki
page](https://www.ohwr.org/project/spec-box-1n/wiki)


### [Simple PCIe FMC carrier (SPEC)](https://www.ohwr.org/project/spec)
A simple 4-lane PCIe carrier for a low pin count FPGA Mezzanine Card
(VITA 57). It supports the White Rabbit timing and control network.
Commercially available. Linux and Labview drivers available for some
mezzanine cards.  
[More info at the Wiki page](https://www.ohwr.org/project/spec/wiki)


### [FMC DIO 5ch TTL a](https://www.ohwr.org/project/fmc-dio-5chttla)
FmcDIO5chTTLa is a 5-bit port digital IO card in FMC form-factor. Each
single-bit port can be configured individually as input or output. The
I/Os on LEMO 00 connectors are TTL compatible. Commercially available.  
[More info at the Wiki
page](https://www.ohwr.org/project/fmc-dio-5chttla/wiki)


### [FMC ADC 125M 14b 12ch - DAC 1250M 16b 2ch](https://www.ohwr.org/project/fmc-adc125m14b12ch-dac1250m16b2ch)
The fmc-adc125m14b12ch-dac1250m16b2ch (fmc-dad) board is a 12 ch ADC/ 2
ch DAC channels board using FMC HPC and QSE connectors It has been
designed for system requiring a feedback loop mechanism with precise
timing, such as the tunning of RF cavities.  
[More info at the Wiki
page](https://www.ohwr.org/project/fmc-adc125m14b12ch-dac1250m16b2ch/wiki)


### [White Rabbit Starting Kit](https://www.ohwr.org/project/wr-starting-kit)
This project guides new users to start in the White Rabbit “World” with
simple experiments. The starting kit uses two SPEC + FMC-DIO cards. Each
node allows basic operations such as input timestamping or programmable
output pulse generation. Additionally, specific software and gateware
layers allow to use it as a standard network interface card implementing
the White Rabbit technology functionalities.


### [Wishbone Serializer Core](https://www.ohwr.org/project/wb-serializer-core)
A transparent Wishbone bridge between two FPGAs using high-speed serial
links.  
*This project is on hold.**  
[More info at the Wiki
page](https://www.ohwr.org/project/wb-serializer-core/wiki)


### [White Rabbit Network Interface Card](https://www.ohwr.org/project/wr-nic)
A White Rabbit compliant Network Interface Card (NIC) based on the
[SPEC](https://www.ohwr.org/project/spec/wiki) and the [DIO
FMC](https://www.ohwr.org/project/fmc-dio-5chttla/wiki). This project
hosts the HDL and associated software to configure the SPEC so it
behaves as a NIC under the Linux OS.


### [SPEC Box 3 Nodes (Rack 19")](https://www.ohwr.org/project/spec-box-3n)
The spec-box-3n allows to use up to three SPEC FMC carriers in
stand-alone mode, not plugged inside a PC.  
An internal 230V supply module powers the SPEC boards. The box contains
fans to cool the cards.
