Concurrent, synchronized acquisition from Imec and NI-DAQ devices.
Topics:
There are three branches in this repo separately supporting the three Imec Neuropixels project development phases. The three phases have mutually incompatible hardware and software, so obtain the appropriate materials for your needs. Release software packages are labeled as phase3A, phase3B1, or phase3B2. All early releases having no phase label are actually phase3A. All releases support NI-DAQ based acquisition.
Phase3A: Initially, 4 flavors of prototype probe (option 1, 2, 3, 4) were created enabling consortium members to choose the most useful architecture and feature set. Phase3A probes are connected one at a time to a Xilinx Kintex 7 FPGA board, and accessed via Ethernet. The probes, cables, HS and BSC parts are specific to phase3A.
Phase3B1: At this phase, option 3 probes had won and were further developed for commercial production. The same Xilinx board is retained for one at a time probe operation over Ethernet (but reprogrammed for 3B1). The cables, HS and BSC parts are all specific to 3B1. The 3B probes can be run with either 3B1 or 3B2 setups.
Phase3B2 (master code branch): This phase replaces the Xilinx board with PXIe based modules, each of which connects up to 4 probes. Several modules can be operated together from one PXI chassis and one application. The probes are the same as the phase3B1, but all other hardware parts are specific to the PXIe implementation.
Requirements differ according to platform:

Terminology: 'Enclustra' is a company that markets other vendor's FPGAs along with development and support tools. There are several FPGAs used in the Neuropixels hardware, including a Xilinx Zynq model, often referred to as 'the enclustra'.
GblDmx is a command-line tool that applies the global demuxed CAR filter to a specified binary file.
