[flow] is a little disillusioned with commercial Data Acquisition Systems (DAQs) and channeled his frustration into his own, very cool, FPGA based solution.
The project takes form as a back plane into which various cards can be slotted. The the interface is just a PCI-e connector. If you need analog input, simply insert the card for it. Ethernet output? Same process. Modularity and expandability are the themes here.
[flow] already has projects in mind for his new DAQ. He’s using it to build an inverted pendulum. However, his planned cards really show the possibilities, anything from a logic analyzer card to an HDMI Output card allow for a wide array of configurations. There is also a small suite of tools which makes this process relatively easy to manage.
We can definitely see this evolving into a useful tool on our bench for prototyping.
Wow a card allowing HDMI output from a PCI-e bus, wherever would you get one of those?!?
It isn’t a PCI-e bus … its PCIe physical connectors. For HDMI output it is certainly just an FPGA dedicated to doing that on the FBUS.
This seems very, very, very similar to how National Instruments systems work.
what is the maximum bandwidth possible?
