In the past I have used Ethernet and USB to capture data from various devices to a PC. I am having to connect a fair number of devices that require some substantial buffering and processing first (i.e.: 500+ MB).
To simplify the project I am looking at connecting my technology to the LPC buses found inside P4 (modern) computers. This appears to be an excellent interface to transfer data quickly to a PC. The other option is to use a PCI DAQ card and capture all data that way.
Has anyone here successfully interfaced their projects to the LPC bus inside a P4 system (like a HP Evo)?
I would appreciate any feedback.
I have been able to determine that I would need some kind of strobe line to control when my device communicates on the LPC bus. I believe this is done now via a GPIO line on the Intel chipset. Again, any info or experience you may have with this would be helpful.
