I've been looking at this a bit recently. Pictures here: http://jks.com
I run the 5370 firmware on an m6800 emulator written in C running on a Linux box. Reads and writes to I/O space are caught and executed on the 5370 hardware via an interface board hooked up to the m6800 processor bus. This interface board is a cheap USB to 32-bit parallel adapter card (Dimax sub-20). I used an evaluation board for the Analog Devices ADuM4160 USB power/signal isolator chip. The next step is to move everything to a microcontroller (e.g. SAM7X) on a card that replaces the processor board completely. As has been mentioned you can do all sorts of crazy, and perhaps useful, stuff at this point. ~~~ I have a question about the dead time of the 5370. Can it be eliminated with a fast enough processor, buffering, interface, etc. or is it intrinsic to the measurement hardware itself? _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
