Can you elaborate a litle about what parts are running in the beagle and what in the FPGA. I presume you have a non RT HAL module to interface the 7i43 through the USB port, haven't you?. I didn't know such kind things could be done using FPGA, although I think they must be really difficult and laborious. I'm really impressed. Javier PD: Isn't this an answer to the survival of LinuxCNC without a Linux RT (RTAI Xenomai or other alternative), and even to the latency killer hardware?. A posssible path to its extension to other OS? ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
