I've been playing around with this a bit. My plan was to build a simple board that read encoder signals, and outputted a PWM signal. I'm aiming for the 1ms update. I've built an implementation (a poor one) of RT-Net that runs on a atmel NGW100 demo board. The Ethernet part mostly worked, but I wasn't able to read the encoders and generate the PWM signals fast enough. I just ordered a XMOS XC-2 ethernet development kit. The XMOS CPU has 4 cores with 8 threads each and sample Ethernet source code. Hopefully the one chip can do it all. ------------------------------------------------------------------------------ Start uncovering the many advantages of virtual appliances and start using them to simplify application deployment and accelerate your shift to cloud computing. http://p.sf.net/sfu/novell-sfdev2dev _______________________________________________ Emc-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-users
