Reply from off list: ~~~~~~~~~~~ Thanks for the information Joachim. The first bits of my plan are on the wiki, here: http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?AVR Anyone that would like to correct or add designs or software to this page, please feel free to do so: http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?BasicSteps The main theme is to use the data rich but speed poor parallel port to feed a speed rich AVR using EPP, with very low latency, in an open and DIY friendly way. The ATxmega runs on 3.6V max, so my current task is to design a parallel port interface that can use 3 to 5V in, and feed ~3V to the xmega. After the data link is worked out, the xmega can be used to produce a wide range of signals (step/dir, PWM, 3-phase) and capture input (encoders, ADC). If there is enough interest, it might be worth while to have a batch of PC boards made and/or maintain a parts list or kits. -- Kirk Wallace http://www.wallacecompany.com/machine_shop/ http://www.wallacecompany.com/E45/index.html California, USA ------------------------------------------------------------------------------ Protect Your Site and Customers from Malware Attacks Learn about various malware tactics and how to avoid them.
