The 'standard' Hostmot-4 config that most people use has four main hardware encoder counters (like you describe above), and four secondary encoder counters (see the pinout in the manual). You could connect your jogwheel A/B-quadrature signals to any of these hardware encoder counters. Your HAL code will then look a bit different from what I have on my blog. I connected the A/B signals to standard IO and used the HAL software encoder counter component. That works fine too, since the pulse rate from my jogwheel (100ppr) never exceeds 1 kHz or so (the encoder counter HAL component needs hooked up to a thread which updates at maybe 10kHz) > 6 and 4 position switches and 4 push type switches should be connected to I/O > area of 5i20. > Am I right? Yes. Any of the 16 inputs on the two IO connectors will do, you just have to remember where they are when you start HAL programming. Anders PS: someone should make a really cool pyvcp m5i20 test panel (hostmot-4 to start with). I think tomp already did something, is it in cvs yet? PS2: the integrator manual should contain case studies of the whole electrical + HAL wiring for machines that EMCers have converted. I'll try to contribute my own stuff in a month or so. Something like this: http://www.anderswallin.net/sandbox/servo.pdf along with HAL (net2dot images + descriptions) ------------------------------------------------------------------------- Take Surveys.
