So, thanks to an assist from Jeff Epler and Chris Radek, I've gotten my Arduino->HAL interface more or less fully functional with both inputs and outputs. My purpose for this is to build a human-machine interface (read: control panel for my mill). So far I've gotten it to turn input pins in HALUI on and off, and turn external LEDs on and off based on the status of output pins.
What I'm wondering about is how best to work an encoder into this. Currently, the way I'm doing it is to have the arduino read the encoder outputs and convert them to a signal which represents one pulse in the CW or CCW direction. The Python script receives the signal, and then jogs the appropriate axis in the + or - direction for 1/10th of a second. So far, the motion seems smooth (on screen, I haven't tried it on one of my machines yet), but I'm wondering if there's a better way. The catch is that I'd like to keep this on the serial connection, both to save the parallel port pins, and also for the elegance of being able to do everything over the Arduino's USB cable. ------------------------------------------------------------------------------ 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 Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
