Terry, The new m5i20 and Mesa drivers in general are much more flexible than the old m5i20 driver. If you look at configs/hm2-servos/5i20.ini, you will see the following at the beginning of the file:
DRIVER=hm2_pci BOARD=5i20 CONFIG="firmware=hm2/5i20/SVST8_4.BIT num_encoders=3 num_pwmgens=3 num_stepgens=0" This maps through to hm2-servo.hal, specifically the line: loadrt [HOSTMOT2](DRIVER) config=[HOSTMOT2](CONFIG) The first two lines are obvious. The third line is specifying how many of each component type to allocate. The P2 and P3 connectors are basically the same except for the channel number, because both can be interfaced with boards such as the m7i33 for encoders and analog reference signals for the servo amplifiers. Thus up to 8 motors and encoders can be handled by a single m5i20 if you have a configuration needing that many channels. If you have fewer, then the pins corresponding to the unused channels may be used as general purpose I/O. The sample configuration only uses 3 pwm generators and encoders, thus 6 pins are available on the P2 connector for gpio (25, 27, 33, 37, 41, 45) and all 24 pins on P3 are available for gpio. Each gpio may be configured as either input or output. After loading a configuration, do dmesg to see the actual pin assignments and pin names. Regards, Eric As I was looking through the SVST8_4IM2.pin file I saw that the connections for P2 are almost the same but P3 is alot different than the origional mi520. Do I make a new hal.io file for my machine and that will override the pinout that is listed for P3 in the SVST8_4IM2.bit file? I would then call this new .io file from the .ini file? A little direction here and I wont bother you guys anymore.The last statement was probably inaccurate. ------------------------------------------------------------------------------ Register Now for Creativity and Technology (CaT), June 3rd, NYC.
