Is there a sample hal file available for SPINX1 ?

Will the Mesa SPINX1 spindle control board work with a software pwmgen component?

Do I need to set pwmgen.0.pwm-freq ?

Here is what I have so far--no movement happens, yet, when I command the spindle to start.


loadrt pwmgen output_type=1
addf pwmgen.update servo-thread
addf pwmgen.make-pulses servo-thread
net spindle-speed-cmd motion.spindle-speed-out => pwmgen.0.value
net spindle-on motion.spindle-on => pwmgen.0.enable
net spindle-pwm pwmgen.0.pwm => hm2_5i25.0.7i84.0.1.output-02 #to PWM on spinx1############################
# Set the spindle's top speed in RPM
setp pwmgen.0.scale 1800


#net spindle-enable => hm2_5i25.0.7i84.0.1.output-01 ##enable spinx1#this is not right, I think I need to connect the enable pin to ground

net spindle-fwd motion.spindle-forward => hm2_5i25.0.7i84.0.1.output-00 #on is forward##off is reverse####


#net spindle-rev motion.spindle-reverse => parport.0.pin-17-out

The SPINX1 expects TTL level signals so will likely not work well with 7I84 outputs

It also like PWM rates of about 5KHz so is best driven with a hardware pwmgen

What existing hardware/daughtercards do you have? Probably the best solution is to get the PWM,DIR, and /ENA directly from your FPGA card or from a directly connected daughtercard.

I have 5i25, 2 of 7i85 and 2 of 7i84

. I also have a spare 5i25 available.

How many encoders/sserial interfaces do you need?

(you could probably steal a couple 7I85 sserial TX pins as PWM,DIR,ENA)

(with a 5I25 config with PWM gens on those pins)

another option is a 7I83 (though its overkill)

Thanks for the help.

I am going to go with a 7i83.

I have 3 extra encoder counters and 3 extra sserial interfaces available but I don't want to mess with a custom firmware config.
