That means you are still running the old mesaflash
Yup, fixed now.
Did you build the mesaflash source with "sudo make install" ?
yes
But apparently the setp for output-type takes a different syntax as
trying to set it to zero is a pin not found showstopper??? And I
can't find it in any similar name in halshow???
That should be
setp hm2_5i25.0.pwmgen.00.output-type N
From the bottom of my .ini file:
[AIR_0]
PWMGEN_S_FREQ = 4000
PWMGEN1_TYPE = 0
PWMGEN0_TYPE = 1
from the setp's in my .hal file:
setp hm2_5I25.0.pwmgen.01.output-type [AIR_0]PWMGEN1_TYPE
setp hm2_5i25.0.pwmgen.00.output-type [AIR_0]PWMGEN0_TYPE
There was a couple typu's above.
But that does not agree with the software version, logging this at
startup of linuxcnc:
hm2/hm2_5i25.0: invalid pwmgen output_type 0 requested
hm2/hm2_5i25.0: supported .output-type values are: 1 (PWM & Dir), 2 (Up &
Down), 3 (PDM & Dir), and 4 (Dir & PWM)
I can run on 2 or 3, ignoring the dir so thats not a real problem.
Getting the correct polarity, off=low, when the machine power is off
might be. OTOH they won't run long without a hot supply, which also goes
away when F2 is toggled off.
Thats correct, 0 is not a valid PWM type
To invert the output polarities, you would:
for PWM 0
setp hm2_5i25.0.pwmgen.00.out0.invert_output true
for PWM 1
setp hm2_5i25.0.pwmgen.01.out0.invert_output true
I'm about spent for the day, the years are tattling on me, so thank you
Peter.
Take care & stay well, both of you.
Cheers, Gene Heskett.
