5i25 + 7i85s +....

With STXO works.

I have flashed the 5i25 with mesaflash too.

Tomorow i will continue with the HAL file to set the pwmgen correctly.

Thank you for your support.

Hello again,

Im trying to make the HAL file to work.

I have wired the STX0 to ENABLE of SPIN1X and works nice.

I have wired TX7 to PWM and TX6 to DIR.

This is my lines of the HAL file:

setp hm2_5i25.0.gpio.001.is_output 1

net spindle-enable motion.spindle-on => hm2_5i25.0.gpio.001.out hm2_5i25.0.pwmgen.00.enable

net spindle-speed-cmd motion.spindle-speed-out => hm2_5i25.0.pwmgen.00.value

setp hm2_5i25.0.pwmgen.00.scale 17500

When i click in the clockwise button of linuxcnc, the SPIN1X lights the LED of ENABLE and SPEED.

When i click in the anti-clockwise button of linuxcnc, the SPIN1X just lights the ENABLE.

Can i use the TX6 for the direction?? My TX6 is always high no matter which button (anti or clockwise) i press.

Thank you.

Which GPIO do TX6, TX7 and STX0 correspond to?

Perhaps your pwmgen is not set to PWM / DIR but instead is in UP / DOWN mode?

With the 7i85ssp config TX7 is PWM and TX6 is direction

The one who is GPIO is STXO, is used as ENABLE for SPIN1X.

The other two are part of pwmgen, TX7 is PWM and TX6 is DIR.

I´ve set the output_type = 1, being PWM and DIR.

But the thing is that TX6 is always HIGH no matter which button (clock or anti) i press.

Can you check that the pwmgen sees a negative input value in the reverse direction?
