5i25 + 7i85s +....

I have already done that. In fact in the HAL configurator i see these PINs High (yellow):

hm2_5i25.0.gpio.002.out

hm2_5i25.0.gpio.002.is_output

But the PIN 13 of TB1 of the 7i85s continues low ( 0 V.)

Thank you.

try setting the out pin to 0

I change the state from high to low and continues 0 V. From low to high and continues 0 V.

The Pin 14 ( non-TX7 ) is always 5 V.

When i set num_stepgens=4, the PIN13 is always 5 V. So i guess the PIN isnt damaged, but there is something that blocks me to control it.

Thank you.

Very strange, maybe something wrong in the hal file

Ok, tomorrow i will try with STX0, the outoput of SERIAL of the 7i85s. Is this PIN suitable for my needs??

Another question, when i will install the 5i25_7i85sspx2i.bit, will i be able to use TX7 for ENABLE and TX6 for PWM, or TX7 wont be able to do gpio??

Thank you!!

Just tried this here:
LinuxCNC 2.7.7, Debian Wheezy
5I25 --> P3 --> 7I85S
5i25_7i85sx2.bit config, 3 stepgens enabled

setp hm2_5i25.0.gpio.002.is_output true

setp hm2_5i25.0.gpio.002.out true
setp hm2_5i25.0.gpio.002.out false

toggle 7I85S TB1 pins 13/14

setp hm2_5i25.0.gpio.003.is_output true

setp hm2_5i25.0.gpio.003.out true
setp hm2_5i25.0.gpio.003.out false

toggle 7I85S TB1 pins 11/12
