Mesa 7i43-U-4 with 7i33 + 7i37 was created by Falmeida
Hello, This is my first post here. My name is Fernando and write from Brazil.
I'm trying to set my Board 7i43 to control a Discovery 308: 3 analogical servos, 3 encoders, 1 stepper motor for the 4th axis. I will also need GPIO 7i37.
I do not have the firmware for this application. How can I get?

You can convert the stepgen PWM and encoder pins to GPIO by disabling some of the instances.
So I think you should be able to use the SVST firmware for your card, but only enable one step-generator to use the other pins on the 7i37 as GPIO

Yes, the standard SVST4_4 config should work for this set of daughtercards
Note that step rate will be limited by the 7I37

Thank you for the tips.
I uploaded the firmware SVST4_4 and seems to work.
I did the test probe encoders and manual turning the servo axis, I can see the signal change from false to true normally.
I tried to enable the servo and jog +10V can see this value on test probe (PC screen) but can not measure this value in corresponding analog port (7i33 board).
what am I doing wrong?

I tested my 7i33 board. Is ok! The problem is my SGDL Yaskawa driver wiring.
