Hi Peter,

I need custom firmware for my amazing 7i76EU with:

- 7i76 daughter for router 5 axes + 0-10V vfd (currently working with 7i76eu_7i76x1_7i85sx1d.bin)
- 7i85 (1 serial, 2 encoder, 4 stepgen) on P1 (currently working with 7i76eu_7i76x1_7i85sx1d.bin)  
- 1 or 2 PWM generator on P3 for 20kHz laser control and idealy the rest as I/O port

Can you create such firmware combining all these ? Do you need more info ?

Board IP: 192.168.1.121

Thanks!

I'm not clear on what daughter card
you have: 7I85 or 7I85S ?

I can make firmware for either.

I got the 7I85 ;)

But I had to buy the S version... My mistake

I'll be fine if the P3 with 1 or 2 pwm and all the others P3 ports as IO if possible ?

So 7I76EU firmware for a 7I85 on P2  and 2 PWMgens on P3 is what you want?

Firmware for a 7I76EU with a 7I85 on P2 and 2 PWMgens on P3

Note that since P3 pins are unbuffered/unprotected it's best to add
a say 100 to 220 Ohm series resistor to pins connected to the rest of the system
(or use a cheap parallel port breakout card)
