TTL (PWM) Laser head and Mesa 7i76

Sorry, the P2 wanted to say, I got confused, P3 (the DB25) I have it busy with the 7i76.
I have asked if the pins are the same to prepare the wire.

On P2, HDR Pin 1 connects to DB25 Pin 1, but the other pins are
not in order because of the way DB25 and HDR26 pins are numbered.
You don't need a special cable however just a flat cable with IDC
connectors (one HDR26 , one DB25) on each end.
(Mesa can supply these)

Ok, I'll wait to do it then with the pins you tell me based on the custom firmware.

Hi PCW, is there news of the custom firmware?

Here is a 5i25 config with PWM on P2 (it also adds 2 more step/dir outputs)

 

Very grateful PCW!!!
I understand that the pinout of the Chinese BB is like the one it has.
I see that in the zip comes a .vhd file, what is it for?
The .bit I imagine is to flash the 5i25 again like I did when I bought it.

Thank you very much, really, how much I want to try it
