Request for firmware bitfile for Mesa 7i90HD + 7i85S (3 axes, encoders, PWM)

Hello,I have a Mesa 7i90HD connected via LPT and a Mesa 7i85S daughter card.I need a firmware for this combination with the following requirements: 3 step/dir generators (for 3 axes) 3 encoder channels (for linear encoders) 1 PWM output (for VFD spindle control) some GPIO for external control panel (buttons, signals)  I could not find a ready 7i90_7i85s.bit file on the Mesa website.Could someone please share a suitable bitfile or point me where to download it? Thank you in advance! Best regards,Aleksandr. 

Sorry, I didn’t quite understand what you mean by "without double posting". Could you please explain?

I understand, thank you! The duplication was unintentional. My apologies

Note that this is not a standard configuration as the 7I90 is a 50 pin connector FPGA card
and the 7I85S is s 25 pin FPGA card daughtercard. I pinned this out so a flat cable adapter
should be relatively simple (look at the included VHD source file for the pinout)

 

This has 3 stepgens and 1 PWMgen, 4 encoders and a sserial port
(on the 7I85S) 
 

Thanks a lot for the explanation! I will try this solution.

Note that the pins listed in the source file comments are DB25 pins

so

7I90  P4.1  --> DB25.1
7I90  P4.3  --> DB25.14
7I90  P4.5  --> DB25.2

etc

Thanks for the firmware file! When I try to flash it with mesaflash, I get the error Invalid bitfile header. It looks like this is a raw Xilinx ISE/Vivado .bit file. Could you please provide the firmware in the proper format for mesaflash (with the MESA header, or as a .bin file for the 7i90)?

 

Oops sorry, haste makes waste...
