7i43-4 firmware

hi
Is there anyone who could create a firmware for the mesa 7i43-400 card?

ciao

What firmware do you need?
 

if you remember, some time ago, I wanted to create a signal for an RC servo... and you advised me to use rcpwmgen; now that I understand how it works (but how fragmented is the information?) I need to insert it into the firmware of my card.
could you create a custom firmware for me? then I'll tell you which pins the function must be present on, if it's possible

Yes its possible, do you have the full pinout needed?


Its a bit tricky because EPP interfaced cards don't have the full HM2 64K
address space (only 32K) and since the RCPWM is recent and uses an
address above 32K, I need to use an alternate address below 32K.
This should be completely transparent as the FPGA specifies
each modules address's

if it's easier for you you could use ONESHOT (but I think the base is the usual rcpwmgen one)
the configuration I use is the SVST4_4 with
4 stepgens and 2 encoders
the stepgens are on connector 3 on pins 24-25 28-29 36-37 42-43
the encoders are on connector 4 on pins 0-1-2-3-4-5

if it were possible I would need 2 or 4 rcpwmgen outputs on connector 4 and any pin ranging from 16 to 23

I installed a 7i42 on connector 3, but it is so underneath other boards/components that it would be difficult for me to change the wiring
on connector 4 I installed a 7i37 which is much freer and more accessible

Its a bit tricky because EPP interfaced cards don't have the full HM2 64Kaddress space (only 32K)

I also have a 7i90 that I got a few years ago that I would like to use with a raspberry... would you advise me not to use it if I wanted to make a new cnc?

Firmware for a 7I43-400 with 4 encoders, 2 PWMgens, 4 Stepgens and 8 RCPWMgens
untested...

 

You can use the 7I90 with a RPI(3,4) using a SPI connection

thanks so much for the files
I copied the folder to /lib/firmware/hm2/ do I need to do anything else?
Could you explain to me how to transform your .vhd file into the .xml files that the 7i43 requires?

sorry... I understood everything... the .bit file is what I need and it works
thanks again for your help

HI
yesterday I had only added the parameter to the initialization of hm2 (rcpwmgen=2) and looked to see if it had created the pins for me with show_hal_configuration
today I had the time to try to see how the component works on a real rc servo... and nothing comes out of the physical pin, it always remains at a high level, I also looked at the signal with an oscilloscope... electrically the pin works , I tried to set it from the .hal configuration and it changes state normally...
I also noticed that the .rate pin is not recognized by linuxcnc and gives me an error on startup
Could it be that the 7i43 can't process this component?
