mesaboard 5i24 with 7i48 and 7i33 was created by mpvriens
Hello,
Have a mesa 5i24 card with board 7i48 working perfect now.
Would like to use the mesa 5i24card with 7i48 board and have flashed SV12IM_2x7i48.72.BIT software, but like to ad an other 7i33 board.
What software to use, or how to change the pin set for the 7i33
any suggestions?

It would be a lot easier to use a second 7i48, is that not an option?
There isn't a standard Mesa firmware that supports that combination as far as I know. It is actually possible that muxed encoders and ordinary encoder modules cannot be mixed in the firmware.
So, you will need a custom firmware, which is something that you can do yourself with some effort. I have made firmwares but I am not sure if my setup supports the 5i24 FPGA.

Using an other 7i48 could be an option, if there is no other solution, as i do have the 7i33 boards on stock.
I was looking at the firmware .xml files, and had the idea to changes the pins and functions there, only then there should
be a kind of translation from xml to .BIT file to flash it .
But this is just a guess, as i could't find any documentation around this.

Would 2 x 7i33 give you enough channels?Using an other 7i48 could be an option, if there is no other solution, as i do have the 7i33 boards on stock.
The xml files are only used by pncconf and are not part of the firmware building process. The actual pin assignments are controlled by .vhd files:I was looking at the firmware .xml files, and had the idea to changes the pins and functions there, only then there should

It is possible to use a 7I33 and a 7I48 together. Currently the hm2 driver cannot deal with
a combination of muxed and non-muxed encoders so what you do is use 8 muxed encoders
on the 7I33 (and ignore all the odd or even encoders)
so for example with a 7I48 first you would have
7I48:
enc0
enc1
enc2
enc3
enc4
enc5
7I33:
enc6
enc7 dummy copy of enc6
enc8
enc9 dummy copy of enc8
enc10
enc11 dummy copy of enc10
enc12
enc13 dummy copy of enc12
Not very elegant, but it works...

Hello
with a 6i24-25 and the combination 7i48 + 7i33 + 7i44
the encoders refuse to count?
Thank you for your attention

Your encoder (and PWM) numbering is not correct (they are overlapped)

Note that muxed encoders are numbered per pair, so your 14 (0x0E) encoders would be
listed in the pinout section as
7I48 0,1,2
7I33 3,4,5,6
listed in the pinout section as
7I48 0,1,2
7I33 3,4,5,6
