7i92/G540/C10/THCAD

Hi all,

i have a similar question, as above. I want to connect a THCAD to my 7i92.
On the 7i92 i run 2 breakoutboards (see below) however i can't figure out what pins  i need to connect the thcad to.
How can i find where the encoder pins are connected to?

Thanks!

Unfortunately it would be pretty awkward with those breakouts as the inputs
are slow 12V signals. Even with level shifting I don't know if they could deal
with the ~8KHz signals from the THCAD using the highest divider ratio (128)

The breakout board inputs are activated by grounding so you could try adding
a NPN transistor/small MOSFET to do the level translation from the THCADs ~5V signals
to the 12V required but no guarantees...

A better solution might be to drive the appropriate 7I92 line directly (with maybe a 100 ohm
series resistor for safety)

should i get another bob? and if so what would you recommend?

A CNC4PC C10 (that the OP used) is probably a good choice as its an all 5V BOB.

Great!
just one last silly question: how can i find out to what pins the encoder connects?

i can't find anything about the physical pin numbers in the .ini or .HAL file?
i connected the stepper drivers to wahtever the BOB said and that worked but i feel that this is just luck...
where can i find this?

mesaflash --device 7i92 --addr [card_ip_address] --readhmid

will print the pinout of the currently loaded 7I92 firmware
