Is it possible to control DC motor from Odrive tool?

[Aviv_Harrari]

hi,
is it possible to control DC motor (at 1 of 3 states only - on/off/on-reverse ) from Odrive tool - without burning new software?
I have 1 BLDC in the product, using an Odrive to control it. I need to introduce a DC (brushed) motor to demo something.
is it possible to hack it by only using the stock Odrive-tool and Odrive firmware?

thanks,

Aviv

See:

Brushed Motor Control?

A simple way to hack it might be to connect to phase A and phase B, leave phase C disconnected. Then send voltage commands along v_alpha only, leaving v_beta = 0. Of course the proper way would be to dispense with the SVM all together. In this case, you may wish to use phase B and phase C (leaving phase A disconnected), since as mentioned this may have current measurement redundancy you could use (not required). To do the proper way, you need to send your own modulation timings. You may have s…

You may still need to hack the firmware to do this though, i’m not sure.

could I just send voltage commends directly to the respected wire (B and C for example)?

Yes, if you write a function to do that and add it to the interface yaml.
