Argon - PWM & Direction input

Argon / Mige 1KW - Upgrading from IONI

Can you please let me know if it’s possible to set up the Argon for a PWM input for PWM & direction (similar to IONI) so I can do forward (0-100% duty cycle + direction flag : 0% duty = zero speed) ?

Is this a firmware change, or something more major? I have a system designed primarily for the IONI, but I’m looking to expand it to the Argon for higher power (but using same +/- 0-100% duty PWM for control).

Many thanks Guys.
