e-skateboard brakes

Trying to replicated https://endless-sphere.com/forums/viewtopic.php?f=35&t=74880 braking.

currently hacking:

run_reverse: rcall wait_for_low nFET_brake_on i_temp1 sync_on rcall wait_for_high nFET_brake_off i_temp1 rcall wait_for_low nFET_brake_on i_temp1 rcall wait_for_high nFET_brake_off i_temp1 sync_off rcall wait_for_low nFET_brake_on i_temp1 rcall wait_for_high nFET_brake_off i_temp1

.macro nFET_brake_on
    AnFET_on
    BnFET_on
    CnFET_on
.endmacro

.macro nFET_brake_off
    in  @0, AnFET_port
    .if (INIT_PB & ((AnFET_port == PORTB) << AnFET)) | (INIT_PC & ((AnFET_port == PORTC) << AnFET)) | (INIT_PD & ((AnFET_port == PORTD) << AnFET))
    cbr @0, (1<<AnFET)+(1<<BnFET)+(1<<CnFET)
    .else
    sbr @0, (1<<AnFET)+(1<<BnFET)+(1<<CnFET)
    .endif
    out AnFET_port, @0
.endmacro

This is as far as I have gotten any help would be very much appreciated!

Thanks I have read about VESC but my aim was to get working a cheap redbrick ESC I own. I have everything but the dynamic throttle controlled brakes working.

Did you made any progress? I am now dealing with the same thing :(, recently bought RED BRICK 100A and find out that it is braking too hard.
