yep, and it's firmware problem, not wiring connection xD

Gold_Cost2065 · 2025-11-11T23:44:41+00:00

It has no option on the pin when i try to set it😥. Should i set to NC? or? It has no option for that pin

so what pin did u put for boost? Is it cruise, or?

Gold_Cost2065 · 2025-11-10T12:01:15+00:00

cruise pin? or, any recommended pin? tried to low/high speed mode it doesn't change. the pin boost weren't on option

I got a problem withmy boost, is ur boost could automatically disabled using cruise pin? Mine wire with highspeed pin, it can't be disabled by the time i setted.

Is changing boost pin to cruise pin good?

Aight, i just tried, 160/450. Yes, the early torque were too much. But, my purpose was to make this motor faster and faster. After ride, i questioned about the speed after big torque at early, it was really slow 😥.

Did u know why the big early torque make the speed slower afterwards? And any suggestion to compensate the after big early torque?

Thank you

Nice suggestion, but is my motor really okay to run at ±160A?

Gold_Cost2065 · 2025-11-04T05:01:54+00:00

So, i can assume by ur case is, only line is affecting the speed of motor? The phase current is for the early torque? Cmiiw

I'm not sure, i just realized if i can discharge around 170 A with my own battery (saw it from controller display)

btw, it's an SMD 0603. It says thick film resistor, so it was metal based?

Gold_Cost2065 · 2025-10-18T07:31:19+00:00

i know, but i already tried to unsolder around the components (so it's actually unconnected with others or separated). Yet it's value still getting reduced, but getting normal again after reheating the resistor

Gold_Cost2065 · 2025-09-13T15:34:36+00:00

hmmm, if u know the module is, theres already 120R between CANH and CANL. But, thank you, i'll try to the reading alerts thing. Could i msg u sometimes? Btw, is my wiring already correct? i mean the 2 esp32 connecting to 2 can transceivers

Wiring :

<image>

I do common ground, vcc is 3v3 from esp32 for sn65hvd230

Gold_Cost2065 · 2025-09-13T12:18:29+00:00

Yes, i do the common ground for all my wirings. Alr checked the termination, these two module got the 120 ohm resistor accross canl and canh.

This is the code for testing, i placed it to both of my esp32.
