This one have the reverse pin. Its for a single motor I *
If you say it should work then im buying it:smile:

You must only left one pin unconnected, thats all. You can remove the not needed code if you like.
The second bridge is here at me, working good.

At the first test my arduino gets broken. So i orderd a new one and it's in delivery. So i startet to reading this post again searching for my mistake. There is something i don't understand:
"For the first run you should switch both power offsets to zero (2x right for each output) and the PWM frequency to 3kHz (round buttons top right)."

Where did i find these settings?

Open the arduino plugin (does work without a arduino connected).

But how it will have enough information from two potentiometers (two motors) + forward and reverse with only two pins?

have a look on this close up view of pins :



as described on ebay http://cgi.ebay.fr/ws/eBayISAPI.dll?Vie ... 1439.l2649

The motor is runnning : DIR = 1 PWM = PWM
understand set DIR pin to high and PWN pin with a value between 1 (slow) and 255 (fast)
Motor Reverse: DIR = 0 PWM = PWM
understand set DIR pin to low and PWN pin with a value between 1 (slow) and 255 (fast)
and the motor will go reverse

Parking brake: DIR = X PWM = 0
understand whatever DIR pin is set to
if PWN pin is null = 0 then motor is braked

i'm right ? thanks for any confirmation

[sirnoname]

yes

[RafBR]

yes

Ok I understand. So dont mater if the h-bridge have one or two dir pin per motor for the available firmware?

Edit: Sorry, too silly question after re-reading whole thread again
Regards!

Hi,
today i builded one test setup to test if everything works correctly. Im using wiper motors and an arduino nano with the H bridges on the first post, the 17$ ebay ones.
When i start converter and go into interface settings the pot is recognized correctly and i have setted up the min and max. position by hand. Now i power up the motors and enter a value in the set out box. My motor moves to tjis position and holds but makes a grinding noise all the time and both of the leds on h bridge for left and right are lighted. Did i have to change something in the code?

Make a screenshot of your XPID settings in X-Sim.
I think the power offset is set to non zero = always motor power for faster reactions.
