Can i use this hbridge for 2DOF Desk-racer?

I currently have bought two wiper motors anda Arduino with the following hbridge.
Link to Bridge:

I hope I can use this bridge. Do i Need a Special Arduino-Code for this hbridge?
I hope you can help.
regards,
Martin

A might but might require a change to the code, mmmmm 2 possible codes to check -

And think @RacingMat code could be a possibility.

Taken from their Manual:
 Rotate forward: EN = 1, RPWM = PWM, LPWM = 1, DIS = float (Here ‘1’means High, i.e.5V.)
 Rotate reverse: EN = 1, RPWM = 1, LPWM = PWM, DIS = float
 Stop and brake: EN = 1, RPWM = 1, LPWM = 1, DIS = float
 Stop but not brake: EN = 0, RPWM = 1, LPWM = 1, DIS = float (Here ‘0’means High, i.e.0V.)
 Prohibit the use: EN = X, RPWM = X, LPWM = X, DIS = 1 (Here ‘X’ means any status)

So maybe a slight customizing of code this could be used.
Like the 100amp peak possible could be a strong driver, looks a lot like the old tronic H bridge, lol.

Hi eaorobbie,
thanks.
Can you please explain to me what does EN and dis mean
how can i handle 2 pwm Pins?

THX,
martin

EN is the engage pin, if this is high - 1 - (5v) the H bridge is active and will supply power to motors when set low - 0 - (GND) the power is disrupted and the motors wont run.
Reading the manual Dis , Im not sure as no explanation given the only thing it says it to connect nothing to it, as in no wire connection.

Ok to go forwards we need to set:
EN = high(5v)
RPWM = PWM , this will range from 5v - 0v depending on the speed required, this pulses.
LPWM = PWM set to high 255 so it gives a steady 5v's
DIS = no wire connected to it.

Now to reverse we just set the RPWM = PWM set to high and on LPWM sets the speed with a PWM signal.

This is just a theory needs to be tested.
Another way tried is to wire a card in between like this :




This would be my preferred method.

Hi
Thanks for help. That cleared Dome things. So i have to find out how to connect to arduino. At the Moment i did Not get the board. So i Test it when i got it.
Thanks

I agree with you, it could be easily modified the way you described to Martin.Berger

Martin this will be your first exercise to learn Arduino

Hi Racing mat
I ll try
By the Way Thanks for your Tutorial.

Thanks! I hope to see your sim shaking you soon!

At the moment i m just learning and searching parts.
I think it will last till autumn i can build something.

A couple of alternate ways of using these H-Bridges with existing Arduino controlles:

1. Use the H-Bridge EN pin as the PWM input and use the PWM inputs as the Direction pins. Sounds odd but this drives the H-Bridge in drive/coast mode which is generally fine for motion sims as they are always in motion.

Arduino DIR1 -> H-Bridge LPWM
Arduino DIR2 -> H-Bridge RPWM
Arduino PWM -> H-Bridge EN

2. Use the SMC3 Arduino software in MODE2 - its already configured for this type of H-Bridge (Refer to the doco for connection setup details) This will drive te H-Bridge in drive/brake mode.

when an ard and h-brdige and wipers do this, then I will be impressed
