driver BTS7960 with arduino uno

[lispe]

Hello Arduinos,

I'm quiete new to arduino and I'm working with it to get some of my artpieces into motion.
Now, I'm stuck because I've got a new driver "BTS7960" for a larger motor and I've no clue how to connect it.
There's some info on the net, but unfortunately only for complex functions and what i need is very basic, maybe somebody can help?

I' like the wiper motor to move only in one direction, and code a (eg. PMWA) stop-go- rhythm. No turning directions or increasing speed.
Does anybody know how to connect them and what the code must look like then? :o
I really appreciate any suggestions. Any questions please let me know.
Greets from Berlin,
Lisa

You haven't included any information on your driver board - the chip part number isn't enough!

hey Mark
yes you're right. sorry and thanks for replying.
i attached to images. I think the sketch I found there might work.
It is quiet a simple setup that i think I can try out. and then see it it works with my standard code ?

const int DIRA = 12;
const int PWMA = 3;
const int BRAKEA = 9;

void setup() {
digitalWrite(DIRA, 0);
pinMode(DIRA, OUTPUT);
digitalWrite(BRAKEA, 0);
pinMode(BRAKEA, OUTPUT);
digitalWrite(PWMA, 0);
pinMode(PWMA, OUTPUT);
}

// the loop function runs over and over again forever
void loop() {

digitalWrite(PWMA, HIGH);
delay(15000);
digitalWrite(PWMA, LOW);
delay(6000);

The BTS7960 is a half-H-bridge chip. It takes an input (which is the PWM input as marked on the module)
and an enable input. There's also an analog current sense output.

So for H-bridge operation you need to have both enables high, and either PWM the Lpwm or Rprm for
controlling each direction. Setting the rpms both low will be a brake mode, there's no separate
brake pin.

With the enables low the motor will be undriven and will coast to a stop.

By pwm'ing the enable pin instead of the PWM pin you can probably do slow decay-mode

Hey Mark,
yes. exactly- I connected everything and my code didnt work. (:
But what you're writing I understand. i'll go from there and try again.Thanks a lot

I tried something very simple, but it's not doing nothing.
Any ideas?

int RPWM=5;
int LPWM=6;
// timer 0
int L_EN=7;
int R_EN=8;

void setup() {
Serial.begin (9600);
digitalWrite(5,HIGH);
digitalWrite(6,HIGH);
analogWrite(7,255);
delay(2000);
analogWrite(7,0);

digitalWrite(5,LOW);
digitalWrite(6,LOW);
digitalWrite(7,HIGH);
digitalWrite(8,HIGH);
}

Problem solved.
That code is actually working (:
Thanks for all the help

Ah good.

What is the code of the driver? We are also using this driver but got no idea how to start it in arduino. I search the net but has only basic functions. What we want in our code is for the motor to forward, backward, stop. Thanks.
