Control stepper motors with radio control

Hello everyone, I'm from Argentina, excuse my english

I'm doing a "slow car that carries some weight" which has two wheels to turn and traction back (and two free wheels forward) --- are two stepper motors nema17 high torque.
I try to handle it with my radio control station (PWM) and arduino.
ohhh I forgot, there are also two DRV8825 controllers to move the motors.

I just tried the Arduino-DRV8825 set and engines with a code and they work perfect. I also adjusted the current in the drivers.

I am finding it difficult to find a code that I can use with my radio and my engines to drive this micro car.

Is there any code already made for this? I understand that I would have to connect my pins according to the program ...... but programming I do not know anything! I will appreciate a lot of help ... it is sad to see the engines turned off

my stepper motor:

More information is required.
What transmitter and receiver are you using? (Make and model.)
What is the name and version number of the firmware on the transmitter?
Do you have two channels, one for each stepper motor/DRV8825?
It is not obvious to me that the DRV8825 would support a reverse function, does it?
Is reverse something you want to control?

Yes, motors sitting there do nothing is not a happy result, hopefully people here can help overcome this!
