Servo RC to L298 Dual H-Bridge

Hi

looking for some code for Arduino (Mini is best) which will cover conversion between servo RC signal to L298 dual hbridge so I can use L298 on each of 6 motors on my new (Wild Thumper like) rover.

Do somebody know about something before I spend time with developing it ?

I do not understand your question because the L298 dual hbridge already has PWM inputs that you can connect directly to your RC receiver or your autopilot PWM ouputs. What are you trying to do ?
Here you can find some instructions :
