   What kind of motors are you using?  What kind of H-bridge.  Your 
motor and H-bridge determine what the frequency is that you can use. 
For instance, cheapie Mabuchi motors like those used in toys and some 
gearboxes can't deal well with higher than 500 Hz.  The L293 H-bridge 
can't deal with a PWM frequency higher than about 1-2KHz (I blew the top 
off the chip when I accidentally used 19KHz on one!)

We need more details.

   If you don't want to write in assembly, and don't have money for a 
compiler then you can use avr-gcc, which runs on Mac, Linux and Windows 
and gives a higher level C environment.
