I read through the datasheet that was provided. In fact, as alec_t notes, that datasheet states "PPM," but I think what it means is the PWM that is used for model servos.
The datasheet goes on to state, "The PPM output of most RC receivers is compatible." I am not aware of any common receiver, much less most that output a PPM signal to servos. I think the author of that datasheet has confused the PPM modulation (PCM being another common mode) from the transmitter that the receiver receives with the decoded output from the receiver.
In short, connect a typical PWM servo tester to the esc, and I will bet it works. Most important, there are many examples of code in C for driving such servos. I believe that is worth a try for your project.
