DE2 Expansion Header

I'm trying to interface to a servor motor using the

DE1 Board Altera/Terasic Expansion Header.

I placed the Vhdl Servo Driver Code for the UP1-Bot (from book "Rapid Prototyping of Digital Systems") into the cyclone 2C20F484C7 fpga and routed the LMotor & RMotor signals to output pins directly to the expansion header. I also routed the Vcc and Gnd from the x.gdf schematic to the expansion header. I am wondering if the series resistors in line with the expansion header pins is attenuating the PWM 20ms/2ms signals to the servos? Does Altera have any application notes in reference to a proper servo interface???
