Thank you for reply!

I am starting with C2000 launchPad LAUNCHXL-F28069M, try to configure PWM. When I use analogFrequency(), it is black(not working). I checked the wiring_analog.c and found this function is empty. The problem now is I don't know how to write analogFrequency() by myself. Did someone already fulfill the function and would like to give some advice? Thanks.
