I am using a cRIO and have an NI9474 that I would like configure for Pulse-Width Modulation (PWM). I can configure the 9474 for PWM using the SCAN Interface but not when using the FPGA interface. When using the FPGA Interface the module installs as a boolean device and does not allow me to configure for PWM. Is it possible to configure the NI9474 foir PWM when using the FPGA Interface? I want to use the FPGA Interface because my update rate needs to be greater than 1 KHz. The SCAN Interface limits me to 500 Hz.

Hi shall12,
Yes it is possible to configure the 9474 for PWM using the FPGA interface. The tutorial below describes how to accomplish this:

Also, the following link includes some examples:
