I'm having trouble setting up the PWM component in PEx. I want to output a simple PWM waveform with a base frequency of about 25 kHz.
I added the PWM component to my project, and selected "FTM0_C1V" for the PWM device. But when I try to select the pin to route the output to, they are all prefixed with the symbol "[!]". There is no documentation what that means so I'm guessing that means that those pins are not available??? There is some text in red on that line. It says, "Peripheral-signal is not specified for the pin routing, Unassigned peripheral". I'm not sure what that means or how to fix it.
So, I just selected a pin, PTB1, and the error changed to "Peripheral-signal is not specified for the pin routing". This error is not documented, so I'm wondering how to fix it.
So, I opened the TimerUnit_LDD component that the PWM component references. The top two entries in the Component Inspector had an error, "Unassigned peripheral". I clicked on the second one, "Counter" and selected "FTM0_CNT". This caused the first line ("Module name") to be changed to "FTM0". I selected a random value for the Counter frequency and all the errors for TU1 went away, but this didn't help the errors in the PWM component.
When I tried to change the Period of the PWM component, the dialog box had an error: "Invalid component configuration: Property does not specify any peripheral for timing configuration". I'm puzzled as to what peripheral it's referring to. I specified the TU1 Timer and FTM0....
I also tried using the PinSettings component to reserve FTM0, channel 1 (Pin T7, PTB1), but that didn't change anything.

Can someone help?
Thanks.
