MCUxpresso Ide configuration for USB CDC

raduansarif — Mon, 21 Mar 2022 10:21:22 GMT

Hello,

I want to run a USB CDC example for MKL27Z64LH4 in Windows 10. I debug the code with JLink EDU but I didn't get any output. I think I have to configure MUCxpresso Ide to run the code.

How do I need to configure the IDE? e.g. clocks, peripherals, and pins.

MKL27Z64LH4 datasheet says it supports USB FS 2.0 but I am using USB 3.0, is there any problem?

Thanks in advance. I will be really thankful if anyone helps me with this problem as it is part of my master's thesis.

What exactly does this part mean?:

"MKL27Z64LH4 datasheet says it supports USB FS 2.0 but I am using USB 3.0, is there any problem?"

If you are asking can up plug the 27Z into a blue USB 3.0 Type-A port, the answer is yes.
If you mean something else, the answer is no.

Take a look here:

It may be easier to get TinyUSB running, as there is a KL25 example. Difference to the KL27 is t mostly initialization.
