USB as Device Driver

[kirantujare]

Hi,

I am using a customized board with MK50DX256.
I want to use processor expert in CodeWarrior to use it as a device driver. I want to be able to use the serial function in hyperterminal through USB. Is there a bean in processor expert that would help me achieve that? Also any sample project would help?

Hello Kiran,

You can use the component of  "USB_LDD".

After add this component , right click it , then select the  "help on component " , then click "Typical Usage",

there is USB demo :

Hope it helps

Hi Alice,

I am doing a project for USB CDC using this link https://centaurian.co.uk/2015/12/23/ksdk-usb-cdc-printf/
I got it working for my board. I want to type on hyper terminal and I am not being able to do that. How do I make scanf work for that? Please reply in your spare time.

Hey Alice,

I was using example project for MK53N512 from Freescale USB Stack v4.1.1 to port a project for MK50DX256CLK10. I wanted some help on porting a project. I tried it and ran into some errors. I wish you could help me resolve them? I have attached the screenshot below.

Hi ALice,
I installed USB Stack v4.1.1 NXP bare metal (no OS) USB Stack and imported USB_.PEupd components in the processor expert but I cannot view USB_AUDIO_CLASS.PEupd and USB_CDC_CLASS.PEupd because the processor expert filters these components. Is there a way to remove the filter. I have pointed out the place where it is filtered in the attached file

[Alice_Yang]

Hello Kiran,

1) You can disable the filtering :

2) If you use the PE component , there is demo code on the "help on component " i said above.

3) I see you use the chip of K53DN512 ,  you can also download the KSDK ,use the KDS IDE,

there are USB demo for TWR-K60D100, it is the same with mk53dn512 Chip .

You can refer to this thread to download and install KSDK v2.0 on KDSv3.2 :

Using Kinetis Design Studio v3.x with Kinetis SDK v2.0

when download KSDK, select the chip you used .

Hope it helps

Alice
