USB Custom class for RT106x

carstengroen — Tue, 01 Jan 2019 15:31:11 GMT

Hello,

I need to make support for some PC tools we are using for an existing product (LPC2458/LPC1788/LPC54608). On this we are using a custom USB class (using 2 bulk endpoints transferring data from device to PC and 2 bulk endpoints transferring data from PC to the device).
I can't find any examples on custom classes in the RT10xx SDK's, there are a lot of the usual CDC, HID etc etc, but these are tightly "mangled" in with the USB library and it seems like a daunting task to take this apart to make a custom class driver (LOTS of #define and undocumented stuff going on).

This thread explains what I'm trying to accomplish, the thread is from when I did the porting to LPC5460x devices: https://community.nxp.com/thread/447669

Basically what I'm after is something along the lines of this...

Are there any examples "out there" for doing this, or am I totally on my own ??

Hi Carsten Groen,

Thank you for your interest in NXP Semiconductor products and for the opportunity to serve you.
I'd highly recommend you to create a custom USB demo by referring to the attachment.

Have a great day,
TIC

Thanks jeremyzhou,

I will have a look at these. I guess this means that there are no examples around for a custom class then

Have anyone here done something along the lines of a Bulk/Custom USB class for the RT105x/6x processors ?

Could really use some help here.....

Hi Carsten.

I'm in the same predicament as you. I need to implement the USBTMC class on the RT105x. No solution yet.

Thanks Richard,

I find it strange that there is not a single example for Custom USB class in all the wonderful examples that comes with the SDK :smileysad:, such a pity
