Has anyone combined FreeRTOS and USB ROM routines on an LPC11U2xx?

Hello, everyone!

We are starting the design of a new version of our product's firmware, in which we will combine our current USB ROM-based firmware with FreeRTOS. Our target architecture is the LPC11U2xx Cortex-M0 family, and we base our firmware on LPCOpen libraries.

Has anyone been successful in doing that? If so, could you share the main issues to take into consideration? Has it been easy/hard? Are there any pitfalls to avoid?

We are starting right now, and having some guidance would be greatly appreciated.

Thanks,

Julio

Hi,

I searched below demo for your reference:

GitHub - Protoneer/LPC11U14-FreeRTOS-with-Virtual-USB-Serial-and-LEDBlinky: This is example code of using an LPC11U14 wi…

And there with below discussion before about the similar application:

Wish it helps.

Have a great day,

Hi, Mike,

Thanks for the pointers, we'll take a look at them.

Just for the record, in case anyone browses at our question, we also found a good reference at the FreeRTOS site, in which they describe how to put together a USB interface with FreeRTOS and LPCOpen libraries. By following their advice, we were able to achieve our goals.

Regards,

Julio
