lpc2387 usb not working with freertos

Posted by Pravin Saini on September 13, 2013

I have been trying to implement virtual com port using lpc2387. I started with lpc code bunlde for keil .It works fine there.
But,when I try to do the same with Free rtos had no success.I found that my usb isr is not getting called. I have tried writing ISR handlers as per the demo code but no success.

Thanks .

...in which case you may find the USB stack is the same one use as in this project. If so you can use it as a reference for your project as, although it is running on an LPC chip, it is a Cortex-M chip rather than an ARM7.

Hope that helps.

You can convert the Cortex-M version to your chip, find one on the Internet, get one from NXP, .... or purchase a commercial USB stack (in which case you would require OpenRTOS rather than FreeRTOS).
