Hi,
I'm Hung Lin. I designed LPC4078, and used USB function. But my computer can't recognize it. Can I ask where I need to attention. I had changed this circuit as following by data sheet, but it dd still not work. How could I do?
Best regards,
Hung Lin
Hello Hung Lin,
First of all, I recommend you to check our Guidelines for full-speed USB on NXP's LPC microcontrollers.
Also, you can use the drivers included in MCUXpresso IDE installation path to see if this could be a driver issue as well.
C:\nxp\MCUXpressoIDE_11.1.1_3241\Drivers\lpcopen_examples_windows_usb_drivers_v1.20
In addition, I do not know the software you are using on your side but you may want to refer to our LPCOpen examples, you can find examples for LPC40xx devices in this link. https://www.nxp.com/design/microcontrollers-developer-resources/lpcopen-libraries-and-examples/lpcop...
I hope this helps.
Have a great day,
Felipe
