Posted on December 16, 2014 at 09:45Hello,
for low power purposes my application normally runs at MSI-128KHz. If USB cable is conencted I switch to HSE-32MHz in order to have USB working and I have to get back to low frequency when disconnecting.
Problem is that as soon as the frequency is set to low, I receive USB_LP_IRQHandler() interrupt that kill the main loop. How can I disable USB interrupt keeping it working again if cable is re-connected?
Kind regards
