Its STM32F302R8T6, so I guess it does not have OTG.
Just realized one of the files I'm converting basically is
"usb_cdcacm/cdcacm.c" (from examples) with added stuff:
nvic_enable_irq(NVIC_OTG_FS_IRQ); and then:
void otg_fs_isr(void) { (this is interrupt handler, right?)
usbd_poll(usbd_dev);
}
Can you please help me, how could this be done in F3?
