can tud_audio_fb_set() be called from inside tud_audio_feedback_interval_isr()?

[mastupristi]

I have this curiosity:
can tud_audio_fb_set() be called from inside an interrupt handler such as tud_audio_feedback_interval_isr()?
I think the question is legit, because calling tud_audio_fb_set() causes the use of FreeRTOS functions that should not be called from inside an interrupt.

You can even run the whole TUSB stack inside IRQ, it's what I does to ensure audio streaming has the highest priority.

But this usage doesn't support RTOS yet, so you need to set CFG_TUSB_OS = OPT_OS_NONE and take care of concurrency manually.

void USB1_IRQHandler(void)
{
  tud_int_handler(1);
  tud_task();
}
