ChibiOS Free Embedded RTOS

I've successfully implemented a USB-UART bridge using Serial-over-USB (SDU1) and Serial (SD1).

Now I want to implement CDC_SET_LINE_CODING. I understand that I can write my own sduRequestsHook to do this. But sduRequestsHook is called from ISR and I cannot call thread level function sdStop(&SD1) and sdStart(&SD1, &newconfig) from inside.
Is there anyway to do this? Or I need to operate registers directly?

Thanks

Hi,

You could wakeup a thread for that, using an event for example.

Good point anyway, it is a weakness.
