Hi guys, i've a problem with USART communication using interrupts.
Using only USART device, the communication works correctly.
When i try to using the usart device with some other timers interrupt routines with timers about 100 msec seems that these routines blocks the USART.

How can i handle the interrupt priority vector?

Now i use a global NVIC structure and set all the priority value to 0 but the USART priority is set to 4. But don't works.
