/* Capture error */
And I add the LED toggler as following in the handler:
I use oscilloscope to test, it would work only for serval time and stoped. On the other hand, I use USART3 to print the test information on PC, it would work continuously, but the frequency became 78Hz instead of 1KHz. Could anyone can tell me what is the problem? Appreciate.
