Posted on August 15, 2011 at 05:52Hi,
I am doing a very simple test, enable EXT11 interrupt. In the ISR, I toggle a GPIO pin. I connect the scope to both EXT11 line and the GPIO I am toggling in the ISR.
They somehow do not match. It seems ISR is skipping 2 beats out of 8 (at this in my test case).
Has anybody had a similar issue? What I could be doing wrong? The whole thing is so simple that it should just work, unless there is some major bug in interrupt handling part of STM32.
