Posted on December 28, 2015 at 11:07Hello to all,
just to inform you about an inconsistency of HAL_GPIO_INIT:
I have a pin which triggers an EXT-Int and is also an input to the timer capture register.
With Standard Peripheral Library configuring EXT-Int and Alternate Function was separate. There was no conflict at all.
Now with in HAL_GPIO_INIT Alternate Function and EXT-Int config is combined.
And here comes the problem:
If you configure the alternate function first and thereafter the external interrupt feature,
the last call to HAL_GPIO_INIT sets the MODER register to input mode!!
So your previous alternate function setting in MODER is gone....
However if you configure the EXT-Int first and thereafter the alternate function everything is ok.
I hope this saves at least a little bit of time to the programmers who have to switch from peripheral lib to CUBE
best regards
Andy
