Hello,
What I want to do is using a gpio(GIOB0) pin as the external Interrupt
source,and other gpio pin(GIOB1) is triggered Interrupt by the GIOB0 high
level.And I tried many times to work out it, the problem is still there. I do
not know how to use the external input high level to trigger GIOB1, and the
setting of HAL.
I will be appreciate it if you can give me some answers,thanks.
