i am using usb to program stm32 for blink code i insert binary pc13 was working but when i was try to run dht22 it was fail to read the sensor why
The reason for the failure would probably be
a) a problem in your sketch (which you haven't shown us), or
b) a problem in your schematic (which you haven't shown us) or
c) a problem in your wiring (which you also haven't shown us).
No one here can read minds. We can only see what you show us.
I would urge you to read and follow the excellent advice to be found in How to get the best out of this forum.
