Dear all

I configured PC.0 in STM32f103 as input in interrupt mode as rising edge. There's a pulse connected to PC.0. We need to STM32f103 reply to any rising edge by push the bus low.

When I want to detect rising edge, I should configure STM32f103 as interrupt input. But when I want to reply to this pulse I should configure the PC.0 as output. I want to know is it possible to change the pin mode during interrupt routine? how we can configure that?

I test some codes but the problem was when program enter interrupt routine, never  come back to main loop.

I'm waiting for your response.
