STM32F103C8T6 pin multiplexing problem

[112233]

hello,STM32F103C8T6 enables SPI1, but does not use MISO pin (PA6), can this pin reuse other functions? For example, timer function.

Also, the PWM output can be observed in the software simulation, but there is no PWM output in the actual test. Is there something wrong with the hardware?

Please confirm, thank you!

No. Unlike other STM32, the 'F1 has a very inflexible GPIO scheme.

You still can use PA6 as GPIO Input or Output, but not for timer.
