Can i change 3,3 v Gpio output in stm32f1 to 5V ?
once the STM32 is supplied from 3V3, it will not generate bigger voltage on its GPIO ring.
However, pins marked as FT (5V-tolerant) may be configured as open-drain and, if you use external pull up resistor to 5V rail, you can switch between 5V and zero. This solution has one drawback, the log. 1 output impedance is determined by the resistor size and GPIO current capability. Further the speed of toggling is reduced.
Hello mahmoud boroumand,
you cannot set output to 5V directly from STM32 using push-pull option.
Do you have any idea about that?
