Ⅳ STM32f407VET6 GIO 5 configurations

GPIO, which is a general-purpose I/O (input/output) port, is a pin that can be controlled by STM32. The GPIO pins of the STM32 chip are connected to external devices, which can realize the functions of communicating with the outside, controlling the external hardware, or collecting the data of the external hardware

STM32F407 has 7 groups of IO. They are GPIOA~GPIOG respectively, each group of IO has 16 IO ports, a total of 112 IO ports are usually called PAx, PBx, PCx, PDx, PEx, PFx, PGx, where x is 0-15. And the F4 series is based on the Cortex-M4 core.

Multiplexing of GPIO:

STM32F4 has many built-in peripherals, and the external pins of these peripherals are shared with GPIO. That is to say, a pin can have many functions, but it is an IO port by default. If you want to use a GPIO built-in peripheral function pin, you need GPIO multiplexing. When this GPIO is used as a built-in peripheral, It's called reuse. For example, a serial port is a GPIO multiplexed as a serial port.
