[ST NUCLEO-U5A5ZJ-Q development board review] 1 Unboxing and powering on gpio operation
The packaging is still so beautiful, and the board is still so charming, haha.
The development of stm32 based on HAL library is the most convenient and is also recommended by st.
The same is true for stm32U5A5.
The following is a review of the GPIO of ST NUCLEO-U5A5ZJ-Q
1. Download the NUCLEO-U5A5ZJ-Q User Manual UM2861, which contains all the instructions for the board.
2. Open stm32cubeide and create a project based on the NUCLEO-U5A5ZJ-Q board
3. Refer to the gpio part of the board. The main purpose here is to light up the LED. There are ready-made led_red, led_green, and led_blue on the upper panel as shown in the figure
4. Add the corresponding code to light up the LEDs as shown in the figure:
5. The code is as follows:
