A121 Integration using STM32CubeIDE
The “LD2 [green Led]“ on the Nucleo board shares functionality with “SPI1_CLK“. Before we add SPI functionality we
need to remove the “LD2 [green Led]“ configuration from PA5. The pin configuration is removed by doing a left mouse
click on PA5 / “LD2 [green Led]“ and then selecting “Reset_State“.
Figure 6: Remove LD2 pin
The “B1 [Blue PushButton]“ on the Nucleo board is not used on our examples and can be removed. The pin configuration
is removed by doing a left mouse click on PC13 / “B1 [Blue PushButton]“ and then selecting “Reset_State“.
