Modification of a file in the GD32F3x0 firmware library [Copy link]

Download the GD32F3x0__Flrmware_Library_V1.0.0 firmware library and find that: 1. The macro definitions of the three LEDs do not correspond to the hardware GPIO port of the development board; 2. The macro definition of button B3 does not correspond to the GPIO port; As a result, the LED cannot light up and button B3 is invalid. As shown in the figure below, LED4, LED5, and LED6 on the development board are connected to PB10, PB8, and PB9 respectively. Button B3 is connected to PB7 But the LED defined in gd32f3x0_eval.h is as follows:

1. #define LED1_PIN GPIO_PIN_10 #define LED1_GPIO_PORT GPIOC #define LED1_GPIO_CLK RCU_GPIOC #define LED2_PIN GPIO_PIN_11 #define LED2_GPIO_PORT GPIOC #define LED2_GPIO_CLK RCU_GPIOC #define LED3_PIN GPIO_PIN_12 #define LED3_GPIO_PORT GPIOC #define LED3_GPIO_CLK RCU_GPIOC #define LED4_PIN GPIO_PIN_2 #define LED4_GPIO_PORT GPIOC #define LED4_GPIO_CLK RCU_GPIOC The connection for button B3 is defined in PF7 #define USER_KEY_PIN GPIO_PIN_7 #define USER_KEY_GPIO_PORT GPIOF #define USER_KEY_GPIO_CLK RCU_GPIOF #define USER_KEY_EXTI_LINE EXTI_7 #define USER_KEY_EXTI_PORT_SOURCE EXTI_SOURCE_GPIOF #define USER_KEY_EXTI_PIN_SOURCE EXTI_SOURCE_PIN7 #define USER_KEY_EXTI_IRQn EXTI4_15_IRQn It is necessary to modify this to suit the board: [code]typedef enum { LED4 = 0, LED5 = 1, LED6 = 2, }led_typedef_enum;

1. #define LED4_PIN GPIO_PIN_10 #define LED4_GPIO_PORT GPIOB #define LED4_GPIO_CLK RCU_GPIOB #define LED5_PIN GPIO_PIN_8 #define LED5_GPIO_PORT GPIOB #define LED5_GPIO_CLK RCU_GPIOB #define LED6_PIN GPIO_PIN_9 #define LED6_GPIO_PORT GPIOB #define LED6_GPIO_CLK RCU_GPIOB #define USER_KEY_PIN GPIO_PIN_7 #define USER_KEY_GPIO_PORT GPIOB #define USER_KEY_GPIO_CLK RCU_GPIOB #define USER_KEY_EXTI_LINE EXTI_7 #define USER_KEY_EXTI_PORT_SOURCE EXTI_SOURCE_GPIOB #define USER_KEY_EXTI_PIN_SOURCE EXTI_SOURCE_PIN7 #define USER_KEY_EXTI_IRQn EXTI4_15_IRQn

In this way, the three LEDs and button b3 can be used normally.

This needs to be learned, maybe it will be useful
