Wildfire STM32 motor series (1) Cubemx configuration GPIO

tip: The first project is the main file, and the subsequent functions are mainly to use Cubemx to generate code and then transplant it to the motor control project.

1 project establishment

You can directly browse the wildfire information, here is the configuration to match the hot sun board

1.1 Create a project as shown below

 

 1.2 GPIO port

The button (GPIO input press is high level) pin is

SW7/RESET

KEY1/SW2=PA0

KEY2/SW3=PG2

KEY3/SW3=PC13

KEY4/SW4=PG3

KEY5/SW5=PG4

The lamp (GPIO output active high) pin is

LED1=PA15

LED2=PE2

LED3=PG15

LED4=PB8

 Configure the GPIO one by one, press the button to select output, led to select input

Below, the LED needs to be changed (high-level push-pull pull-up high-speed mode)

 

1.3 Clock and other configurations 

 

 Configured here as a personal habit

 

 Click to generate code

2 Engineering Verification

Simply configure the emulator and try to see if it can be burned into it

 

3 function function added

1. Add a function to determine whether the button is pressed and turn on and off the LED light

2. The main function uses the button to light up the LED light to test the configuration and function

3. Finally tidy up the code

The specific code is as follows

//根据输入数字点亮对应LED灯
void LED_ON(unsigned char c)
{
	if(c==1)
	{
		HAL_GPIO_WritePin(LED_1_GPIO_Port, LED_1_Pin, GPIO_PIN_RESET);
	}
	if(c==2)
	{
		HAL_GPIO_WritePin(LED_2_GPIO_Port, LED_2_Pin, GPIO_PIN_RESET);
	}
	if(c==3)
	{
		HAL_GPIO_WritePin(LED_3_GPIO_Port, LED_3_Pin, GPIO_PIN_RESET);
	}
	if(c==4)
	{
		HAL_GPIO_WritePin(LED_4_GPIO_Port, LED_4_Pin, GPIO_PIN_RESET);
	}
}
//根据输入数字关闭对应LED灯
void LED_OFF(unsigned char c)
{
	if(c==1)
	{
		HAL_GPIO_WritePin(LED_1_GPIO_Port, LED_1_Pin, GPIO_PIN_SET);
	}
	if(c==2)
	{
		HAL_GPIO_WritePin(LED_2_GPIO_Port, LED_2_Pin, GPIO_PIN_SET);
	}
	if(c==3)
	{
		HAL_GPIO_WritePin(LED_3_GPIO_Port, LED_3_Pin, GPIO_PIN_SET);
	}
	if(c==4)
	{
		HAL_GPIO_WritePin(LED_4_GPIO_Port, LED_4_Pin, GPIO_PIN_SET);
	}
}
//按键检测
unsigned char Key_scan(void)
{
	unsigned char unKey_Val = 0;
	
	if(HAL_GPIO_ReadPin(GPIOA, GPIO_PIN_0)==GPIO_PIN_SET)
			unKey_Val = 1;
	if(HAL_GPIO_ReadPin(GPIOG, GPIO_PIN_2)==GPIO_PIN_SET)
			unKey_Val = 2;
	if(HAL_GPIO_ReadPin(GPIOC, GPIO_PIN_13)==GPIO_PIN_SET)
			unKey_Val = 3;	
	if(HAL_GPIO_ReadPin(GPIOG, GPIO_PIN_3)==GPIO_PIN_SET)
			unKey_Val = 4;
	
	return unKey_Val;
}

The main function test code is as follows
