hc32l13x lcd分别点亮每个灯示例代码

以下是一个使用hc32l13x控制LCD分别点亮每个灯的示例代码：

#include "hc32l13x.h"

#define LCD_DATA_PORT   M4_PORT->P4OUT
#define LCD_CTRL_PORT   M4_PORT->P5OUT

#define LCD_RS_PIN      M4_PORT_Pin_5
#define LCD_RW_PIN      M4_PORT_Pin_6
#define LCD_EN_PIN      M4_PORT_Pin_7

#define LCD_DATA_PIN_4  M4_PORT_Pin_0
#define LCD_DATA_PIN_5  M4_PORT_Pin_1
#define LCD_DATA_PIN_6  M4_PORT_Pin_2
#define LCD_DATA_PIN_7  M4_PORT_Pin_3

void LCD_WriteCmd(uint8_t cmd)
{
    LCD_CTRL_PORT &= ~(LCD_RS_PIN | LCD_RW_PIN);
    LCD_DATA_PORT = cmd;
    LCD_CTRL_PORT |= LCD_EN_PIN;
    LCD_CTRL_PORT &= ~LCD_EN_PIN;
}

void LCD_WriteData(uint8_t data)
{
    LCD_CTRL_PORT |= LCD_RS_PIN;
    LCD_CTRL_PORT &= ~LCD_RW_PIN;
    LCD_DATA_PORT = data;
    LCD_CTRL_PORT |= LCD_EN_PIN;
    LCD_CTRL_PORT &= ~LCD_EN_PIN;
}

void LCD_Init(void)
{
    // Initialization sequence for HD44780 LCD controller
    LCD_WriteCmd(0x38);
    LCD_WriteCmd(0x0C);
    LCD_WriteCmd(0x06);
    LCD_WriteCmd(0x01);
}

int main(void)
{
    // Enable GPIO clock
    M4_PORT->PER |= (M4_PORT_Pin_0 | M4_PORT_Pin_1 | M4_PORT_Pin_2 | M4_PORT_Pin_3 | M4_PORT_Pin_5 | M4_PORT_Pin_6 | M4_PORT_Pin_7);
    M4_PORT->PCR[M4_PORT_Pin_0] |= (PORT_FUNC_GPIO | PORT_DIR_OUT);
    M4_PORT->PCR[M4_PORT_Pin_1] |= (PORT_FUNC_GPIO | PORT_DIR_OUT);
    M4_PORT->PCR[M4_PORT_Pin_2] |= (PORT_FUNC_GPIO | PORT_DIR_OUT);
    M4_PORT->PCR[M4_PORT_Pin_3] |= (PORT_FUNC_GPIO | PORT_DIR_OUT);
    M4_PORT->PCR[M4_PORT_Pin_5] |= (PORT_FUNC_GPIO | PORT_DIR_OUT);
    M4_PORT->PCR[M4_PORT_Pin_6] |= (PORT_FUNC_GPIO | PORT_DIR_OUT);
    M4_PORT->PCR[M4_PORT_Pin_7] |= (PORT_FUNC_GPIO | PORT_DIR_OUT);

    // Initialize LCD
    LCD_Init();

    // Turn on each light one by one
    for (uint8_t i = 0; i < 8; i++)
    {
        LCD_WriteCmd(0x80 + i);
        LCD_WriteData(1 << i);
    }

    while (1)
    {
        // Loop forever
    }
}

该示例代码使用了hc32l13x的GPIO模块来控制LCD的数据和控制线。LCD初始化后，使用`LCD_WriteCmd`和`LCD_WriteData`函数来向LCD发送命令和数据。通过循环来逐个点亮每个灯。
