stm32驱动1.44tftlcd显示屏代码如何编写

驱动1.44寸TFT LCD显示屏需要考虑以下几个方面：

1. 硬件连接：需要将LCD与STM32芯片通过SPI或者8位数据总线进行连接，并且需要进行相应的引脚配置。

2. 控制器型号：需要确定LCD的控制器型号，以便编写相应的驱动程序。常见的控制器型号有ST7735、ILI9163C等。

3. 显示模式：需要确定LCD的显示模式，包括全屏刷新模式、局部刷新模式、点阵模式等。

4. 图像数据格式：LCD显示图像的数据格式有RGB565、RGB888、ARGB8888等多种格式，需要根据LCD的要求进行选择。

下面是一个简单的驱动程序示例，以ST7735为例：

#include "stm32f10x.h"
#include "TFTLCD.h"

// GPIO初始化函数，根据实际情况进行修改
void GPIO_Configuration(void)
{
    GPIO_InitTypeDef GPIO_InitStructure;
    RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOA, ENABLE);

    GPIO_InitStructure.GPIO_Pin = GPIO_Pin_5 | GPIO_Pin_7 | GPIO_Pin_6 | GPIO_Pin_4;
    GPIO_InitStructure.GPIO_Mode = GPIO_Mode_Out_PP;
    GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz;
    GPIO_Init(GPIOA, &GPIO_InitStructure);
}

// SPI初始化函数，根据实际情况进行修改
void SPI_Configuration(void)
{
    SPI_InitTypeDef SPI_InitStructure;
    RCC_APB2PeriphClockCmd(RCC_APB2Periph_SPI1, ENABLE);

    SPI_InitStructure.SPI_Direction = SPI_Direction_2Lines_FullDuplex;
    SPI_InitStructure.SPI_Mode = SPI_Mode_Master;
    SPI_InitStructure.SPI_DataSize = SPI_DataSize_8b;
    SPI_InitStructure.SPI_CPOL = SPI_CPOL_Low;
    SPI_InitStructure.SPI_CPHA = SPI_CPHA_1Edge;
    SPI_InitStructure.SPI_NSS = SPI_NSS_Soft;
    SPI_InitStructure.SPI_BaudRatePrescaler = SPI_BaudRatePrescaler_4;
    SPI_InitStructure.SPI_FirstBit = SPI_FirstBit_MSB;
    SPI_InitStructure.SPI_CRCPolynomial = 7;
    SPI_Init(SPI1, &SPI_InitStructure);
    SPI_Cmd(SPI1, ENABLE);
}

// 发送SPI数据
void SPI_WriteData(uint8_t data)
{
    while (SPI_I2S_GetFlagStatus(SPI1, SPI_I2S_FLAG_TXE) == RESET);
    SPI_I2S_SendData(SPI1, data);
    while (SPI_I2S_GetFlagStatus(SPI1, SPI_I2S_FLAG_RXNE) == RESET);
    SPI_I2S_ReceiveData(SPI1);
}

// 写命令到LCD
void WriteCommand(uint8_t cmd)
{
    TFTLCD_DC_LOW;

    WriteData(x >> 8);

int main(void)

以上代码仅供参考，实际使用时需要根据LCD的具体型号和要求进行修改。
