51驱动ST7735

根据提供的引用内容，可以了解到ST7735S是一种TFT液晶屏幕驱动芯片，而引用中提到的1.44寸TFT彩屏使用的就是ST7735S芯片。同时，引用中还提到了使用增强型51单片机STC12系列的MCU来驱动该屏幕。

因此，驱动ST7735S芯片的步骤如下：
1. 确定使用的MCU型号，例如STC12系列。
2. 根据ST7735S的引脚说明，连接MCU和液晶屏幕的SPI接口。
3. 编写程序控制MCU向ST7735S发送命令和数据，以控制液晶屏幕的显示。

以下是一个简单的示例代码，使用STC12C5A60S2作为MCU，驱动ST7735S芯片的1.44寸TFT彩屏：

#include <reg52.h>

sbit SDA = P1^0; // SPI数据线
sbit SCK = P1^1; // SPI时钟线
sbit CS = P1^2; // 片选信号线

void delay(unsigned int t) // 延时函数
{
    unsigned int i, j;
    for (i = 0; i < t; i++)
        for (j = 0; j < 125; j++);
}

void write_cmd(unsigned char cmd) // 向ST7735S发送命令
{
    CS = 0; // 片选信号线拉低
    SDA = 0; // 数据线拉低，表示发送命令
    SCK = 0; // 时钟线拉低
    SCK = 1; // 时钟线拉高
    SDA = cmd; // 发送命令
    SCK = 0; // 时钟线拉低
    CS = 1; // 片选信号线拉高
}

void write_data(unsigned char dat) // 向ST7735S发送数据
{
    CS = 0; // 片选信号线拉低
    SDA = 1; // 数据线拉高，表示发送数据
    SCK = 0; // 时钟线拉低
    SCK = 1; // 时钟线拉高
    SDA = dat; // 发送数据
    SCK = 0; // 时钟线拉低
    CS = 1; // 片选信号线拉高
}
