对于使用51单片机控制OLED显示屏,我们通常会使用像SSD1306这样的图形显示模块,它有特定的驱动库支持。这里提供一个基于ATmega328P和SSD1306的基本示例代码片段,假设你已经包含了必要的库文件:
```c
#include <avr/io.h>
#include <Wire.h>
#include "SSD1306.h" // SSD1306 OLED库
#define OLED_I2C_ADDR 0x3C // SSD1306默认地址,根据实际连接修改
SSD1306 oled(SSD1306_I2C, SDA, SCL); // 初始化I2C OLED设备
void initOLED() {
oled.begin(); // 设置屏幕尺寸(例如128*64)并初始化
oled.clearDisplay();
}
void drawText(int x, int y, char *text) {
for (int i = 0; text[i] != '\0'; ++i) {
oled.setCursor(x, y);
oled.print(text[i]);
x += 1;
if (x > oled.width - 1) { // 每行结束后回车到下一行
x = 0;
y++;
}
}
}
int main(void) {
initOLED();
drawText(0, 0, "Hello, OLED!"); // 在左上角写入文本
oled.display(); // 显示内容
while (1); // 程序无限循环
}
