前言：定制网站使用的显示屏其实可以定制网站开发出许多定制网站有趣的小项目，比如：定制网站多功能菜单，小游戏等等。其中，STM32F1XX定制网站由于芯片的性能一般（定制网站计算量与内存），定制网站所以能够实现的小游戏不多，定制网站较为常见的：贪吃蛇，定制网站俄罗斯方块，定制网站飞机大战等。定制网站本文将给大家实现一款定制网站较为新颖的小游戏——定制网站谷歌小恐龙（Chrome Dino Game）。简单使用0.96寸OLED屏幕搭配STM32F1系列的MCU定制网站就可以实现，定制网站硬件要求很低。（定制网站本游戏代码基于HAL库实现，定制网站文末有代码开源）

实验硬件：STM32F103ZET6；0.96寸OLED；2个KEY按键

定制网站硬件实物图：

效果图：

引脚连接：

OLED模块：

VCC --> 3.3V

GND --> GND

SCL --> PB10

SDA --> PB11

KEY按键模块：

KEY0 --> PE3

KEY1 --> PE4

注意：定制网站这里按键直接采用了正定制网站点原子精英板上的固有按键，定制网站自己打板的话，定制网站视情况下而定。

一、谷歌小恐龙（Chrome Dino Game）简介

谷歌小恐龙（Chrome Dino Game）顾名思义是由Google公司首创出来的小游戏。其初始目的为在Google浏览器出现互联网信号丢失时，排解用户等待联网信号时的无聊难受。

这个游戏的最大优点是它可以在没有互联网的情况下玩。这是Chrome浏览器中一款原始的无止境跑步游戏。主角是一只可爱的霸王龙，它在古老的沙漠中小跑。当然，恐龙游戏有它的目的：避免仙人掌和翼手龙。虽然游戏看起来很简单，但并不需要很长时间就能变得很难，因为游戏的速度会随着你的进步而不断提高。

本文就以谷歌小恐龙（Chrome Dino Game）游戏为原型，使用STM32于0.96寸OLED屏幕上尽可能地复现了谷歌小恐龙游戏。

二、OLED简介

关于OLED的使用与原理不熟悉的笔者欢迎去笔者另一篇文章学习，由于篇幅问题，这里就不过多讲诉。

三、KEY按键

开发板上除了有经典的流水灯之外，还有一个必备的练习硬件--按键（key）。

正常地独立按键KEY其实使用很简单，就是基于GPIO引脚的读取操作。唯一需要注意的点：按键按下去之后到底时低电平还是高电平。

笔者这里直接使用了正点原子精英版STM32上的按键KEY，按键原理图如下：

考虑到本次小游戏只使用2个按键KEY，这里取KEY0和KEY1。KEY0和KEY1按下后为低电平有效。（这里读者朋友可以根据实际情况去设置）

四、CubeMX配置

1、RCC配置外部高速晶振（精度更高）——HSE；

2、SYS配置：Debug设置成Serial Wire（否则可能导致芯片自锁）；

3、I2C2配置：这里不直接使用CubeMX的I2C2，使用GPIO模拟（PB10：CLK；PB11：SDA）

4、KEY按键配置：PE3与PE4设置为端口输入（开发板原理图）

5、时钟树配置：

6、工程配置

五、代码讲解

5.1 OLED驱动代码

此部分OLED的基本驱动函数，笔者使用的是I2C驱动的0.96寸OLED屏幕。所以，首先需要使用GPIO模拟I2C通讯。随后，使用I2C通讯去驱动OLED。（此部分代码包含了屏幕驱动与基础显示，如果对OLED显示不太理解的朋友可以去看看上文提到的笔者的另一篇文章）

此部分函数主要是实现快速绘制出游戏所需要的模型组件，模型包括：游戏初始化封面，游戏结束封面，小恐龙（跳跃的小恐龙），沙漠地面，随机出现的仙人掌障碍物（1，2，3个），云朵等。

注意：此部分绘制的属于动态化图片绘制，所绘制的图片会自右向左移动。

关于游戏模型基础组件，采用Img2Lcd2.9软件对图片进行取模，注意考虑到0.96寸的OLED屏幕大小有限，取模图片尽可能小一点。

例子：

取模小恐龙模组：

Img2Lcd2.9软件如下操作取模：

其余，游戏图片模组依此法进行取模，注意图片取得的大小。

5.3 游戏运行代码

游戏运行代码，主要包含两个部分：（1）按键代码；（2）游戏运行判定代码

按键代码key：


int get_key_val()
{
	if(HAL_GPIO_ReadPin(GPIOE, GPIO_PIN_4)==0)
	{
		HAL_Delay(10);            //消抖
		if(HAL_GPIO_ReadPin(GPIOE, GPIO_PIN_4)==0)
		{
		return 2;
		}
	}
	if(HAL_GPIO_ReadPin(GPIOE, GPIO_PIN_3)==0)
	{
		HAL_Delay(10);            //消抖
		if(HAL_GPIO_ReadPin(GPIOE, GPIO_PIN_3)==0)
		{
		return 1;
		}
	}
	return 0;
}

游戏运行判定代码running：


		if (failed == 1)
		{
			OLED_DrawRestart();
 
			key_num = get_key_val();
			if (key_num == 2)
			{
				if(score > highest_score) highest_score = score;
				score = 0;
				failed = 0;
				height = 0;
				reset = 1;
				OLED_DrawDinoJump(reset);
				OLED_DrawCactusRandom(cactus_category, reset);
				OLED_Clear();
			}
			continue;
		}
 
 
		score ++;
		if (height <= 0) key_num = get_key_val();
 
		OLED_DrawGround();
		OLED_DrawCloud();
 
		if (height>0 || key_num == 1) height = OLED_DrawDinoJump(reset);
		else OLED_DrawDino();
 
		cactus_pos = OLED_DrawCactusRandom(cactus_category, reset);
		if(cactus_category == 0) cactus_length = 8;
		else if(cactus_category == 1) cactus_length = 16;
		else cactus_length = 24;
 
		if (cactus_pos + cactus_length < 0)
		{
		  cactus_category = rand()%4;
			OLED_DrawCactusRandom(cactus_category, 1);
		}
 
		if ((height < 16) && ( (cactus_pos>=16 && cactus_pos <=32) || (cactus_pos + cactus_length>=16 && cactus_pos + cactus_length <=32)))
		{
			failed = 1;
		}
 
		OLED_ShowString(35, 0, "HI:", 12);
		OLED_ShowNum(58, 0, highest_score, 5, 12);
		OLED_ShowNum(98, 0, score, 5, 12);
 
 
		reset = 0;
 
		cur_speed = score/20;
		if (cur_speed > 29) cur_speed = 29;
		HAL_Delay(30 - cur_speed);
//		HAL_Delay(500);
		key_num = 0;
    /* USER CODE BEGIN 3 */
  
  }

这里简单给大家说明一下，代码原理：根据按键的读取的数值去控制小恐龙的运动状态，同时，屏幕上不断移动和随机生成仙人掌障碍物，得分随着游戏进行增加。花一点时间去读一下程序，还是很好理解的。（为了复现出原版谷歌小恐龙随时间增加，速度越来越快的特性，这里根据用户得分情况，使用减小延迟函数时间去加快游戏速度提高难度）

六、游戏效果

笔者是一只手拍摄，一只手玩这个游戏，再加上KEY按键靠得太近，按得不方便，所以反复GG。（小声：好吧，笔者太菜！）实在话，感觉小恐龙跑得太快的话，可以把得分延迟函数基础数值加大一点。
