基于 STM32F412RE 的 Flappy bird 游戏机实现

两年前博主还没有毕业，正值疫情期间，在家闲的慌，就利用这段时间做了一个游戏机。采用锂电池供电，屏幕是1.54的ST7789，单片机采用STM32F412RE，那时后芯片还没有开始涨价，在淘宝只要12元就可以买到一片，那叫一个爽啊。256K flash ，256k sram，直接通过DMA-SPI实现整屏刷新，速度非常快，刷屏可以到50帧以上。下面附上效果视频

Flappy bird 游戏机效果

这套设备带有wm8978，sd卡和一个耳机接口是支持音频输出的，可以移植NES模拟器到上面运行 256k的 sram ，足够动态加载大多数游戏了。

Flappy bird 按键检测实现

按键检测部分在rtthread的一个任务中进行扫描，没有加消抖（懒得加了，几乎没有影响），源码如下：

#include "drv_key.h"__IO uint8_t KEY_NUM;//键值rt_thread_t key_tid; //任务句柄
void key_thread_entry(void *parameter);
int bsp_key_init(void)
{rt_pin_mode(KEY_UP_PIN, PIN_MODE_INPUT_PULLUP); rt_pin_mode(KEY_DOWN_PIN, PIN_MODE_INPUT_PULLUP);
//  rt_pin_mode(KEY_LEFT_PIN, PIN_MODE_INPUT_PULLUP);
//  rt_pin_mode(KEY_RIGHT_PIN, PIN_MODE_INPUT_PULLUP);rt_pin_mode(KEY_A_PIN, PIN_MODE_INPUT_PULLUP);rt_pin_mode(KEY_B_PIN, PIN_MODE_INPUT_PULLUP);
//  rt_pin_mode(KEY_C_PIN, PIN_MODE_INPUT_PULLUP);
//  rt_pin_mode(KEY_D_PIN, PIN_MODE_INPUT_PULLUP);key_tid=rt_thread_create("key_thread",key_thread_entry, RT_NULL,256,20, 4);if (key_tid != RT_NULL)rt_thread_startup(key_tid);//启动return 0;
}
void key_thread_entry(void *parameter)
{uint8_t _key_num;while(1){_key_num=0;_key_num|=((!rt_pin_read(KEY_UP_PIN))<<0);_key_num|=((!rt_pin_read(KEY_DOWN_PIN))<<1);
//      _key_num|=((!rt_pin_read(KEY_LEFT_PIN))<<2);
//      _key_num|=((!rt_pin_read(KEY_RIGHT_PIN))<<3);_key_num|=((!rt_pin_read(KEY_A_PIN))<<4);_key_num|=((!rt_pin_read(KEY_B_PIN))<<5);
//      _key_num|=((!rt_pin_read(KEY_C_PIN))<<6);
//      _key_num|=((!rt_pin_read(KEY_D_PIN))<<7);KEY_NUM=_key_num;rt_thread_mdelay(10);}
}INIT_DEVICE_EXPORT(bsp_key_init);

Flappy bird 随机数实现

随机数的实现采用的是硬件随机数，通过ST的RNG外设实现，随机数用来设置柱子的高度。

#include "drv_rng.h"RNG_HandleTypeDef hrng;//初始化RNG
int bsp_rng_init(void)
{hrng.Instance=RNG;if (HAL_RNG_Init(&hrng) != HAL_OK){return 1;//随机数产生器工作不正常}else return 0;
}//生成[min,max]范围的随机数
int rng_get_random_range(int min,int max)
{ return HAL_RNG_GetRandomNumber(&hrng)%(max-min+1) +min;
}INIT_DEVICE_EXPORT(bsp_rng_init);

Flappy bird 屏幕驱动实现

屏幕刷新使用 SPI-DMA 半字单次传输，速度非常快，在sram里开辟一个显存，不断的更新显存上的内容，这里使用单次传输，为什么不使用连续传输呢，因为没有双BUFF，你在写缓存的时候，DMA正好在刷你这一块内存，显示会不正常。

#include "drv_st7789.h"SPI_HandleTypeDef hspi1;

Flappy bird 游戏核心实现

首先要想显示出图像，需要图像数据，如果直接使用16位色BMP图片，那对内存消耗是很大的，不适合在单片机上使用，使用这里图片使用一种讨巧的方式实现，这样的处理方式极大减低了系统资源的使用。逻辑部分有碰撞检测，模式切换，位置计数，背景循环等，不做赘述，代码如下：
