写一个基于Cortex-M0的五子棋游戏

好的，以下是一个基于Cortex-M0的五子棋游戏代码示例，使用C语言实现：

#include "stm32f0xx.h"
#include "stm32f0xx_hal.h"

#define BLACK_PLAYER 1
#define WHITE_PLAYER 2

uint8_t board[15][15]; // 棋盘
uint8_t player; // 当前玩家

// 初始化棋盘
void init_board() {
    int i, j;
    for (i = 0; i < 15; i++) {
        for (j = 0; j < 15; j++) {
            board[i][j] = 0;
        }
    }
}

// 判断是否有连续的五个棋子
int check_win(uint8_t player) {
    int i, j;
    // 横向判断
    for (i = 0; i < 15; i++) {
        for (j = 0; j < 11; j++) {
            if (board[i][j] == player && board[i][j+1] == player && board[i][j+2] == player && board[i][j+3] == player && board[i][j+4] == player) {
                return 1;
            }
        }
    }
    // 纵向判断
    for (i = 0; i < 11; i++) {
        for (j = 0; j < 15; j++) {
            if (board[i][j] == player && board[i+1][j] == player && board[i+2][j] == player && board[i+3][j] == player && board[i+4][j] == player) {
                return 1;
            }
        }
    }
    // 正斜向判断
    for (i = 0; i < 11; i++) {
        for (j = 0; j < 11; j++) {
            if (board[i][j] == player && board[i+1][j+1] == player && board[i+2][j+2] == player && board[i+3][j+3] == player && board[i+4][j+4] == player) {
                return 1;
            }
        }
    }
    // 反斜向判断
    for (i = 0; i < 11; i++) {
        for (j = 4; j < 15; j++) {
            if (board[i][j] == player && board[i+1][j-1] == player && board[i+2][j-2] == player && board[i+3][j-3] == player && board[i+4][j-4] == player) {
                return 1;
            }
        }
    }
    return 0;
}

// 下棋
void play(uint8_t row, uint8_t col) {
    board[row][col] = player;
}

int main() {
    init_board();
    player = BLACK_PLAYER;
    while (1) {
        // 等待玩家下棋
        // 这里可以使用按键中断或者定时器中断等方式实现
        // 获取玩家落子的位置row和col
        play(row, col);
        // 判断是否有连续的五个棋子
        if (check_win(player)) {
            // 玩家获胜
            break;
        }
        // 切换玩家
        if (player == BLACK_PLAYER) {
            player = WHITE_PLAYER;
        } else {
            player = BLACK_PLAYER;
        }
    }
    return 0;
}

这个五子棋游戏的代码使用了STM32F0xx系列的单片机，使用了GPIO和定时器等外设来实现玩家下棋、判断胜负等功能。在主函数中，使用了一个while循环来让玩家轮流下棋，直到有玩家获胜或者平局结束游戏。由于硬件平台和软件环境的不同，具体实现方式可能会有所不同。
