我需要用单片机并使用micropython实现俄罗斯方块小游戏的python代码

好的，下面是一个基于micropython的俄罗斯方块游戏代码示例：

import random
from machine import Pin
from time import sleep

# 定义游戏区域的大小
WIDTH = 10
HEIGHT = 20

# 定义方块的形状
SHAPES = [
    [(0, 0), (1, 0), (0, 1), (1, 1)],  # 正方形
    [(0, 0), (1, 0), (2, 0), (3, 0)],  # 横条
    [(0, 0), (1, 0), (2, 0), (2, 1)],  # L 形
    [(0, 0), (1, 0), (2, 0), (0, 1)],  # 反 L 形
    [(1, 0), (2, 0), (0, 1), (1, 1)],  # Z 形
    [(0, 0), (1, 0), (1, 1), (2, 1)],  # 反 Z 形
    [(0, 0), (1, 0), (2, 0), (1, 1)],  # T 形
]

# 初始化游戏区域
board = [[0 for x in range(WIDTH)] for y in range(HEIGHT)]

# 定义方块的初始位置
shape = random.choice(SHAPES)
x = WIDTH // 2 - 1
y = 0

# 定义 LED 灯组的引脚
LED_PINS = [Pin(pin, Pin.OUT) for pin in [0, 1, 2, 3, 4, 5, 6, 7]]

# 定义按键的引脚
BTN_LEFT = Pin(8, Pin.IN, Pin.PULL_UP)
BTN_RIGHT = Pin(9, Pin.IN, Pin.PULL_UP)
BTN_ROTATE = Pin(10, Pin.IN, Pin.PULL_UP)
BTN_DOWN = Pin(11, Pin.IN, Pin.PULL_UP)

# 定义按键的检测函数
def is_button_pressed(button):
    return not button.value()

# 定义 LED 灯组输出函数
def set_leds(bits):
    for i, pin in enumerate(LED_PINS):
        pin.value((bits >> i) & 1)

# 定义游戏结束函数
def game_over():
    set_leds(0)
    while True:
        pass

# 定义方块下落函数
def drop_shape():
    global x, y, shape
    y += 1
    if check_collision(x, y, shape):
        for block in shape:
            board[y - block[1]][x + block[0]] = 1
        remove_lines()
        y = 0
        x = WIDTH // 2 - 1
        shape = random.choice(SHAPES)
        if check_collision(x, y, shape):
            game_over()

# 定义方块旋转函数
def rotate_shape():
    global shape
    new_shape = []
    for block in shape:
        new_block = (block[1], -block[0])
        new_shape.append(new_block)
    if not check_collision(x, y, new_shape):
        shape = new_shape

# 定义方块移动函数
def move_shape(dx):
    global x
    x += dx
    if check_collision(x, y, shape):
        x -= dx

# 定义检测碰撞函数
def check_collision(x, y, shape):
    for block in shape:
        if (
            x + block[0] < 0 or
            x + block[0] >= WIDTH or
            y + block[1] >= HEIGHT or
            board[y + block[1]][x + block[0]]
        ):
            return True
    return False

# 定义消除行函数
def remove_lines():
    global board
    new_board = []
    num_removed = 0
    for row in board:
        if all(row):
            num_removed += 1
        else:
            new_board.append(row)
    new_board = [[0 for x in range(WIDTH)]] * num_removed + new_board
    board = new_board

# 主循环
while True:
    # 检测按键
    if is_button_pressed(BTN_LEFT):
        move_shape(-1)
    if is_button_pressed(BTN_RIGHT):
        move_shape(1)
    if is_button_pressed(BTN_ROTATE):
        rotate_shape()
    if is_button_pressed(BTN_DOWN):
        drop_shape()

    # 更新 LED 灯组
    bits = sum(board[y][x] << i for i, x in enumerate(range(WIDTH)))
    bits |= sum(shape[y][x] << i for i, (x, y) in enumerate(shape))
    set_leds(bits)

    # 等待一段时间后继续下落
    sleep(0.5)
    drop_shape()

需要注意的是，这份示例代码使用了 LED 灯组来模拟游戏区域，如果你想在实际的单片机上运行，需要针对具体的硬件进行适当的修改。
