帮我写出rtc时钟表盘代码

抱歉，我是一个语言模型AI，没有办法直接为您编写代码。不过，以下是一个使用Python语言绘制RTC时钟表盘的示例代码，供您参考：

import turtle
import math

# 设置窗口大小
turtle.setup(800, 800)
turtle.title("RTC时钟表盘")

# 绘制表盘外框
turtle.penup()
turtle.goto(0, -200)
turtle.pendown()
turtle.circle(200)

# 绘制小时刻度
for i in range(12):
    turtle.penup()
    turtle.goto(0, 170)
    turtle.right(i * 30)
    turtle.pendown()
    turtle.forward(20)
    turtle.penup()
    turtle.goto(0, 150)
    turtle.write(str(i+1), align="center", font=("Arial", 12, "normal"))
    turtle.goto(0, 0)

# 绘制分钟刻度
for i in range(60):
    turtle.penup()
    turtle.goto(0, 190)
    turtle.right(i * 6)
    turtle.pendown()
    if i % 5 == 0:
        turtle.forward(10)
    else:
        turtle.dot(2)
    turtle.goto(0, 0)

# 绘制时针、分针和秒针
hour_hand = turtle.Turtle()
minute_hand = turtle.Turtle()
second_hand = turtle.Turtle()

hour_hand.penup()
minute_hand.penup()
second_hand.penup()

hour_hand.goto(0, 0)
minute_hand.goto(0, 0)
second_hand.goto(0, 0)

hour_hand.right(90)
minute_hand.right(90)
second_hand.right(90)

hour_hand.pensize(5)
minute_hand.pensize(3)
second_hand.pensize(1)

while True:
    # 获取当前时间
    now = turtle.datetime.datetime.now()

    # 计算时针、分针和秒针的角度
    hour_angle = (now.hour % 12) * 30 + now.minute / 2
    minute_angle = now.minute * 6
    second_angle = now.second * 6

    # 旋转时针、分针和秒针
    hour_hand.setheading(hour_angle)
    minute_hand.setheading(minute_angle)
    second_hand.setheading(second_angle)

    # 绘制时针、分针和秒针
    hour_hand.pendown()
    hour_hand.forward(60)
    hour_hand.penup()

    minute_hand.pendown()
    minute_hand.forward(90)
    minute_hand.penup()

    second_hand.pendown()
    second_hand.forward(120)
    second_hand.penup()

    # 暂停1秒钟
    turtle.delay(1000)

    # 清除时针、分针和秒针
    hour_hand.clear()
    minute_hand.clear()
    second_hand.clear()

turtle.done()

该代码使用turtle库绘制RTC时钟表盘和时针、分针、秒针，并通过获取当前时间来控制时针、分针、秒针的旋转。您可以根据自己的需求进行修改和优化。
