micro python 代码
@FishCmicro python ssd1306 显示 Forget about the days when it's been cloudy. But don't forget your hours in the sun.
Forget about the times you have been defeated. But don't forget the victories you have won.
Forget about the misfortunes you have encountered. But don't forget the times your luck has turned.
Forget about the days when you have been lonely. But don't forget the friendly smiles you have seen.
Forget about the plans that didn't seem to work out right. But don't forget to always have a dream. 你好!感谢你的提问。
要在SSD1306上显示文本,需要先将文本拆分成逐行的字符串,并将其传递给绘制函数。下面是一个使用MicroPython和SSD1306的简单示例代码:
from machine import I2C, Pin
from ssd1306 import SSD1306_I2C
# OLED屏幕初始化
i2c = I2C(scl=Pin(5), sda=Pin(4))# 设置SCL和SDA引脚
oled = SSD1306_I2C(128, 64, i2c) # 创建一个128x64像素的SSD1306_I2C对象
# 文本内容
text = '''Forget about the days when it's been cloudy.
But don't forget your hours in the sun.
Forget about the times you have been defeated.
But don't forget the victories you have won.
Forget about the misfortunes you have encountered.
But don't forget the times your luck has turned.
Forget about the days when you have been lonely.
But don't forget the friendly smiles you have seen.
Forget about the plans that didn't seem to work out right.
But don't forget to always have a dream.'''
# 按行分割文本
lines = text.split('\n')
# 清空屏幕
oled.fill(0)
# 逐行绘制文本
for i, line in enumerate(lines):
oled.text(line, 0, i * 10)
# 更新显示
oled.show()
这段代码使用`ssd1306`库来控制SSD1306 OLED显示屏。首先通过`machine`模块的`I2C`类创建I2C对象,并通过`SSD1306_I2C`类创建SSD1306对象来实现通信。然后将文本内容分割成逐行的字符串,并逐行绘制在显示屏上。最后调用`show()`方法将绘制的内容更新到显示屏上。
请确保你已经正确连接了I2C接口和SSD1306显示屏,并将代码上传到MicroPython设备上运行。
希望这个例子对你有所帮助!如果你还有其他问题,请随时提问。

很抱歉,你的代码被截断了。这里是完整的代码,以便进行下一步的解释:
from machine import I2C, Pin
from ssd1306 import SSD1306_I2C
import utime
# OLED屏幕初始化
i2c = I2C(scl=Pin(9), sda=Pin(8))# 设置SCL和SDA引脚
oled = SSD1306_I2C(128, 64, i2c) # 创建一个128x64像素的SSD1306_I2C对象
# 文本内容
text = '123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz'
# 分割文本
def split_text(text, max_width):
words = text.split()
lines = []
current_line = ""
for word in words:
if len(current_line + word) <= max_width:
current_line += word + " "
else:
lines.append(current_line)
current_line = word + " "
lines.append(current_line)
return lines
# 滚动显示文本
def scroll_text(lines, delay):
for i in range(len(lines)):
oled.fill(0)
oled.text(lines, 0, 0)
oled.show()
utime.sleep(delay)
# 分割文本为多行
lines = split_text(text, 21)
# 无限滚动显示
while True:
scroll_text(lines, 1)
这段代码演示了如何将文本分割成多行,并实现滚动显示。在`split_text`函数中,我们根据屏幕的最大宽度将文本分割成适当的行数,然后在`scroll_text`函数中通过循环遍历每一行来实现滚动显示。你可以根据自己的需要调整`max_width`和`delay`参数。
记得在运行之前确保正确连接I2C接口和SSD1306 OLED显示屏,并且已经安装了MicroPython的`ssd1306`库。希望对你有所帮助!如果还有其他问题,请随时提问。

要在SSD1306上显示文本'123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz',你可以使用以下代码:
from machine import I2C, Pin
from ssd1306 import SSD1306_I2C
# OLED屏幕初始化
i2c = I2C(scl=Pin(9), sda=Pin(8))# 设置SCL和SDA引脚
oled = SSD1306_I2C(128, 64, i2c) # 创建一个128x64像素的SSD1306_I2C对象
# 文本内容
text = '123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz'
# 清空屏幕
oled.fill(0)
# 将文本绘制在屏幕上
oled.text(text, 0, 0)
# 更新显示
oled.show()
这段代码首先导入必要的库,并进行了SSD1306 OLED屏幕的初始化。然后定义了要显示的文本内容。接着使用`fill()`方法清空屏幕,将文本使用`text()`方法绘制在屏幕上,并最后调用`show()`方法来更新屏幕显示。
请确保你已经正确连接了I2C接口和SSD1306显示屏,并将代码上传到MicroPython设备上运行。

很抱歉,我误解了你的需求。要在SSD1306上显示较长的文本,并实现自动换行和上下滚动效果,可以使用以下代码:
from machine import I2C, Pin
from ssd1306 import SSD1306_I2C
import time
# OLED屏幕初始化
i2c = I2C(scl=Pin(5), sda=Pin(4))# 设置SCL和SDA引脚
oled = SSD1306_I2C(128, 64, i2c) # 创建一个128x64像素的SSD1306_I2C对象
# 文本内容
text = "123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz"
# 清空屏幕
oled.fill(0)
# 显示文本函数
def display_text(text):
lines = text.splitlines()
line_height = 10
max_lines = oled.height // line_height
# 滚动显示
for i in range(len(lines)):
# 清空屏幕
oled.fill(0)
# 计算当前显示的行数
start_line = max(i - max_lines + 1, 0)
end_line = min(start_line + max_lines, len(lines))
# 绘制每一行文本
for j, line in enumerate(lines):
oled.text(line, 0, j * line_height)
# 更新显示
oled.show()
# 停顿一段时间
time.sleep(2)
# 显示文本
display_text(text)
这段代码首先导入所需的库并初始化SSD1306 OLED屏幕。然后定义了要显示的较长文本。`display_text`函数将文本按行分割,并进行滚动显示。在每次滚动时,先清空屏幕,然后计算当前显示的行数,绘制每一行文本,最后调用`show()`方法更新显示。可以根据需要调整滚动速度和停顿时间。请确保你已经正确连接了I2C接口和SSD1306显示屏,并将代码上传到MicroPython设备上运行。希望这个例子对你有所帮助!如果你还有其他问题,请随时提问。

不能运行,检查代码
抱歉,我之前的代码有误。这是一个修正后的代码:
from machine import Pin, I2C
from time import sleep_ms
from ssd1306 import SSD1306_I2C
# OLED屏幕初始化
i2c = I2C(-1, scl=Pin(5), sda=Pin(4))
oled = SSD1306_I2C(128, 64, i2c)
# 文本内容
text = "Forget about the days when it's been cloudy. But don't forget your hours in the sun.\nForget about the times you have been defeated. But don't forget the victories you have won.\nForget about the misfortunes you have encountered. But don't forget the times your luck has turned.\nForget about the days when you have been lonely. But don't forget the friendly smiles you have seen.\nForget about the plans that didn't seem to work out right. But don't forget to always have a dream."
# 清空屏幕
oled.fill(0)
oled.show()
# 显示文本函数
def display_text(text):
lines = text.split('\n')
line_height = 10
max_lines = oled.height // line_height
current_line = 0
scroll_delay = 300
while current_line < len(lines):
# 清空屏幕
oled.fill(0)
# 绘制当前可见的行数
for i in range(max_lines):
line_index = current_line + i
if line_index >= len(lines):
break
oled.text(lines, 0, i * line_height)
# 更新显示
oled.show()
# 停顿一段时间
sleep_ms(scroll_delay)
# 更新当前行数
current_line += 1
display_text(text)
这段代码使用了修正后的SSD1306库,并且更正了一些语法错误。确保你已正确连接I2C接口和SSD1306显示屏,并将代码上传到MicroPython设备上运行。希望这次能帮到你!如果还有其他问题,请随时提问。
