MAX7219使用tweepy的Twitter流媒体

Question

我正在尝试使用 tweepy 和 Raspberry Pi 在 MAX7219 4 合 1 点矩阵上显示推特流。到目前为止，我已经能够：

• 在矩阵上打印消息
• 创建过滤包含特定字词的推文的主播。

但我不确定如何在一个脚本中统一所有内容。

这是我用于在矩阵中打印的代码：

#!/usr/bin/env python
# -*- coding: utf-8 -*-
import re
import time
import argparse
from luma.led_matrix.device import max7219
from luma.core.interface.serial import spi, noop
from luma.core.render import canvas
from luma.core.virtual import viewport
from luma.core.legacy import text, show_message
from luma.core.legacy.font import proportional, CP437_FONT, TINY_FONT, SINCLAIR_FONT, LCD_FONT
t_end = time.time() + 30
while time.time() < t_end:
def demo(n, block_orientation, rotate):
serial = spi(port=0, device=0, gpio=noop())
device = max7219(serial, width=8, height=32, block_orientation=block_orientation, rotate=rotate or 1)    
print("Matriz creada")
msg = "FUNDACION HORIZONTAL"
print("Mensaje: " + "'" + msg + "'" + " compartido")
show_message(device, msg, fill="white", font=proportional(CP437_FONT))
time.sleep(1)

if __name__ == "__main__":
parser = argparse.ArgumentParser(description='matrix_demo arguments',
formatter_class=argparse.ArgumentDefaultsHelpFormatter)
parser.add_argument('--cascaded', '-n', type=int, default=1, help='Number of cascaded MAX7219 LED matrices')
parser.add_argument('--block-orientation', type=int, default=0, choices=[0, 90, -90], help='Corrects block orientation when wired vertically')
parser.add_argument('--rotate', type=int, default=0, choices=[0, 1, 2, 3], help='Rotate display 0=0°, 1=90°, 2=180°, 3=270°')
args = parser.parse_args()
try:
demo(args.cascaded, args.block_orientation, args.rotate)
except KeyboardInterrupt:
pass

这是我用来获取流的那个：

from __future__ import absolute_import, print_function
from tweepy.streaming import StreamListener
from tweepy import OAuthHandler
from tweepy import Stream
consumer_key=""
consumer_secret=""
access_token=""
access_token_secret=""
class StdOutListener(StreamListener):
def on_status(self, status):
print(status.text)
return True
def on_error(self, status):
print(status)
if __name__ == '__main__':
l = StdOutListener()
auth = OAuthHandler(consumer_key, consumer_secret)
auth.set_access_token(access_token, access_token_secret)
stream = Stream(auth, l)
stream.filter(track=['#livinglab']

我尝试通过填充消息来填充状态：

#!/usr/bin/env python
# -*- coding: utf-8 -*-
from __future__ import absolute_import, print_function
import re
import time
import argparse
from tweepy.streaming import StreamListener
from tweepy import OAuthHandler
from tweepy import Stream
consumer_key=""
consumer_secret=""
access_token=""
access_token_secret=""
from luma.led_matrix.device import max7219
from luma.core.interface.serial import spi, noop
from luma.core.render import canvas
from luma.core.virtual import viewport
from luma.core.legacy import text, show_message
from luma.core.legacy.font import proportional, CP437_FONT, TINY_FONT, SINCLAIR_FONT, LCD_FONT
class StdOutListener(StreamListener):
def on_status(self, status):
print(status.text)
msg = status.text.encode('utf-8')
return True
def demo(n, block_orientation, rotate):
serial = spi(port=0, device=0, gpio=noop())
device = max7219(serial, width=8, height=32, block_orientation=block_orientation, rotate=rotate or 1)    
print("Matriz creada")        
print("Mensaje: " + "'" + msg + "'" + " compartido")
show_message(device, msg, fill="white", font=proportional(CP437_FONT))
time.sleep(1)
def on_error(self, status):
print(status)
if __name__ == "__main__":
l = StdOutListener()
auth = OAuthHandler(consumer_key, consumer_secret)
auth.set_access_token(access_token, access_token_secret)
stream = Stream(auth, l)
stream.filter(track=['#livinglab'])
parser = argparse.ArgumentParser(description='matrix_demo arguments',
formatter_class=argparse.ArgumentDefaultsHelpFormatter)
parser.add_argument('--cascaded', '-n', type=int, default=1, help='Number of cascaded MAX7219 LED matrices')
parser.add_argument('--block-orientation', type=int, default=0, choices=[0, 90, -90], help='Corrects block orientation when wired vertically')
parser.add_argument('--rotate', type=int, default=0, choices=[0, 1, 2, 3], help='Rotate display 0=0°, 1=90°, 2=180°, 3=270°')
args = parser.parse_args()
try:
demo(args.cascaded, args.block_orientation, args.rotate)
except KeyboardInterrupt:
pass

知道吗？

我更改了我的on_status函数，从矩阵中调用演示函数，它起作用了：

def on_status(self, status):
print(status.text)
def demo(n, block_orientation, rotate):
serial = spi(port=0, device=0, gpio=noop())
device = max7219(serial, width=8, height=32, block_orientation=block_orientation, rotate=rotate or 1)
print("Matriz creada")
msg = status.text
print("Mensaje: " + "'" + msg + "'" + "compartido")
show_message(device, msg, fill="white", font=proportional(CP437_FONT))
demo(1, 0, 0)
return True
def on_error(self, status):
print(status)
