Help with scrolling 2 lines of text with runtext.py or other *.py #1087
Comments
|
Not clear what you mean, but do you want two different lines shown on the panel ? |
|
I am a systems/network administrator. Yes i would like to scroll 2 different lines of text simultaneously.
Can you explain about the "canvas"? I am only lightly versed in python,near zero in C++. I truly appreciate all of your coding and help to everyone on the forum.
If I stick with runtext.py, can you point me where to change the code.
#!/usr/bin/env python
# Display a runtext with double-buffering.
from samplebase import SampleBase
from rgbmatrix import graphics
import time
class RunText(SampleBase):
def __init__(self, *args, **kwargs):
super(RunText, self).__init__(*args, **kwargs)
self.parser.add_argument("-t", "--text", help="The text to scroll on the RGB LED panel", default="Hello world!")
def run(self):
offscreen_canvas = self.matrix.CreateFrameCanvas()
font = graphics.Font()
font.LoadFont("../../../fonts/7x13.bdf")
textColor = graphics.Color(255, 255, 0)
pos = offscreen_canvas.width
my_text = self.args.text
while True:
offscreen_canvas.Clear()
len = graphics.DrawText(offscreen_canvas, font, pos, 10, textColor, my_text)
pos -= 1
if (pos + len < 0):
pos = offscreen_canvas.width
time.sleep(0.05)
offscreen_canvas = self.matrix.SwapOnVSync(offscreen_canvas)
# Main function
if __name__ == "__main__":
run_text = RunText()
if (not run_text.process()):
run_text.print_help()

Of course - just modify the code to do that. You have the power of Python
or C++ at your hands, you can do anything you want with the canvas the LED
matrix provides.

I also have a similar requirement. Please provide if a solution exists! I am using c-code to make program for running two lines simultaneously, and for that i will have to run 2 for loops simultaneously inside main() function, is it possible? i think for that i will have to create a thread and in that thread the "canvas" will not be recognized, the "canvas" is only accessible in main() function isn't it? Please guide me in the right direction, Thank you! |

I will have to look over my notes and see how i finally got that to work. I
will get back to you shortly.

Thank you very much, i will be waiting... |

With script & python i am :
1 taking temperature readings from a database
2 combining all the information into 1 line
3 adjusting color of led text based on temp or humidity
4 creating a ppm
5 displaying ppm
Here my information Dump:

# Edit this file to introduce tasks to be run by cron.
#
# Each task to run has to be defined through a single line
# indicating with different fields when the task will be run
# and what command to run for the task
#
# To define the time you can provide concrete values for
# minute (m), hour (h), day of month (dom), month (mon),
# and day of week (dow) or use '*' in these fields (for 'any').
#
# Notice that tasks will be started based on the cron's system
# daemon's notion of time and timezones.
#
# Output of the crontab jobs (including errors) is sent through
# email to the user the crontab file belongs to (unless redirected).

I have read through all the pertinent info from adafruit and rpi-rgb-led-matrix. Sorry if this is a repeated question.
Is it done with multiple lines? like this:
self.parser.add_argument("-t", "--text", help="The text to scroll on the RGB LED panel", default="ZZZZZZ")
self.parser.add_argument("-t", "--text", help="The text to scroll on the RGB LED panel", default="XXXXXX")
Thanks in advance.
The text was updated successfully, but these errors were encountered:
