Twitter #hashtag to scroll pHAT

hi Phil, many thanks for your input.
it can be asynchronous! but that’s set to false at the moment, http://docs.tweepy.org/en/v3.4.0/streaming_how_to.html as per sandys tutorial.
your FIFO suggestion looks ideal, this is just what i think it needs! i will take a look into implementing this soon but i’m afraid my time over the next couple of weeks is taken up designing various print works.

theres some strange quirks with the program which seem to freeze the system/scroller momentarily but now with the HD supported at least its heading in the right direction :)

thanks again for your input!

hi phil. i’ve managed to get the tweets going into the fifo queue now, many thanks for the tips!

also made a mainloop but i cant seem to get it to scroll though, any ideas? :)

#!/usr/bin/env python

import sys
import time
import tweepy
import scrollphathd
import Queue
from scrollphathd.fonts import font5x7smoothed

scrollphathd.clear()

#make FIFO queue
q = Queue.Queue()

#define main loop to fetch formatted tweet from queue
def mainloop():
    while not q.empty():
        status = q.get()
        scrollphathd.write_string(status,font=font5x7smoothed, brightness=0.1)            
        status_length = scrollphathd.write_string(status, x=0, y=0,font=font5x7smoothed, brightness=0.1)
        #print(status)
        print status
        #print 'status length --->',status_length
        while status_length > 0:
            #print 'status length',status_length
            #print 'buffer_len',scrollphathd.write_string(status, x=0, y=0,font=font5x7smoothed, brightness=0.1)
            #scrollphathd.flip(x=True)
            scrollphathd.rotate(degrees=180)                    
            scrollphathd.show()
            scrollphathd.scroll(1)
            status_length -= 1

ok here’s the latest code, saving and reading from the fifo queue and also scrolling ok now.

we be scrollin, scrollin, scrollin…

        status_length = scrollphathd.write_string(status, x=0, y=0,font=font5x7smoothed, brightness=0.1)
        #print(status)
        #print ("<<<<<< Scrolling tweet", status)
        time.sleep(0.25)
        #print 'status length --->',status_length

That’s a really nice, and well architected (in my humble opinion anyway) example. Are you up for submitting it in a PR to the Scroll pHAT HD GitHub repo?

How do you find font5x7smoothed? I never used it in an example since I thought it looked terrible, but it might fare better when scrolling.

Mr-G · April 24, 2017, 9:01pm

hi phil thanks, sure thing! the smoothed font is ok scrolling but the normal one is clearer for most uses imo… i was just trying it out really!
ill submit it as soon as i work out how to do that! :)

mypifi · April 30, 2017, 4:32pm

Brilliant will have to try it later. Well done :)

Mr-G · May 1, 2017, 10:00am

hey phil. unsure if it did it right but I’ve made a github repo with this project and did a pull request? can you check?

gadgetoid · May 3, 2017, 9:58pm

@Mr-G I can’t see an incoming PR for it? Did I (or someone else) merge it already?

Mr-G · May 3, 2017, 11:34pm

ok forked the pimoroni scroll-phat-hd repo then added my
hashtagtoscrollphathd.py file to examples. unsure if this is correct and i
also need to add some comments :)

MrHohenheim · July 8, 2017, 7:05pm

Hi, i used this code and still the same problem with scrollhathd examples twitterhashtag

if i tweet #bot_multi i see only 2 :: nothing more

Bugman_140 · July 8, 2017, 8:22pm

Yea I have exactly the same issue. I was starting to think it was just me

MrHohenheim · July 8, 2017, 8:49pm

i dont found any solution…

Bugman_140 · July 8, 2017, 8:57pm

same here, I have been trying all sorts
checking my keys and Tokens, different keywords, checking for possible case sensitive issues. but nothing has worked.

I ultimately want to change the code to scroll every Twitter notification I get "including RT’s " but If I cant even get this working its not looking hopeful. lol

MrHohenheim · July 8, 2017, 9:03pm

nice… first time i think something at the formatting but idk now

Mr-G · July 8, 2017, 9:10pm

Have you guys tried this one thats included in the scrollphathd examples ?

github.com

pimoroni/scroll-phat-hd/blob/master/examples/twitter-hashtag.py

MrHohenheim · July 8, 2017, 9:29pm

ofc i used this and not works i see only 2 :: and i tryed this one at the forum and same result

Bugman_140 · July 8, 2017, 10:10pm

yea same here, I just get 2 or 3 :: sometimes followed by a .
but no text displayed.

thanks for your help

MrHohenheim · July 9, 2017, 9:27am

i hope someone can fix this problem :)

alexmburns · July 28, 2017, 11:42pm

Firstly, massive thanks for making this script. I spent so long tinkering about trying to make my own and yours worked first time!

I was just wondering if there is something simple I could add into the code so it scrolled the last message found on repeat until a new message is received. I was hoping to use it like a notifications board but unless someone happens to be there when I send the tweet all they would see is a blank screen.

Kind regards,

Alex

fhernand · August 19, 2017, 1:08pm

I had the same problem and spent some time trying out changes to the code. At the end what worked is changing the font from “font5x7smoothed” to “font5x7”.
