From 4cc260251c40bef3fed778a078862ab419917dcd Mon Sep 17 00:00:00 2001 From: Ace Date: Mon, 25 Feb 2019 22:14:16 +0100 Subject: [PATCH] Improved snippet for fetching & displaying events Contains a lot of minor improvements like better output, fixing some 'crude' sections. The algorithm for fetching events has been improved (faster) and is more dynamic. Users can specify the range in days for fetching events form the future. Also fixed a bug where past events were not marked with circles on the monthly calendar. Also improved some output messages. --- Calendar/E-Paper.py | 70 ++++++++++++++++++++++----------------------- 1 file changed, 35 insertions(+), 35 deletions(-) diff --git a/Calendar/E-Paper.py b/Calendar/E-Paper.py index 305fd51..8bbaf47 100644 --- a/Calendar/E-Paper.py +++ b/Calendar/E-Paper.py @@ -9,7 +9,7 @@ Copyright by aceisace """ from __future__ import print_function import calendar -from datetime import datetime +from datetime import datetime, date, timedelta from time import sleep from settings import * @@ -41,7 +41,6 @@ im_open = Image.open """Main loop starts from here""" def main(): while True: - time = datetime.now() hour = int(time.strftime("%-H")) month = int(time.now().strftime('%-m')) @@ -49,14 +48,13 @@ def main(): for i in range(1): print('_________Starting new loop___________'+'\n') + """At the following hours (midnight, midday and 6 pm), perform a calibration of the display's colours""" - if hour is 0 or hour is 12 or hour is 18: - print('performing calibration for colours now') calibration() - print('Date:', time.strftime('%a %-d %b %y')+', time: '+time.strftime('%H:%M')+'\n') + print('Date:', time.strftime('%a %-d %b %y')+', Time: '+time.strftime('%H:%M')+'\n') """Create a blank white page, for debugging, change mode to to 'RGB' and and save the image by uncommenting the image.save @@ -97,11 +95,9 @@ def main(): image.paste(im_open(dpath+str(numbers)+'.jpeg'), positions['d'+str(cal[3].index(numbers)+1)]) for numbers in cal[4]: image.paste(im_open(dpath+str(numbers)+'.jpeg'), positions['e'+str(cal[4].index(numbers)+1)]) - try: + if len(cal) == 6: for numbers in cal[5]: image.paste(im_open(dpath+str(numbers)+'.jpeg'), positions['f'+str(cal[5].index(numbers)+1)]) - except IndexError: - pass """Custom function to display text on the E-Paper.
