json template url + file implementation.
The file contains the json template, and can contain variables that will be extracted from the json in the url. The url is fetched at regular intervals.
- apconfig: configure night time, where the system is not updating tags, and the tags are sleeping
- fixed bug calculating expected checkin
- throttle down apinfo update to once per minute
- fixed too many concurrent requests getting tagtypes
- resend current image when a tag reboots and the content type is 'static image' (all other content types were already regenerating the content)
- fixed timing of main loop
* Reduce code size by removing nullptr assignments
* Optimize tagDB for loops
* More tagDB optimizations
* Remove static from language arrays reducing RAM by 5128b
- Reduces Flash by 13060b
* Add missing extern in tag_db.h
* Fix deprecation warning of sntp.h
* Remove static from contentmanager, reduces RAM by 184b
* Use string reference in prepareDataAvail
- Remove some unneeded buffers
- Remove some gotos
- AP info screen content card. Can run on any tag.
- now, you can use {variables} in the 'text' entries in a json template. You can set variables via a http call. If you update a variable, all tags with a json template containing that variable get updated.
- font name in json template is more flexible. You can just use 'filename.ttf' or 'filename.vlw'. A full path is still possible.
- colors in the json template can now be set using #rrggbb color values, and using 'black', 'white' or 'red'.
- added direct output for the TFT display for the yellow esp32-s3. No file writes needed.
- added POST variable 'ttl' to json template upload and image upload, to set the next checkin time
- added /variables-demo.html to demonstrate the variables.
- json templates received from jsonupload are now saved in /current, and reused.
- known issue: 'backup db' button doesn't work due to some browser policy change. Fixing.
thanks to @steinwedel for the inspiration on the variables and some other fixes.
- new: tagtypes are be defined via json in /tagtypes instead of hardcoded
- content template is moved to the tagtype definition
- optimalisation of spr2buffer (also uses psram now, if available)
- bugfixes in spiffseditor
- size fix in painter screen for large screens
- don't display '01-01' in google calendar when start=0
- bigger buffer for json template
- hold generating new content if free space in file system is too low
- tiny bug on failing to color lines red in google calendar for current appointments
- small layout fix current weather on 4.2"
- qr code content enabled again
- turned off temperature on esp32
- http 409 on http POST during OTA
- finetuning buitenradar scale and refresh time
- follow redirects on jsontemplate http call
- cleanup font in flash. Don't forget to update content_template.json in the file system after updating fw.
- fix layout issue in update window
- better error handling + auto retry during fw update
- fixed spelling 'weemos' -> 'wemos_d1_mini32' in build name
To be able to store more images and never worry about running
out of storage again we are adding support of SDCards.
We are faced with two options:
1) Remove the LittleFS code
2) Allow for both FSs but increase the app partition as we run
out of space.
We have opted for 2 for two reasons:
1) Unformated SDCards can be initialized from the littleFS
2) If the SDCard and the flasher share the same SPI pins
the SDCard needs to be completely disconnected so there needs
to be a FS in that rare case.
Performance wise the SDCard is not slowing the system down.
Writing the AP db with 70 APs takes 2.5 seconds, on the SD
only 800ms. This however is SD and setup depending.
By default the SDCard is expected on pins 18,19,23 however this
is configurable via preprocessor defines.
Globally we replace LittleFS with a new pointer to the currently
used FS allowing for hotswapping where the FS pointer is not saved.
One case which is therefore not working is the SPIFSEditor which
copies the FS interally.

- added Swedish å Å to Bahnschrift20 and 30
- option to turn dither on/off in 'static image'
- major overhaul of contentmanager.cpp, content is now generated from json template.
- fallback to 1bpp for 4.2" when no psram
- added 4.2" content layouts
- fixed small apconfig bug
- pause content generation for 60 seconds after crash, to prevent uncontrollable boot loop
- fonts re-rendered: added äöüßÄÖÜ.
- shuffled a bit with fonts to optimize disk usage
- ability to delete files during OTA
- prettify tagDB.json
- error handling in get_DB
- small cosmetic changes
* Due to new ability to delete files: After firmware update via OTA, please perform an OTA update of the filesystem again to perform the deletion of unneeded fonts.
* If updating via platform.io: don't forget to update the filesystem image.
- add: syncing data segment of non-image datatypes between AP's
- add: syncing metadata and deletions between AP's
- sorted tags on the webpage by alias
