## Summary
* Redesigned home screen with big option to continue reading and
slightly nicer options to navigate to core sections
* Attempt to use the cached EPUB details (title, author) if they exist,
otherwise fall back to file name
* Adjusted button hints on home screen, removed Back option and changed
left/right to up/down
## Additional Context
* Core of this work comes from @ChandhokTannay in
https://github.com/ChandhokTannay/crosspoint-reader/commit/1d36a86ef1f016e796ef993c14fb1f9ea2f0101d
## Summary
* Add setting for line spacing to adjust space between lines
* Aleo is already a bit tighter than Noto Sans and Open Dyslexic, so
have adjusted the values to match, this can be tweaked in the future
## Summary
* Show previous title for unnamed spines
* The spec is a little unclear, but there are plenty of cases where
chapters are split up in parts and should show the previous chapter's
title
* List TOC items instead of spine items in chapter select
* Bump `BOOK_CACHE_VERSION` to `2` to force regeneration of spine item's
TOC indexes
## Summary
* Swap to updated SDCardManager which uses SdFat
* Add exFAT support
* Swap to using FsFile everywhere
* Use newly exposed `SdMan` macro to get to static instance of
SDCardManager
* Move a bunch of FsHelpers up to SDCardManager
## Summary
* Consolidate chapter page data into single file
* Header structure of the file stays the same, following the page count,
we now put a LUT offset
* The page data is all then appended to this file
* Finally the LUT is appended to the end of the file, and the page count
is updated
* This will also significantly improve the duration of cache cleanup
which takes a while to scan the directory and cleanup content
* Remove page file version as it's all tied up into the section file now
* Bumped section file version to 7
* Moved section content into sub directory
* Updated docs
## Additional Context
* Benchmarks:
* Generating 74 pages of content from a chapter in Jade Legacy took:
* master: 6,229ms
* this PR: 1,305ms
* Speedup of 79%
* Generating 207 pages of content from Livesuit book:
* With progress bar UI updates:
* master: 24,250ms
* this PR: 8,063ms
* Speedup of 67%
* Without progress bar UI updates:
* master: 13,055ms
* this PR: 3,600ms
* Speedup of 72%
## Summary
* Use font ascender height for baseline offset
* Previously was using font height, but when rendering the font (even
from y = 0), there would be a lot of top margin
* Font would also go below the "bottom of the line" as we were using the
full font height as the baseline
## Additional Context
* This caused some text to move around, I've fixed everything I can
* Notably it moves the first line of font a little closer to the top of
the page
## Summary
* Fix underscore on keyboard
* Remove special handling of special row characters
* Fix navigating between special row items
* Standardize keyboard activity to use standard loop
* Fix issue with rendering keyboard non-stop
Fixes https://github.com/daveallie/crosspoint-reader/issues/131
## Summary
* Use single unified cache file for book spine, table of contents, and
core metadata (title, author, cover image)
* Use new temp item store file in OPF parsing to store items to be
rescaned when parsing spine
* This avoids us holding these items in memory
* Use new toc.bin.tmp and spine.bin.tmp to build out partial toc / spine
data as part of parsing content.opf and the NCX file
* These files are re-read multiple times to ultimately build book.bin
## Additional Context
* Spec for file format included below as an image
* This should help with:
* #10
* #60
* #99
## Summary
* Prevent SD card error causing boot loop
* We need the screen and fonts to be initialized to show the full screen
error message
* Prior to this change, trying to render the font would crash the
firmware and boot loop it
## Summary
* Handle 16x16 MCU blocks in JPEG decoding
* We were only correctly handling 8x8 blocks, which means that we did
not correctly support a lot of JPGs leading to an interlacing style on
the images
## Additional Context
* Fixes https://github.com/daveallie/crosspoint-reader/issues/118
## Summary
* Adds support for OTA
* Gets latest firmware bin from latest GitHub release
* I have noticed it be a little flaky unpacking the JSON and
occasionally failing to start
## Summary
* HTML files are now static, streamed directly to the client without
modification
* For any dynamic values, load via JSON APIs
* For files page, we stream the JSON content as we scan the directory to
avoid holding onto too much data
## Additional details
* We were previously building up a very large string all generated on
the X4 directly, we should be leveraging the browser
* Fixes https://github.com/daveallie/crosspoint-reader/issues/94
## Summary
* Give activities name and log when entering and exiting them
* Clearer logs when attempting to debug, knowing where users are coming
from/going to helps
## Summary
* Swap from `wasReleased` to `isPressed` when checking power button
duration
* In practice it makes the power down experience feel a lot snappier
* Remove the unnecessary 1000ms delay when powering off
## Additional Context
* A little discussion in here:
https://github.com/daveallie/crosspoint-reader/discussions/53#discussioncomment-15309707
## Summary
* Fix incorrect justification of last line in paragraph
* `words` is changing size due to the slice, so `isLastLine` would
rarely be right, either removing justification mid-paragraph, or
including it in the last line.
## Additional Context
* Introduced in #73
## Summary
* Unset openEpubPath on boot and set once epub fully loaded
## Additional Context
* If an epub was crashing when loading, it was possible to get the
device stuck into a loop. There was no way to get back to the home
screen as we'd always load you back into old epub
* Break this loop by clearing the stored value when we boot, still
jumping to the last open epub, but only resetting that value once the
epub has been fully loaded
## Summary
- Add basic JPG image support
- Map JPG back to 2-bit BMP output
- Can be used to later render the BMP file from disk or directly pass to
output if wanted
- Give the 3 passes over the data needed to render grayscale content,
putting it on disk is preferred to outputting it multiple times
## Additional Context
- WIP, looking forward to BMP support from
https://github.com/daveallie/crosspoint-reader/pull/16
- Addresses some of #11
## Summary
* Paginate book list
* Avoid out of bounds rendering of long book titles, truncate with
ellipsis instead
## Additional Context
* Should partially help with
https://github.com/daveallie/crosspoint-reader/issues/75 as it was
previously rendering a lot of content off screen, will need to test with
a large directory
## Summary
* Extract EPUB TOC into temp file before parsing
* Streaming ZIP -> XML parser uses up a lot of memory as we're
allocating inflation buffers while also holding a few copies of the
buffer in different forms
* Instead, but streaming the inflated file down to the SD card (like we
do for HTML parsing, we can lower memory usage)
## Additional Context
* This should help with
https://github.com/daveallie/crosspoint-reader/issues/60 and
https://github.com/daveallie/crosspoint-reader/issues/10. It won't
remove those class of issues completely, but will allow for many more
books to be opened.
## Summary
* Build out lines for pages when holding over 750 buffered words
* Should fix issues with parsing long blocks of text causing memory
crashes
## Summary
* Previously, only pure black pixels in the font were marked as black,
this expands the black range, and makes the lightest pixels white
## Additional Context
* Noticed personally it was kind of "thin" and washed out a bit, this
massively helps, should also address concerns raised here:
https://github.com/daveallie/crosspoint-reader/discussions/39
## Summary
* This PR drastically reshapes the structure of the codebase, moving
from the concept of "Screens" to "Activities", restructing the files and
setting up the concept of subactivities.
* This should help with keep the main file clean and containing all
functional logic in the relevant activity.
* CrossPointState is now also a global singleton which should help with
accessing it from within activities.
## Additional Context
* This is probably going to be a bit disruptive for people with open
PRs, sorry 😞
## Summary
- When allocating the `bwBuffer` required to restore the RED RAM in the
EPD, we were previously allocating the whole frame buffer in one
contiguous memory chunk (48kB)
- Depending on the state of memory fragmentation at the time of this
call, it may not be possible to allocate all that memory
- Instead, we now allocate 6 blocks of 8kB instead of the full 48kB,
this should mean the display updates are more resilient to different
memory conditions
## Additional Context
Added Github templates for PRs and bugs
Also added one for funding, please do not feel obligated to
donate to the project, this is not a for-profit endevour, I
just had someone ask where they could send a few dollars so
I have set it up
* First pass at moving to SDK EInkDisplay library
* Add 2-bit grayscale text and anti-aliased rendering of text
* Render status bar for empty chapters
* Refresh screen every 15 pages to avoid ghosting
* Simplify boot and sleep screens
* Give FileSelectionScreen task more stack memory
* Move text around slightly on Boot and Sleep screens
* Re-use existing buffer and write to whole screen for 'partial update'
