PIS-OS v5.3

Added

• LED based driver (Akizuki Denshi K875) using crossed over shift registers and a bunch of DMA/MCPWM trickery
• Noritake GU7000 driver can now do blanking instead of full shutdown to reduce repeated strain on the heater filaments
• .env file can now have default WiFi credentials
• Support for incontiguous monospace fonts
• Support for per-character font fallbacks (when a character doesn't exist in a font, find it in other known fonts)
• Load (a hardcoded list of) fonts from LittleFS (bespoke format: Monospace Font a.k.a. MoFo)
• Allow loading translations from JSON files off LittleFS instead of hardcoding them
• Japanese fonts (no more broken track names in FB2K for me yay!)
• Photo gallery

New Ringtones

• Hiiragi Magnetite — Antenna 39: Original, Ringtone

Fixed

• Alarms and other on-screen menus now won't be disrupted by HTTPFVU
• Wordnik and Weather tasks don't block indefinitely waiting for cache
• Pause power management during HTTPFVU
• Avoid doing direct LittleFS calls around the code
• Japanese talking clock now has longer delays in speech

Removed

• Deprecated Beeper::beep_blocking() method is now removed
• Due to SPI Flash vs. PSRAM congestion issues in the font loader, Rev0 and Rev1 silicon of ESP32 is not supported anymore. Things will try their best but eventually explode and fail to boot! Rev3 seems to work just fine for all builds so far.

• Ennio Morricone — My Name Is Nobody

Fixed / Changed

• 12/24h voice setting in menu was actually changing a different parameter
• Sampler can now correctly change the pitch of the sample
• Timer tick doesn't sound weird on minute/hour boundaries anymore
• Headpat behavior is now unified no matter the device class
• melody_item_t is now just 5 bytes in size (was 12 bytes)
• Hook points are now a subset of loop points (saving capacity for later sequencer command IDs)

Added

• Weather app in menu
• 2-day weather forecast view
• Precipitation and pressure charts
• Serial MIDI mode toggle in settings
• Talking clock (in Japanese only, uses AquesTalk Pico: requires a paid license, see readme in lib/nonfree-aquestalk for how to install)
• Advanced text rendering modes: outlined, no background, etc (quite slow for now)
• Sprites and anisprites are now rendered using a Composable rather than direct framebuffer calls

New Ringtones

• Calvin Harris - Acceptable In The 80s
• emon - shake it!
• Omega - Én elmegyek

Fixed

• Going past the max ringing time of an alarm while snoozing doesn't cancel it anymore

v3.0

PIS-OS v3.0 "Skibidi Bop Bop Yes Yes"

Because every alarm clock needs a built-in sampler and remote desktop access!

Added

• Screenshot feature in WebAdmin
• Remote control feature using a crappy Python/Tk based GUI over UDP
• Fully featured 1-bit audio engine (CBA to resolder both clocks I have to make use of the internal DAC. And if I wanted an alarm with MP3 quality audio I'd just use my phone!)

New Ringtones

• Bouken Desho Desho, Gentle Jena, Gammapolisz: reworked for polyphonic driver

• Hiroyuki Oshima - The Ark Awakes From The Sea Of Chaos
• Timbaland - Give It To Me also known as Skibidi Toilet
• PinocchioP - God-ish (神っぽいな)

Changed

• Sequencer format is now more MIDI-like rather than the old format of {frequency, length} due to the new polyphonic sound driver

Removed

• Support for Beeper channels and priorities
• Sequencer object is now shared across all apps

v2.2 codename "Peace Door Ball"

Note: I need to attend to some important work stuff and plan a vacation from now on, so this is the last one for a while — things seem to be stable enough. (I PRAY TO FINALLY PAUSE WORKING ON THIS)

---

Added

• Stopwatch app. Access from menu, Right to start/pause, Down/Up when paused to reset.
• Uptime display under Settings → Status.
• Periodic uptime and free RAM logging.

Changed

• Weighing app now shows arrows when the weight has stabilized rather than when it is zero
• LED of Balance Board is now constantly on when Weighing app is launched, off otherwise
• Periodically blink the LED of Balance Board to keep it awake and connected (Yes you better wire-mod it unless you want to eat batteries like crazy)

Fixed

• Don't furiously blink the LED of the Balance Board upon connection, which congested the Bluedroid queue and made the connection freeze
• Keep the Balance Board alive so that the connection does not get stuck over time and require a reboot of both the board and the clock
• Composable class allows to constrain a Renderable into a part of the screen "automagically". One step ahead to a proper composition engine with rects and all?
• DroppingDigitView class allows to easily draw dropping digit numbers without direct calls to the DroppingDigits trait. (The trait currently remains for use-cases with non-standard easing curves, such as the clock view)

v2.1 codename "Peace Door Gun"

Added

• Support keypad instead of touch plane
• Smart alarm (wake up a bit earlier if motion is detected within a set margin before the alarm's set time) for devices with motion sensors
• Remaining sleep time widget
• Option to set max duration of an alarm so your neighbors don't have to listen to Guitar Hero for the next few weeks if you left for a trip and forgot to turn off the clock :-)
• Sequencer can now loop a ringtone from an arbitrary point and change generator's duty cycle ("timbre")
• Support for connecting to a Wii Balance Board. For now only displays weight.

New Ringtones

• Dougal & Gammer — Guitar Hero
• 蜂屋ななし — シャボン
• Takeshi Abo — Gate of Steiner
• deadballP — 永遠に続く五線譜
• Cream puff — Mermaid girl
• Brisk & Trixxy — Eye Opener

Fixed

• Fix bug when alarm app would continuously call the stop function while animating the fade out, thus potentially stopping a neighboring upcoming alarm
• Alarm struct now uses bitfields instead of bitwise operations
• change_state is now just setting a variable and the actual switch is done in the main thread. Fixes an issue where a timed out alarm would effect in the next alarm timing out at 0ms into the ringing.
• put_fanta doesn't corrupt the source buffer anymore
• StringScroll now pre-renders the whole scrolling string in-memory for the sake of reducing microlag
• Blitting functions now properly skip the out-of-bounds areas of the drawing plane instead of idle-looping through respective pixels, improves microlag, especially when there is a long (200+ character) StringScroll being displayed.
• PSRAM is now being used more agressively; use gralloc when allocating graphics buffers to ensure they are in the fast RAM area.
• Looping point is fixed in most existing ringtones

v2.0

Wow that's a ton of shitcode.

Added

• HID subsystem for buttons or things
• Janky touch panel driver for a 4 zone touch pad on top of the screen (left/right/up/down)

Fixed
