Jvandermey: Added information for all firmware releases to date

== InfiniTime ==
InfiniTime (also known as JF's project, FreeRTOS firmware or Pinetime-JF) is an open source (GPLv3) firmware written in C++ and based on FreeRTOS, LVGL and NimBLE. This firmware (version 0.7.1) is preloaded at the factory since the new batch of PineTime devkits and sealed PineTimes of end of September 2020. '''This page contains general information about the project. Actual project documentation and nuances are documented in the repository'''

== Read this first! ==
* InfiniTime and the bootloader are still in heavy development, and some features might not work as expected. Any issues should be reported on GitHub.
* Do not use a sealed PineTime as a development device, there is a fair amount of chances that you'll brick it with very experimental firmware.
* OTA is relatively stable, but when you're on an outdated bootloader version it can freeze which will require you to wait for the battery to run out.

== Known issues ==
{{warning|1=Please read this section carefully before upgrading the firmware on your PineTime, especially if you are using a sealed device!}}
=== Black screen after a reset in sleep mode ===
==== Description ====
This issue occurs if you are using the original bootloader (from InfiniTime 0.7.1), upgraded from InfiniTime 0.7.1 to 0.8.2 and the watch resets while the display is OFF : the watch is stuck on a black screen and does not respond to touch, button press or BLE.

The reset can be triggered by the watchdog or manually by long pressing the button. If that doesn't work, wait for the battery to run out, it'll reboot then.

This issue is caused by InfiniTime 0.8.2 that put the external SPI flash memory to sleep before switching the display off and by the bootloader that cannot wake the memory chip up. The bootloader is stuck in an infinite loop.

More info : https://github.com/lupyuen/pinetime-rust-mynewt/issues/24 and https://github.com/JF002/InfiniTime/issues/60

==== Workaround ====
On a development kit, a simple reset via SWD is needed to unlock the bootloader.

On a sealed device, the only way to work around this issue is to wait for the battery to drain completely before trying again.

This issue can be avoided by ensuring that the display is ON when manually resetting the device (long push on the button).

==== Fixed version ====
This issues is fixed in [https://github.com/JF002/InfiniTime/releases/tag/0.8.3 InfiniTime 0.8.3]

Jvandermey:

This page contains a list of things people wish PineTime did differently

=== Hardware ===

* Long pressing the button should power-cycle the watch without any software being involved
* Other display tech could be explored. [//en.Wikipedia.org/wiki/Transflective_liquid-crystal_display A transflective LCD] would probably be a nice option. Or potentially OLED?
* Touchscreen should possibly have a configurable sensitivity level for both glove-wearing and droplet-resistance. Preferably it should still be a capacitive one, a resistive touchscreen would have too many trade-offs.
* A slightly bigger 256×256 pixel graphics display size is preferable for its binary alignment, affording some low-level simplicity – it has the property that its X and Y coordinates are each addressable with a single byte, with no out-of-bounds; its total number of pixels is 65536 (another power of 2), and each pixel is addressable with exactly 2 bytes, with perfect efficiency. The [http://Pelulamu.net/ibniz IBNIZ (Ideally Bare Numeric Impression giZmo) virtual machine], designed for fun minimalist demoscene graphics, has chosen 256×256 for its virtual display, and makes use of these simplicity advantages. If PineTime also chose 256×256 then it would be a target platform for unclipped IBNIZ demoscene programmes, which would be really fun to play around with on one's wrist!
* A full 16-bit redraw on the display takes 120ms at the very least, which is 8Hz (although modest optimization is possible by adopting 12-bit color). A smooth scrolling/usage/animation experience would be 30Hz minimum, preferably 60. Display redraw is currently bottlenecked by the nRF52832 maximum SPI clock (8MHz).
* Some sort of scroll wheel would be nice for convenience.
* Changed GPIO assignment so more functionality is available (i.e. NFC and VSYNC)
* Wireless charging, or Qi Charging capability
* An external RTC circuit saving the current time to allow the main MCU go to deep-sleep.
* nRF5840 update: QSPI, CryptoCell + Secure Key Storage, has more RAM, a coprocessor and the possibility to expose USB through power pins
* Preferably a pre-certified MCU module with a ceramic antenna
* Version without sensors but maybe bigger battery
* A couple of pins on the programmer connector to allow UART while developing (currently there is a TX test point on PCB). (Note: There's ARM SemiHosting and Segger RTT)
* Connect the pin of LCD controller that allows RD/WR from it in order to save RAM on the MCU. (The MOSI pin for the SPI is already connected to the nor flash that shares the same pins, pin number is P0.04)
* LCD must be centered on case. Currently is not and watchfaces seems different when clock is put on the other wrist.
* A NFC antenna around the case, connected to the NFC pins.
* Used sensors should be NDA-free and preferably also blob-free. For example the BMA421 accelerometer doesn't have a datasheet (it seems private to some hardware integrators): a more open one would be much easier to develop for. Special attention should be paid to advanced features, such as step counting integration or flick detection.
* PineTime SoC could support USB or have a FTDI chip with the relevant pins exposed. It could allow flashing a sealed device, just like Arduinos work. The same USB-C could also be used for charging.
* A bigger pulldown resistor for the power button, because 100k still leaks a noticeable amount of power when the button is always on.
* Ceramic Bluetooth antenna for better signal reception
* Ultra low quiescent current PMIC for better deep sleep. Better shipping/storage/turned off mode
* Separate RTC chip to maintain time setting through MCU reset
* Battery charger IC with built-in "fuel gauge" functionality for better estimation of battery capacity
