<p>B8XMWPcrhZ: </p> <hr /> <div>This page contains a list of things people wish PineTime did differently<br /> <br /> === Hardware ===<br /> <br /> * Long pressing the button should power-cycle the watch without any software being involved<br /> * Used sensors should be NDA-free and preferably also blob-free<br /> * 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?<br /> * 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.<br /> * 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 coördinates 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!<br /> * A full redraw on the display takes 120ms at the very least, which is 8Hz. A smooth scrolling/usage/animation experience would be 30Hz minimum, preferably 60. I heard a rumor that the SPI connection to the display is a bottleneck. Can this be fixed?<br /> * Some sort of scroll wheel would be nice for convenience.<br /> * Changed GPIO assignment so more functionality is available (i.e. NFC and VSYNC)<br /> * Wireless charging, or Qi Charging capability<br /> * An external RTC circuit saving the current time to allow the main MCU go to deep-sleep.<br /> * nrf52840 update, that'll allow SPI x4 speed faster than nrf52832 and moreeeee RAM.<br /> * nRF5340 update: QSPI, CryptoCell + Secure Key Storage, moreeeee RAM, coprocessor, possibility to expose USB through power pins<br /> * version without sensors but maybe bigger battery<br /> * A couple of pins on the programmer connector to allow UART while developing (currently there is a TX test point on PCB).<br /> * Connect the pin of LCD controller that allows RD/WR from it in order to save RAM on the MCU.<br /> * LCD must be centered on case. Currently is not and watchfaces seems different when clock is put on the other wrist.<br /> * A NFC antenna around the case, connected to the NFC pins.<br /> * BMA421 accelerometer doesn't have a datasheet (it seems private to some hardware integrators): take it off and put alternative with open documentation.<br /> <br /> <br /> [[Category:PineTime]]</div>
