wasp-os and @MicroPython work really great on #PineTime Smart Watch @PINE64 ... Can we make them even better? Let's experiment and find out! https://lupyuen.github.io/pinetime-rust-mynewt/articles/micropython

A little scratch in the Rowdy Playground of #PineTime Smart Watch @PINE64 ...

Now that we're all masked and faceless... What if our #PineTime Smart Watch @PINE64 can light up in colour... When someone with similar interests is nearby? 🤔

wasp-os, @MicroPython, @Apache_Mynewt AND @RustLang... Together on #PineTime Smart Watch @PINE64 with #nRF52 @NordicTweets... So cool! https://github.com/lupyuen/pinetime-rust-mynewt/tree/micropython

We have a @MicroPython Stack Trace on @Apache_Mynewt yay! Testing continues on #PineTime Smart Watch @PINE64 with #nRF52 @NordicTweets https://github.com/lupyuen/pinetime-rust-mynewt/tree/micropython

@MicroPython + Embedded @RustLang + @Apache_Mynewt built successfully yay! Now testing on #PineTime Smart Watch @PINE64 #nRF52 @NordicTweets https://github.com/lupyuen/pinetime-rust-mynewt/tree/micropython

@PINE64 This animation symbolises the creation of #PineTime's free and open source software... Bit by bit

Brainstorming with @minodesign on Bootloader Animation for #PineTime Smart Watch... Did you know that @PINE64 Logo contains exactly 10 parts? Perfect for a Progress Bar! https://github.com/lupyuen/pinetime-rust-mynewt/releases/tag/v4.1.10

Resolving the final few @MicroPython references with @Apache_Mynewt on #PineTime Smart Watch @PINE64 ... Kudos if you know what they mean: etext, ebss, estack 😀 (Hint: Linker Map) https://medium.com/@ly.lee/stm32-blue-pill-analyse-and-optimise-your-ram-and-rom-9fc805e16ed7?source=friends_link&sk=54719084d640bb1d92ac1097d623bba2

Thanks to @minodesign we have a UX Concept for #PineTime Smart Watch Bootloader @PINE64! This Bootloader can be customised to your liking... Let us know what you think!

We have @Apache_Mynewt calling @RustLang calling @MicroPython... So excited to run this on #PineTime Smart Watch @PINE64 https://github.com/lupyuen/pinetime-rust-mynewt/blob/micropython/rust/app/src/lib.rs

Now integrating @MicroPython build into @Apache_Mynewt with Embedded @RustLang and Wireless Firmware Updates... Can #PineTime Smart Watch @PINE64 handle so many goodies? We'll find out! https://github.com/lupyuen/pinetime-rust-mynewt/tree/micropython

Removed all references to Nordic SDK in @MicroPython on #PineTime Smart Watch @PINE64 ... And switched them to @Apache_Mynewt yay! https://github.com/AppKaki/micropython/blob/wasp-os/ports/mynewt/

My thoughts on Arm Cortex-M (#PineTime @PINE64 #nRF52) vs Cortex-A (#RaspberryPi)… Maybe I prefer Cortex-M gadgets because they are simple and teachable 😀 On Raspberry Pi the combination of hardware and software gets too much for a single person to learn 😅

Won't be needing this @MicroPython SPI code on @Apache_Mynewt for #PineTime Smart Watch @PINE64 ... Because Mynewt configures the SPI port through the syscfg.yml build settings file yay! https://github.com/AppKaki/micropython/blob/wasp-os/ports/mynewt/modules/machine/spi.c

Fixing @MicroPython references on #PineTime Smart Watch @PINE64 ... Replacing Nordic SoftDevice by @Apache_Mynewt https://github.com/AppKaki/micropython/tree/wasp-os/ports/mynewt

Right now @JF is testing the new #MCUBoot Bootloader on his #PineTime Smart Watch @PINE64 ... So exciting! 😀 https://lupyuen.github.io/pinetime-rust-mynewt/articles/dfutest

Love the way wasp-os supports #Python REPL over Bluetooth on #PineTime Smart Watch @PINE64 ... So cool! https://www.youtube.com/watch?v=kf1VHj587Mc

@MicroPython Drivers for #PineTime Smart Watch @PINE64 #nRF52... Now porting from Nordic SoftDevice to @Apache_Mynewt https://github.com/AppKaki/micropython/blob/wasp-os/ports/mynewt/Makefile

Porting @MicroPython from Nordic SoftDevice to @Apache_Mynewt on #PineTime Smart Watch @PINE64 ... Starting with GPIO https://github.com/AppKaki/micropython/blob/wasp-os/ports/mynewt/mphalport.h
