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

Beautiful sourdough starter

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

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

I'm now using #Ubuntu 20.04 on #Raspberry 4...

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