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

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

Porting @MicroPython to @Apache_Mynewt has begun! First Target: #PineTime Smart Watch @PINE64 https://github.com/AppKaki/micropython/tree/wasp-os/ports/mynewt
