Read, write and erase SPI Flash with @Apache_Mynewt on #nRF52 @NordicTweets and #PineTime Smart Watch @PINE64 ... Easy peasy! https://lupyuen.github.io/pinetime-rust-mynewt/articles/spiflash

Tiny tweak to @Apache_Mynewt that enables SPI Flash... Works on #PineTime Smart Watch @PINE64 and other #nRF52 boards @NordicTweets https://lupyuen.github.io/pinetime-rust-mynewt/articles/spiflash

Here's how we configure the SPI Flash Interface on @Apache_Mynewt... Works for #PineTime Smart Watch @PINE64 and any #nRF52 board @NordicTweets https://lupyuen.github.io/pinetime-rust-mynewt/articles/spiflash

Groovy Backlight Animation with #RustLang on #PineTime Smart Watch @PINE64 ... All GPIO, no SPI... So that we can better utilise SPI bandwidth for flashing PineTime https://github.com/lupyuen/pinetime-rust-mynewt/blob/ota2/rust/app/src/display.rs

Writing the steps to access SPI Flash on @Apache_Mynewt... Works on any #nRF52 board @NordicTweets, including #PineTime Smart Watch @PINE64 ... Stay tuned! https://lupyuen.github.io/pinetime-rust-mynewt/articles/spiflash

Configure @Apache_Mynewt for SPI Flash? No sweat! Here's how I did it for #PineTime Smart Watch @PINE64 based on #nRF52 @NordicTweets https://github.com/lupyuen/pinetime-rust-mynewt/blob/ota2/hw/bsp/nrf52/syscfg.yml

SPI Flash works on #PineTime Smart Watch @PINE64 yay! Tested with @Apache_Mynewt https://github.com/lupyuen/pinetime-rust-mynewt/blob/ota2/apps/my_sensor_app/src/flash_test.c

I miss durian (that's Red Prawn in the pic)

Here's how we'll test SPI Flash on #PineTime Smart Watch @PINE64 with @Apache_Mynewt https://github.com/lupyuen/pinetime-rust-mynewt/blob/ota2/apps/my_sensor_app/src/flash_test.c

Testing Flash Memory speed with @Apache_Mynewt... For Internal Flash ROM and External SPI Flash on #PineTime Smart Watch @PINE64 https://github.com/apache/mynewt-core/blob/master/test/flash_test/src/flash_test.c

SPI Flash settings @Apache_Mynewt for #PineTime Smart Watch @PINE64 ... Does this look right 🤔 https://github.com/lupyuen/pinetime-rust-mynewt/blob/ota2/hw/bsp/nrf52/syscfg.yml

Learning to configure External SPI Flash for @Apache_Mynewt on #PineTime Smart Watch @PINE64 ... Is it really so easy? 🤔

Hi #PineTime Firmware Devs: Here are the complete steps for supporting Firmware Updates over Bluetooth... PineTime Owners will ❤️ us for making the PineTime Smart Watch @PINE64 so fun and easy to learn and explore! 😀 https://lupyuen.github.io/pinetime-rust-mynewt/articles/dfu

Android, iOS and #PinePhone Mobile Apps for #PineTime Smart Watch @PINE64 ... How we'll be creating them with open source libraries https://lupyuen.github.io/pinetime-rust-mynewt/articles/dfu

@Raspberry_Pi 4 with 64-bit @Ubuntu Desktop... Querying the firmware installed on #PineTime Smart Watch @PINE64 over Bluetooth LE... Had to plug in a USB Bluetooth dongle though https://lupyuen.github.io/pinetime-rust-mynewt/articles/dfu

Prelim Design for Firmware Update over Bluetooth on #PineTime Smart Watch @PINE64 is now ready! And we're already planning enhancements based on feedback from PineTime FOSS Community... That's how we iterate and create awesome Open Source Products! https://lupyuen.github.io/pinetime-rust-mynewt/articles/dfu

Useful #BluetoothLE GATT Services exposed by #PineTime Smart Watch @PINE64 ... Thanks to the open source MCU Manager Library for @Apache_Mynewt and @ZephyrIoT https://lupyuen.github.io/pinetime-rust-mynewt/articles/dfu

#GNOME Toolkit on #GoLang with #VSCode and 64-bit @Ubuntu Desktop for @Raspberry_Pi 4 https://github.com/gotk3/gotk3-examples/blob/master/gtk-examples/stack/stack.go

Preventing #PineTime Smart Watch @PINE64 from getting bricked during Firmware Update... #MCUBoot Bootloader is the solution https://lupyuen.github.io/pinetime-rust-mynewt/articles/dfu
