A new @PINE64 family member has arrived! #pinetime #pinephone @UBports

Preview of the next version of Pinetime-JF : integration of the motion sensor and step counter in a nice chart !

Thanks to @atc1441 for his precious help on the implementation of the motion sensor!

#pinetime
@PINE64

Using my NRF52-DK board along with NRF Sniffer and #wireshark to debug #BLE connectivity issues between Android and @PINE64 #Pinetime.

Just 1 hour ago, I totally ignored this was possible!

This is so satisfying : connecting and sending notifications from #Gadgetbridge to #pinetime !!!

#notetomyself : video looks better when the brightness is set to low on the pinetime :D

I've just released version 0.6.0 of Pinetime-JF. The big feature of this release is #OTA over #BLE, using #Nimble and #MCUBoot. Thanks to @lupyuen for its hard work on integrating MCUBoot into a firmware for @PINE64 #Pinetime!

https://github.com/JF002/Pinetime/releases/tag/0.6.0

We did it! Here is a little demo of #OTA update over #BLE for @PINE64 #pinetime. This video shows @lupyuen #MCUBoot based bootloader, Pinetime-JF beeing updated by a new version of the firmware and then by @lupyuen firmware. The video is a bit long, but... Enjoy!

Because everyone love progress bars, here is my OTA firmware transfert for @PINE64 #pinetime with a new screen with a #progressbar!

PS : the video has been accelerated

One step at a time to OTA firmware update in @PINE64 #pinetime : The implementation of the DFU protocol (using #nimble BLE stack)!

Now that I can receive a new firmware via BLE, I need to figure out how to store it on the external flash, and maybe swap it with #MCUBoot.

Trying #mcuboot on NRF52832 : Run first image that prints "AAA", upload a new image that prints "BBB", reset and run MCUBoot again, and see that the new image has been started!

This is part of my researches for a bootloader for @PINE64 #pinetime!

@PINE64 #Pinetime now supports BLE notifications!

Release 0.4.0 brings BLE notifications, nice icons, brightness and sysinfo apps and bugfixes!

Here is the changelog : https://github.com/JF002/Pinetime/releases/tag/0.4.0

Any contribution to improve the UI is more than welcome. Next step : OTA!

LPT : forget about the bad news and work on a fun project like @PINE64 #pinetime.

Here's my latest achievement : time synchronization and BLE notification from a Linux computer to the Pinetime.

This is the beginning of a Linux companion app for the Pinetime, yay!

Tasting of 'La Jean-Frost', my second beer fermented thanks to JFBrew, my DIY beer fermentation chamber based on #M5Stack #ESP32 !

Sticker by my lovely fiancee <3

It's a barleywine, 7.9% alcohol and... it taste really good!

How to change a weakness (slow refresh rate) into a nice feature : implement a nice scroll transition when the screen needs to be fully refreshed!

Hardware vertical scroll + LittleVGL + @PINE64 #pinetime community = 👍

Credits to https://github.com/bosmoment/PineTime-apps for the idea!

Version 0.3.0 of my C++/#FreeRTOS/#LittleVGL firmware for @PINE64 #pinetime is available!

The major change is the integration of LittleVGL as UI lib. It contains 5 demo apps showing the capabilities of the firmware and of the device!

Release Note : https://github.com/JF002/Pinetime/releases/tag/v0.3.0

Testing #littlevgl widgets (button matrix, gauge, meter) on my #pinetime firmware !

Also notice that the refresh time has been improved thanks to many optimizations on the SPI driver and LVGL integration!

And I've found a way to disable auto-focus on my camera! Yay!

@PINE64

Debug and timing analysis of my #pinetime firmware using my brand new Saleae Logic 8 !

This pretty little thing will be very helpful to improve battery life, timings, performances and debugging!

@PINE64

First integration of #littlevgl in my #pinetime firmware, with basic user interaction.
@PINE64

Full speed and flicker-free!

Infinite scrolling rainbow on #pinetime using hardware vertical scrolling.

The colors are generated dynamically, instead of just looping the same buffer over and over again.
It requires only a single line buffer!
