@PINE64 now supports BLE notifications!

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

Here is the changelog : github.com/JF002/Pinetime/rele

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 .

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 !

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 community = 👍

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

Version 0.3.0 of my C++/#FreeRTOS/#LittleVGL firmware for @PINE64 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 : github.com/JF002/Pinetime/rele

Testing widgets (button matrix, gauge, meter) on my 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 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

Infinite scrolling rainbow on 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!

@PINE64

Experimentation with vertical scrolling (hardware assisted) on

@PINE64

Full screen scrolling:

It was nice to meet the @PINE64 team at today! I've been able to see the pinebook pro and pinephone with my own eyes!

And I met very nice people during the BoF!

I'm happy to release version 0.2.2 of my
based firmware for . It brings improvements, bugfixes and contributions from the community.

@PINE64 there's still time to update before !!!

ULTIMATE performances of the SPI display driver for : 119ms for a full screen refresh. This is not far from the maximum theoretical value of (240 lines * 240 rows * 16 bits) 115.2ms !

@PINE64

Using DMA to drive the SPI display of . It's much faster!

The following video contains 2 clips played in real time, I didn't increase the speed for the second part :)

@PINE64

Debug (and fix) sleep mode issues using a LED.

Tl;DR : do not log & clear FPU interrupt flags before going to sleep.
