@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 !

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!

@PINE64

Partial screen scrolling

Experimentation with vertical scrolling (hardware assisted) on #pinetime

Full screen scrolling:

It was nice to meet the @PINE64 team at #FOSDEM2020 today! I've been able to see the pinebook pro and pinephone with my own eyes!

And I met very nice people during the #pinetime BoF!

24 hours later and still right on time!

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

See https://github.com/JF002/Pinetime/releases/tag/v0.2.2

@PINE64 there's still time to update before #FOSDEM2020 !!!

ULTIMATE performances of the SPI display driver for #pinetime : 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 #pinetime. It's much faster!

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

A second batch of homebrewed beer fermented with #jfbrew !

Now, I just have to wait for 2 months before tasting them!

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

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