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 :)

@PINE64

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.

@PINE64

Now I can run my #pinetime code on a NRF52-DK for easy debugging and testing!

See https://github.com/JF002/Pinetime/blob/master/doc/PinetimeStubWithNrf52DK.md

@PINE64

I wrote some code for my #Pinetime : add battery level, BLE status and date on screen, and use the push button to enable/disable display and sleep mode !

Til you can play Dune2 on Linux thanks to Dune Legacy project!

#pinetime retrieves time from NRFConnect running on my phone!

CTS client (Current Time Service) is up and running... But the code needs a lot of improvements!

@PINE64

Yesterday, I received my development kit for #pinetime from @PINE64 !

Let's see what I can do with it!

Modification of the screen enclosure of my #RaspberryPi for #HifiBerry Digi+ and #PiCorePlayer !

Yesterday was beer bottling day! #JFBrew regulated the temperature of the fermenting beer for more than 500 hours!
Now, the beer is fermenting for the last time in the 28 bottles.
I can't wait to taste them... in 6 to 8 week

#M5FoodsAndDrinks

The temperature regulation is near perfect, and the graphs are beautiful!

#JFBrew

D+1 : It's bubbling, guys! It's BUBBLING! Can you see it?!

#JFBrew

I did it! Finally, I brewed my first ever beer! It now fermenting (I hope...) under the supervision of #JFBrew, my fermentation chamber project based on #ESP32 and #M5Stack!

Which me luck!

Everbody should know about #Heimdall (https://heimdall.site/) : a simple and nice and easy to selfhost application dashboard.

Uh?

#FirstGIFofMyLife!

#JFBrew, Up and running for more than 73 hours!

The temperature regulation is good : max 0.5°C from the set point!

Oh and I've written a script that export all data from #MQTT to #InfluxDB to monitor the process with #Grafana!

My fermentation chamber for #beer project is progressing well : "good enough" temperature regulation, data logging, real-time monitoring, #Mastodon bot for notification,...

Using #ESP32 / #M5Stack, #MQTT, #Python,...

#JFBrew

Debugging #ds18b20 (OneWire) communication...

I've received my package from #M5Stack : M5Fire, M5Cam, LAN module, charging base & USB-TTL!

I just need to find some time to play with these new toys !!
