I have turned my #pimoroni #presto into a digital photoframe. Images are uploaded to it through #MQTT So the pimoroni frame can in principle be placed "anywhere on the internet" with mqtt broker access, and then you can upload images to it from afar.

I plan to publish the code on github in the next few days.

What if my falling sand particles animation code had an option to leave trails? #pimoroni #presto #RaspberryPi #MakerMonday #RP2350 #Pico #mayke #coding #graphics

This is a curse of compromises but at least I now have options. Using PSRAM , I converted my bouncing balls simulation to run at the full #Presto screen resolution of 480x480 with my anti-aliasing code. Graphics look beautiful, but screen refresh rate dropped to 10 fps due to the time taken to copy the drawing buffer in PSRAM to the screen buffer in the main RAM. Compare this to using a 240 x 480 resolution for buffers all in main RAM where I get 56 fps. #RaspberryPi #pico2 #rp2350 #pimoroni

Circles on a screen, with text showing the ball count in the simulation (12), screen resolution (480x480) and fps (9.75)

Oh my! I’ve managed to get the drawing buffer into PSRAM using the #pimoroni graphics library on the #Presto. This enables full 480 x 480 resolution graphics with a double buffer in C++! #RaspberryPi #pico2 #RP2350

Using #FreeCAD, I designed a cover for my #Pimoroni explorer, which I then printed on my #crealityk1 printer.

The 5 hours waiting for child to be discharged from hospital resulted in a first implementation of my animations library on the #Pimoroni #Presto. A quirk of my graphics library leaves a remnant of the pattern as anti-aliased pixels fail to be cleared to black. #gol

I’ve now put my AA graphics library together with my C++ touchscreen and IMU hardware drivers to implement gravity in my balls simulation on the #Pimoroni #Presto

Not content with this success, I went on to write a pico C++ driver for the lsm6ds3 accelerometer using the pimoroni-i2c library as there did not appear to be any C++ drivers in the wild for this on #rpipico
This along with the touch screen C++ driver I converted from lvgl to the pimoroni-pico graphics will be published in my #presto examples once I have fully implemented the driver and written some simple boilerplate examples.

I released some code!

I‘ve pushed my little python script for the pimoroni Inky Impression to my GitHub

I never imagined that drawing antialiased circles could be so difficult. Another 4 hours debugging and I’m getting there. Just drawing the antialiased edge pixels here to test. #presto #pimoroni #coding #pico

Now I am here - I will plug my current project!

Are you looking for a weekend project?
Do you have Spotify Premium?
Do you have the #Pimoroni #Presto screen?

Then why not see if you can get my #Spotify project running?

https://github.com/vwillcox/Presto-nowplaying

Features:
* Artist Name
* Track Name
* Album Artwork
* Pause/Play Button
* Skip Button

After a lot of work it now has the text formatted and aligned
It also has the album artwork aligned on the screen!

Hello World!

But I had to build it twice, as Home Assistant OS for Pi4 and Pi5 is different - here I thought I could just swop the SSD 🤦.

Rest went smooth - what a beaut and a waste to hide inside a cupboard!

This weeks stupidity… I made a mini 5u HomeLab for my HomeAssistant and PiHole boxes that sit inside an Ikea storage crate.

Includes a Pi5 16GB, Pi 3b+, Pi Zero W2 and a Pimoroni Badger for stats.

Tages-Kalender-Projekt:
E-Ink Display läuft als Raspi-Shield. Kalender-Termine kommen rein über Google-API, Bild wird generiert und ans Display geschickt (alles Python).
Fehlt noch ein Halter/Rahmen. Dann muss ich schauen wie ich das mache mit täglichen Updates. Laufen lassen und morgens "hydrieren"? Dann wäre das Raspi 23,9 Stunden am Tag sinnlos an. Vllt. gibts ne simple Lösung dass es mogentlich kurz an geht, das Display updatet, und sich wieder shutdownt. #raspberrypi #pimoroni #eink

Around 2 weeks of my free time spent just getting a round antialiased circle to draw on the #pimoroni #Presto screen regardless of the aspect ratio of the back buffer wrt the screen. Finally works with a 240x240, 240x480 and 480x240 resolution double buffer. #C++
