Raspberry Pi Pico Animations on OLED displays using CircuitPython

Raspberry Pi Pico Animations on OLED displays using CircuitPython

There are many ways to load and display an animation on an OLED screen, either with Arduino or CircuitPython. I am going to show you what I think is the easiest way to achieve it. I will work with the monochrome OLED, but the procedure works with the Color one as well with only one minor difference that I will show you later in this video.

Good work. Back in 2017 I learned how to display bitmap image on Nokia lcd from your tutorials.

[Tims_Projects]

Great stuff. Love what you are doing with CIrcuitPython.

[avejst]

Great find
Great video as always
Thanks for sharing your experiences with all of us 🙂

Yasou Nick! Summers in Kim’s, Evian😁 Great video. I joined your other channel too. Looking forward to more videos.

If you take out the micro usb will the animation run independently with a separate power source

Have you had any luck connecting multiple oleds to a pico ?

Is there a faster way to display gifs? the animation playback is quite slow this way. When i was using micropython i was able to play at 60fps by using blit with individual frames

Great, I am using micropython and i cannot upload bmp file, do i have to switch to circuit python for this feature?

[dannguyen]

Do you think i can do the same if I have Feather RP2040 board and ST7789 TFT 1.47" display? I have been trying to make Mini gif player with the guide, but couldn't get it to work. So right now I'm trying yours project.

Hi Nick, thank you for making amazing training material.
I have a question about little project i'm doing.

The project has two buttons and a 12v LED strip. One button press needs to start LEDs flash then when the button is pressed again LEDs to stop.
Second button when pressed LEDs will start flashing then stop on its own after few seconds.

How can I go about doing that?

I don't have your email so wrote it here if that ok :)
I'm useing FastLED library and this is my code without buttons (not sure how to make add buttons to make the above operation) :


#include <FastLED.h>
#define NUM_LEDS 60
#define LED_PIN 6

CRGB leds[NUM_LEDS];

void setup() {
FastLED.addLeds<WS2811, LED_PIN, GRB>(leds, NUM_LEDS);
FastLED.setBrightness(1);

}

void loop() {
// Turn the LED on, then pause
fill_solid( leds, NUM_LEDS, CRGB( 255, 255, 255 ) );
FastLED.show();
delay(20);

fill_solid( leds, NUM_LEDS, CRGB( 0, 0, 0 ) );
FastLED.show();
delay(200);

}


Sorry if this is a wrong place to post. Don't have your email.
Thank you :)

Will you make tutorial for micropython too?
I recently bought ESP32 and flashed bootloader to use micropython.
I wonder if this will work with this OLED too.

The "code" link takes you to a page missing links to libraries and it's full of ads.
I'm lost. This didn't help me. How do you define the GP pins used, you don't show that part of the code.
