For those of you who dont have the #include<animation.h> library

you can use the code below: (to create your own custom animation youll just need to calculate the values)

#include "Arduino_LED_Matrix.h"

#include <stdint.h>

ArduinoLEDMatrix matrix;

const uint32_t frames[][4] = {

{ //13

0x0,

100

{ //12

0x0,

0x10010010,

0x1001000,

100

{ //11

0x100,

0x20020030,

0x2002001,

100

{ //10

0x300,

0x40040070,

0x4004003,

100

{ //9

0x600,

0x900900F0,

0x8009006,

{ //8

0xC01,

0x201201E0,

0x1001200C,

{ //0

}

};

void setup() {

Serial.begin(115200);

}

void loop() {

// you can also load frames at runtime, without stopping the refresh

matrix.loadSequence(frames);

matrix.begin();

// turn on autoscroll to avoid calling next() to show the next frame; the parameter is in milliseconds

// matrix.autoscroll(300);

matrix.play(true);

}

Hi, do you know how to compile and upload sketch via wifi with R4 wifi? something like OTA for Uno Wifi docs.arduino.cc/.../ota-getting-started

Nice demo.

I spent a lot of time bit mapping symbols on the early microcontrollers back in the 1980's.

Nice blog on the new boards. I am still waiting for my board to arrive (I guess shipping to Texas is slower than around the coasts). Thanks for sharing your first impressions!

I did a quick test to see how quickly the R3, R4 Minima, and R4 WiFi compiled and uploaded. I'm using the "blink" sketch and two different IDE versions without modification. Here are the results:

It isn't really what I expected. The Arduino IDE version being used makes a huge difference with the R3. It drops from around 15 seconds in the older version 1.8.57.0 down to something more than 2 seconds in the newer version 2.1.1. I haven't used the Arduino IDE in quite some time and installed the latest version to test the R4. Another surprise was that the WiFi version was faster than the Minima. I'd be interested if others see the same thing or if I'm doing something off.
