For those trying to use these on an Arduino with an atmega328p microcontroller (eg., Uno, Nano, Pro Mini etc.) I have tested the following and found it to work: Connect the wiring as per the hardware WIKI as shown below (right column is the Arduino pins). VCC 3.3V GND GND DIN D11 CLK D13 CS D10 DC D9 RST D8 BUSY D7 In the Arduino IDE, go to the Library manager, and install the GxEPD library. To use a selection of fonts, also install the Adafruit GFX library. In your sketch, use the declarations as follows: // From GxEPD library: #include #include // 1.54" black and white #include #include // From Adafruit GFX: #include // For other fonts and sizes, look in the Adafruit GFX library files in the Fonts directory // These declarations match the WIKI hardware connections: GxIO_Class io(SPI, /*CS=*/ 10, /*DC=*/ 9, /*RST=*/ 8); GxEPD_Class display(io, /*RST=*/ 8, /*BUSY=*/ 7); void setup() { display.init(115200); } void loop() { display.drawPaged(showPageOfSomething); delay(5000); } void showPageOfSomething() { float t = 24.5; // randomise these if you want the display to change. float h = 56.0; display.fillScreen(GxEPD_WHITE); display.setTextColor(GxEPD_BLACK); display.setFont(&FreeSansBold24pt7b); display.setCursor(50, 84); display.print(t,1); display.setCursor(50, 145); display.print(h,0); display.print("%"); }

He pedido tres de estos ahora y funcionan muy bien.

I've ordered three of these now and they work great.

Pantalla Ni - No es fácil de programar, pero una vez que usted consigue la caída de ella que son divertidos para experimentar con - El requisito de bajo consumo de energía es una gran ventaja!

Ni display - Not easy to program but once you get the hang of it they are fun to experiment with - The low power requirement is a big plus!
