Arduino Uno made by Elegoo
I wired it up based on the instructions on p23 of the Adafruit eInk Display Breakouts and FeatherWings guide
I'm using Arduino IDE 1.8.16
I installed the required libraries.
I ran EPDTest.ino w/ the following modification since the datasheet on the eInk display product sheet shows the text "IL0373" on page 5
Code: Select all
//Uncomment the following line if you are using 2.13" EPD with IL0373
Adafruit_IL0373 display(212, 104, EPD_DC, EPD_RESET, EPD_CS, SRAM_CS, EPD_BUSY);
#define FLEXIBLE_213
Also worth noting:
- I probed a few of the lines for signs of life and I do see SPI-ish looking signals on SCK and MOSI.
- At certain points in my tinkering the display actually did update, but not in a controlled way (display would either get cloudy or clear). I don't remember what exact conditions made this happen. I *think* one of the signs of life came when I hit the reset button on the dev board.
- 3V3 pin is giving me 3.3V, which is evidence that board isn't burned
