 Instructable..
<p>display.drawExampleBitmap(gImage_splash, 0, 0, 200, 200, GxEPD_BLACK);<br>display.update(); delay(3000);</p>
Then we display another bitmap which is the main GUI of the project.
<p>display.drawExampleBitmap(gImage_gui, 0, 0, 200, 200, GxEPD_BLACK);<br>display.update();</p><p>display.drawExampleBitmap(gImage_gui, sizeof(gImage_gui), GxEPD::bm_default | GxEPD::bm_partial_update);</p>() {<br> sensors.requestTemperatures(); tempC = sensors.getTempCByIndex(0); showPartialUpdate(tempC); printTemperatureToSerial(); delay(5000); }</p>

Question 7 months ago on Step 4
Hello, im new here and want to use the epaper demo on a ESP32 Pico Kit V2 and V4. I have trouble to display the content on the epaper. Im sure i use the wrong SPI pins. Can someone give me a hint please? Thanks a lot in advance!
Question 9 months ago on Step 4
Well done. A very nice starter project.
Q1 Calibration. I have trouble with various digital thermemeters reding differently in the same water. How do you calibrate the DSB18B20 Sensor or does it come accurately calibrated?
Q2 How does your ESP32 compare with the Rasberry Pi?
Q3 I have a boat that needs a depth sensor. Do you know of any such projects preferably with WiFi connection.
It would be good to have a tick box here to send a copy of my queries to my email address.

Hello there.
I make this nice little thermometer to install it in my RV: I'll post images when the final setup will done...
I would like to have the word "Temperature" in my mother language, Italian, so "Temperatura", with the "a" at the end: how can I do that?
Thanx in advance,
Stefano

Hello Stefano, you have to create a bitmap file with the word Temperatura as the background of the display and then load it as I do it.

Done but, as expected, I lost other items...
It would be very useful if the Image2LCD utility was reversible, but not...

Not too bad, anyway...
Unfortunately we can't increase font size.

Mani thanx!
This is the very last release, ready to be permanently installed on my VW RV.
I'll do another one with outside temp, too.
I add the bmp also if anyone wish to do the same, but we have to change the position of the temperature "windows":
uint16_t box_x = 55;
uint16_t box_y = 55;
uint16_t box_w = 90;
uint16_t box_h = 85;
uint16_t cursor_y = box_y + 16;

Great Tutorial, but one question please, where do you get the fritzing part for the waveshare e-ink Display from?
Answer 11 months ago
I just used a display that already existed in Fritzing and modified it in photoshop afterwards.

Awesome Instructable! I wasn't familar with e-paper displays before this and am now thinking they'll find a way into my next project. How long does that power bank last you?
