Heltec WiFi LoRa 32 V3 Text Display Examples

Heltec WiFi LoRa 32 V3 Text Display Examples.
I am preparing to answer a couple of questions about the Heltec WiFi LoRa 32 V3. So I want to display readings on the OLED display. I have developed this minimal code sketch to demonstrate the fonts sizes, aligning text on the screen and also displaying long strings of text with word wrap.

Thanks for doing the work to get me started in understanding the peculiarities of the board

After many attempts to compile this and other sketches, I finally have success. After installing the newest "Heltec ESP32 Series Dev-boards" version 1.0.0, I'm compiling without errors. This newbie learned a few things along the way, but I did lose some hair in the process.
Good info here, sir! Thank you!

I recently discovered that the VEXT pin isn't necessary for operating the display; it just made the display a little brighter for me. Instead, to turn the display off, I used factory_display.displayOff(), and to turn it back on, I used factory_display.displayOn().

There is also a .sleep() method, after which you need to reinitialize the display. I think the .displayOff() method only turns off the backlight of the OLED, while the .sleep() method turns off the entire display.

Hey boss great video's, I have an idea and i'm having a hard time finding what i need. Context is Meshtastic Messaging. I was curious if i could build a separate Arduino to receive the text on the message screen and convert to morse code audio.

hello, I'm new with lora and codings, what should I do with this error I've got
"Compilation error: HT_SSD1306Wire.h: No such file or directory"

Could you please help me to understand why Heltec V3 LoRa board is not detecting the DS18B20 sensor on the OneWire bus.
the DS18B20 sensor works well with the ESP8266 NodeMCU but not with the Heltec V3 LoRa board

Such a fantastic video, thanks for sharing

Would you please consider doing a video on implementing a node "The Things Network" on the "Heltec WiFi LoRa 32 V3" board?

I've looked, but I've only found one, it is not in English and I could not follow it.

Hello friend, I have had problems with the compilation of my program from Arduino IDE, I have the Heltec LoRa 32 V3 board, I have followed the configuration steps from previous videos and I get the error (Compilation error: LoRaWan_APP.h: No such file or directory). I would appreciate it if you could help me

Where you get HT_SSD1306Wire.h ? My IDE can't to find that header...

[suzyamerica]

Does anyone know if it's possible to add other text displays (such as larger ones) to these Heltec boards? The only one that appears to be set up for it is the Heltec wireless paper .. it has that 24-pin ribbon cable for talking to an e-ink display.

podes hacer un ejemplo de algun sensor, que envie datos y el receptor pueda leer por la pantalla oled?

does anyone know where i can get this Adafruit TFT FeatherWing - 3.5" 480x320 Touchscreen

[shadowwolf]

Happen to know anything about running these boards with micropython?

I Was wondering if someone could provide a link (to a website) -- (I hope there is one) that would have good information (For a Super Noobie like me) to learn how to progam one of these LoRa Devices..

[JudyFayLondon]

Yeah, it seems so, we can only get so many lines on the screen.
