I'd leave it and then that gives two opportunities to find it. Will try your code as reading standard fonts on these OLEDs is difficult.
Should be readable at 4x scale ;)

Done, do you want me to remove the previous post's content and just put a link to the solution on GitHub?

Re: Larger fonts on SSD1306 OLED displays

If someone is still interested in this topic, here is a solution I came up with.... NB: I am using ESP32-WROOM-32, 0.91" OLED 128x32 from machine import SoftI2C, Pin import time import ssd1306 OLED_SCL_PIN = 22 # clock OLED_SDA_PIN = 21 # data OLED_WIDTH = 128 # pixels OLED_HEIGHT = 32 # pixels def ...

BLE HiD Keyboard on Windows 10

Does anyone have a working solution for BLE HiD Keyboard on Windows 10.

I could not make the WIP one to work:
https://github.com/micropython/micropython/pull/6559

I would like to send just a simple character and see it written in some editor.

Thank you!

Re: Cannot find I2C devices on ESP32

This simplifies things, I just used 4.3K Ohm resistors and can confirm that everything works fine.

Thanks again!

Re: Cannot find I2C devices on ESP32

Thank you Roberthh!
Your pullup idea did the trick:

NB: I didn't have 4.7k so I had to use 10k and 9.1k in parallel which gave me 4764 Ohm.

Re: Cannot find I2C devices on ESP32

Please find wiring attached:

One can see that the green wire is SDA.

NB: I did try to switch the wires on esp32 and got the same result

Cannot find I2C devices on ESP32

Hello, I am trying to make a display (128x32 I2C Pi OLED) to work with esp32 (ESP - WROOM-32) OLED device is working properly as I have tested it with Arduino using Adafruit's libraries. Esp32 device is working properly as it runs other code without problem. I followed a video [https://www.youtube.c...
