Hey guys! Can anyone tell me how I can use the ESP32 WROOM with an OLED I2C 128x64 display to show mining data?

Hi

That's easy, I have set this up here with VSCode & Platformio: https://github.com/paelzer/NerdMiner_v2_paelzer

Display I2C pins: SCL - ESP32 GPIO 22 SDA - ESP32 GPIO 21

Import the code into Platformio and select the env "ESP32_SSD1306". Then compile and flash your board.

Should look like this:

Would be nice to know if it worked for you.

Sounds good. I will do some improvements next days and ask them to add it to the official NerdMiner_v2 repository.

This is great! Thanks! Is it possible to update it to V2 to get up to 75khs? Currently getting 55khs on this code.

[paelzer]

You need an S3 to get 75 kh/s. Not sure if an S2 is also capable, I don't have one so I can't test, but with a usual ESP32 it won't go over 58 something.

This one I tested, works fine at 78

OH! That makes sense. Thanks for making that clear, I am learning.

@paelzer Thanks for sharing... works with ESP32-S3 DevKitC-1 - only added other pins as build args
