Here it is. |
| Lagros:
Try unsoldering R10 and R11 and turn it on without these resistors. |

| Lagros:
Pull-up resistors are present in OLED. Try it! |

I installed STM32 Cube and tried to change the I2C mode from FastModePlus to FastMode but I can’t figure out how to do that. :palm: Moreover, the project doesn’t seem to be the latest one. I guess I’m :horse: --- End quote --- Miti, this is not enough. It is also necessary to change the frequencies inside the microcontroller buses The pull-up resistors for the I2C bus and 3.3V voltage are not selected correctly. They should be equal to 1k. You can calculate this using an online calculator. |
