I2C Frequency in boneIO ESP

Warnings¶

Hi, the latest Esphome moved logs about slow OLED response from debug to warning. You’d see:

Components should block for at most 20-30ms

In order to get display response faster we need to speed up I2C bus. So please change your I2C config (frequency changed from 100kHz to 400kHz).

New I2C config.¶

i2c:
  - id: bus_a
    sda: GPIO14
    scl: GPIO15
    scan: True
    frequency: 400kHz
  - id: bus_b
    sda: GPIO17
    scl: GPIO33
    scan: True
    frequency: 400kHz

Changes are already present in our github repository with Esphome config.

Just remember to choose branch based on your board version.
