I2C - Wickfut - 03-01-2024 How do I get access to the I2C bus? I want to add an LCD display. TIA... Wick RE: I2C - admin - 03-02-2024 A8 have a i2c extender interface on PCB, you can use it SDA,SCL connect to your display. such as SSD1306 i2c LCD display. RE: I2C - DaddyLee76 - 03-03-2024 i'm triyng to add a pcf8574T via i2c but the kc868-a8 (I'm using esphome) doesn't see it during the scan. I checked the pcf with an Arduino Uno and everything works properly. with Arduino I at first did a scan to find the right address. then i added the following code on the KC868-a8 #additional pcf8574t - id: 'pcf8574_hub_in_2' # for input channel 9-16 address: 0x27 but I had no result many thanks for your suggestion!
