I use an arduino UNO rev3 and a grove Base Shield V1.3 for my project.
I want to use the I2C bus to with the OLED 128*64 display and the 3 - axis accelerometer together but only the OLED display work and not the accelerometer…
If I use only OLED display it’s work great and it’s work great too with only the accelerometer, but not together.
I try to put pull up resistors (1k, 1.5k, 1.8k, 2.2k, 4.7k, 10k) between SDA (pin A4) - 5V and SCL (pin A5) - 5V but no result.
The adresses are not the same (OLED 0x3c, accelerometer 0x53, digital light 0x29).
So what’s the problem ??
