WebbWhen you are going to use I2C modules for your Arduino Projects, sometimes the manufacturer didn't give the address of I2C device inside the chip. It can be a serious problem if the address is unknown or you write the wrong address. This method is used for scanning the I2C Device inside your module that connected to I2C bus in Arduino … Webb5 jan. 2024 · 1. The OLA detects a device on address 0x61 (that means SDA and SCL are working). 2. The next step is to check whether a device with address 0x61 is known to the OLA code. 3. If so do a begin() to see whether the sensor response to initialize. If that fails it will assume it is NOT that known sensor. I expect however that begin() will work. 4.
