Hello,

I am not sure of the issue. Could you share your whole file? I will go through it. There is a developer academy course on I2C communication; please make sure you have followed every step mentioned. As an example, you can go through the exercise section.

Kind Regards,

hello,

Yes I used CONFIG_VL53L1X in my prj already.

and I use this 0x29 address in overlay to make i2c communication ,

both address 0x52 and 0x29 show (sensor: device not ready.)

Hello,

Could you try enabling the configuration CONFIG_VL53L1X inside the prj.config?

The address 0x52 is an 8-bit address, and when converted to a 7-bit address (used on the I2C bus during communication), it becomes 0x29. This is done by right-shifting the address by one bit

(0x52 >> 1 = 0x29). This is why you're seeing 0x29 when you use an I2C scanner or a logic analyzer, and why you need to use 0x29 in your code.

I had use address for this sensor is 0x29 , while in the given address in the dataseat is 0x52, Here is the reason for this , when i use the 0x52 address and use logic analyser its show nothing, and when i used 0x29 its show the graph . after that I used i2c scanner on arduino for this sensor the result was also 0x29, thats why I am using this address.

Hello,

In the overlay you provided, the device address for the vl53l0x sensor is set to 0x29.

Please make sure that the device address specified in your code matches this address. If your sensor has a different address, you will need to update it.

The device not ready message can be because of a connection issue or the sensor not being powered properly.
