Request of VL53L0X

Hello,

I am using VL53L0X to perform range measurement. I knew there are C APIs and examples that provided by ST already. However, due to I am developing my project by other language, I think I should access to registers to achieving measurement.

My problem is I don't know the definition and valid value of all registers. I tried to find relevant information on my.st.com and some technical forums, and got some useful clues. For example, I knew the address of VL53L0X_REG_SYSRANGE_START is 0x00 and I can configure different modes of range measurement by setting different values. Sadly, I cannot find a Spec that guides me to learn whole registers. So I will not achieve more functionalities by reading/writing registers.

So could you please provide me some relevant information or Spec which describes all registers in VL53L0X ?

Thanks!

Hi

oliverbeirne

‌

Thanks for your help!

I downloaded the 'VL53L0X_1.0.2' and found the 'vl53l0x_tuning.h' in VL53L0X_1.0.2\Api\core\inc. However, there is no comments for those register configurations. It seems to me very confused what's the meaning of those registers and why I need to perform so many configurations.

Im not from ST but I have had the same problem since the start of 2017. What they have told me / my contact in Avnet is:

'

Memory map and register content is not provided for this device because it is too complex to understand the registers content. Today, the only access to the device is API, and could be also scripts in medium term.

' I got this answer less than a month ago.

I guess this answer your question?

'

Memory map and register content is not provided for this device because it is too complex to understand the registers content. 

So basically ST is saying that all EE's and CE's are incompetent.

They'll lose a lot of sales because of their stance on withholding info about their device.
