VL53L9 software package for low resource microcontroler ?

Hi,

 

I’m trying to use a VL53L9 with a microcontroller which have 128kB of RAM. For this I use the STM32CubeExpansion_53L9A1_V1.0.0 package. 

The problem is the streaming library delivered within the package is not made for low RAM usage. It’s stack usage is high. Too high for the microcontroller I use.

Is there VL53L9 software implementation available for low RAM usage ?

 

Regards,

Nicolas

Hello ​@DrPiWork,

We do not have a specific software package for low-resource microcontrollers. However, some functions can be disabled, such as the TNR and sharpening algorithms, and the resolution can be reduced by using binning.

Thanks, Megane

Hello ​@MeganeG ,

 

Thanks for your answer.

Can I completely avoid the usage of the streaming library (it is not clear to me what it is used for) ?

 

Best regards,
Nicolas
