Resolved! VL53L1: What is the data format of histogram_ranging_gain_factor?

UM2133 says the default value of histogram_ranging_gain_factor should be 0.971. When I get the data for VL53L1_gain_calibration_data_t->histogram_ranging_gain_factor, I get an integer "1987". The data type listed in the typedef in vl53l1_ll_def.h is ...

Resolved! VL53L0X API example for STM32

Hi, I included the VL53L0X API from ST in a STM32G4 STM32CubeMX project. Now I need a example of how to use the API to init the VL53L0X and do a simple range measurement. I'm using the Arduino VL53L0X module.

VL53L1 can measure the target within 8 meters. However, the VL53L1_Gui(api rev 2432 6.6 build 1) showed "NOT VALID" even if the target stood at about 3 meters.

I was evaluating VL53L1 through X-NUCLEO-53L1A2.The GUI (api rev 2432 6.6 build 1) showed NOT VALID, but I checked the Data Log (.csv) and I found the "trueRange_cm" data was valid. I have a question, which data result is true, GUI or Data Log?Thanks...
