Imaging (sensors)

Very unstable operation of the VL53L0X sensor. It can output 8191/8190 on the first run and output correct values on the second. Please any suggestions how to solve the problem?

Hello. I have problems with VL53L0X sensor. I will list my observations here.First, I carry out the calibration procedure. The sensor passes all initialization steps correctly (Data Init(), Static Init() and so on). Then calibration is performed. For...

histograms with two peaks when detecting a single target

We are using VL53L3CX evaluation board to dig out some information from the histogram.The 24-bin histogram are retreived by calling the Get_AdditionalData function. Two consecutive sets of histograms are got, when we use a white wall as target and th...

VL53L5CX API Size "vl53l5cx_buffers.h" seems to be too large for the MCU to handle. Is splitting the buffers ( "VL53L5CX_FIRMWARE[]" )into smaller 'chunks' to send to the SPAD a reasonable solution?

I am trying to use the VL53L5CX with an AVR128DB48. The .h file "vl53l5cx_buffers.h" seems to be too large for the MCU to handle. I think, as it stands, it breaks the 32727 byte limit that AVR is capable of. Is splitting "VL53L5CX_FIRMWARE[]" into sm...

"Static object Removal" concept possible on latest VL5xx sensors?

ST,Another non-IR sensor we have worked with has something called 'static object removal' in its microcode. When this function is turned on for a given range, it internally histograms the environment so that objects within this range 'get deleted fro...

Increasing max FOV angle of latest VL5xxx sensors?

Enjoyed your nice presentation...We need almost hemispherical coverage (maybe 160+ degrees etc) for intrusion/prox detection;we are not power sensitive.Are there optical ways of increasing FOV of the latest 60+ degree FOV sensor to well beyond this F...

On the vl5VL53L5cx, the vl3l5cx_check_data_ready function,

 the expected results on the temp_buffer are: if((p_dev->temp_buffer[0] != p_dev->streamcount)            && (p_dev->temp_buffer[0] != (uint8_t)255)            && (p_dev->temp_buffer[1] == (uint8_t)0x5)            && ((p_dev->temp_buffer[2] & (uint8_...

I designed my own vl53l1x board shape that fits my application, but it does not work

first i test the code with the black board and I read data normally,I designed my round board by reverse engineering of the black board,I test my round board with the same code, but I got an error as shownin the attached picturesif any one can help p...
