Hi, I'm hosting a VL53L8CX with a STM32F4, 48-pin instead of the 64-pin on your eval board. There's a 5" flex cable between processor and L8. The vl53l8cx_init() function was failing. Slowing the SPI baud didn't help. Increasing wait time on line 276...

Hello @John E KVAM ,Table 14 in the datasheet shows power consumption in Autonomous as going as low as 4.5 mW, but is this only the AVDD power? or total device power? Because I do measure low power draw at those levels, but only on the AVDD pin (and ...

The eval board for the VL53L5 has a GUI that displays all of the zones. Is there a similar GUI for the 53L8 eval board? I don't see one listed on the Tools and Software tab for the eval board. Or is there a way to make the L5

When VL53L5CX Time-of-Flight sensor is in threshold detect mode, will it trigger only on what would be a Status 5 valid distance? Thanks! -Doug

I'm looking at the I2C spew from a VL53L5C, and it appears to be values for each of 64 zones. Data for a particular zone starts with Z_______ where the blank is the zone number. But instead of starting with Z 0 to Z3F (0 to 64) it goes from ZFFFFFFC ...

My SPI clock looked like the same speed on the scope as it did with your driver. And my SPI config setting look the same (pasted below). And I tried slowing it down by a factor of 8 (SPI_BAUDRATEPRESCALER_256 from _32) without fixing it. Same crystal...

Hello @Anne BIGOT @John E KVAM , I might have stumbled onto the problem. It seems that the device was hung because of a previous pending interrupt, and it wouldn't go into true Autonomous mode until I read the data one more time with vl53l5cx_get_ran...

@Anne BIGOT @John E KVAM Hello Anne or John, We're still hoping to know if a VL53L5CX can operate with the total device power consumption in Table 14 (4.5 mW at 1Hz, 5ms, autonomous), and still be able generate interrupts when objects are detected ...

Exactly! That's why I'm asking the manufacturer! And Table 14 IS the datasheet! And if you read the thread, you will discover that the manufacturer (Anne Bigot) replied to say that Table 14 is total device power. But she hasn't yet quite clarified wh...

@Anne BIGOT Thanks Anne, We're about to throw a lot of dev resources at finding our problem. But before we spend big bucks I'm hoping you can confirm that there is a solution. Can you please confirm that the device really can monitor for objects wi...

VL53L8 api init function didin't work, needed additional delay

VL53L5CX Power Consumption

GUI for the VL53L8A eval board like there is for the VL53L5?

When VL53L5CX Time-of-Flight sensor is in threshold detect mode, will it trigger only on what would be a Status 5 valid range measurement?

Does zone numbering for VL53L5C in 8x8 mode start with ZFFFFFFFC (-4)?
