Hi, I ran into a weird issue initializing a VL53L8CX over SPI where the firmware was seemingly failing to load correctly (the firmware checksum was wrong, and trying to read back some of the firmware from the sensor showed that it didn't match the da...

I'm looking into using the VL53L7CX on a board designed for the VL53L5CX. I expected it to be a drop-in replacement on the hardware side with only a change in software needed (using the L7CX API instead of the L5CX API), but when I compared the two A...

I'm testing the VL53L5CX and finding that the behavior of the LPn pin differs from what is described in the datasheet. The datasheet says "Drive this pin to logic 0 to disable the I2C comms when the device is in LP mode. Drive this pin to logic 1 to ...

I haven't been able to find a recommended footprint (PCB pad layout) for the VL53L5CX, either in the datasheet or anywhere else. When will that be available? Or did I miss it somewhere?

Hi, do you have an update on whether there is a solution or workaround to allow a slower SPI frequency to work?

It seems like you should be able to just insert a line to call the function like this, immediately after vl53l7cx_init(): printf("Sensor initializing, please wait few seconds\n"); status = vl53l7cx_init(&Dev); status = vl53l7cx_set_resolution(&Dev,...

Have you looked at Example_2_get_set_params.c from the API? That example sets the resolution to 8x8.

Hello, Alex.Thanks for your reply. I'm not seeing that function in the ULD (VL53L5CX_ULD_driver_1.3.9); is there a different API that you're talking about?I do see a function vl53l5cx_is_alive() that checks for device_id and revision_id of 0xF0 and 0...
