Resolved! I'm using the STSW-IMG012 "P-NUCLEO-6180A1 pack PC graphical user interface" and a P-NUCLEO-6180A1 pack based on the STM32F401RE. I have tremendous problems setting up values such as "Inter-Meas Period" to 2.5s. The tool is constantly resetting them.

The tool is working (somehow) with a VL6180 soldered to the "Bottom" connector. I want to have a measurement every 2.5s, so I select Device "Bottom, tick "Continual" and enter "2500" for "Inter-Meas Period(ms). When I start the Ranging, the "Inter-Me...

Can we also use SPI to communicate with the VL53L5CX?

Original product brief showed both I2C and SPI peripheral communication available for the VL53L5 but the data sheet now focuses exclusively on I2C. Is SPI then no longer supported or can both/either be used with the appropriate user-provided platform...

VL53L1CX ambient reading and ranging sequences

From what I've read, I get that during a ranging sequence VL53L1CX performs two separate ranging operations and since we have also ambient data I think the sensor listens to the environment without sending any pulses. What I am curious about how they...

VL53L5 GPIO uses?

I have exposed both GPIO1 and GPIO2 pulled up to VDDIO with a 47 K resistor on my VL53L5 breakout. GPIO1 is used as the interrupt. What can I use GPIO2 for, another interrupt? It would be very convenient to have a date ready interrupt on GPIO1 and a ...
