I connect a vl53l1x-satel to a stm32wb55rg6 with 4 essantial pins (sda, sdl, gnd, vdd). I have a problem to wait for a result. With de function VL53L1_WaitMeasurementDataReady() i haven't problems but for my project I must not use a blocking function...
Hello,I have following issue.For distance 0 mm - 60 mm the result of range measurement is always the same (0x20)step by step code:GPIO0 set High.Range measurement start: write 1 to reg 0x0018Wait 100msRead range status: read register 0x004DRead range...
Hi everyone,I was wondering if it is possible to supply my VL53L0X with a 3V3 voltage?According to the datasheet, the 3V3 respects the recommanded operating condition.But when I look for example board from ST or other vendors, there is always a conve...
I have rewritten the C app for the VL531 in LAIRD SmartBasic in order to drive the VL531 from a BT module (BL652). I communicate OK with the VL531 over I2C but when I sent the start command (and after I get a Data Ready from register 0x31 as shown be...
Hello Guys,I hope you all are doing well.I am working on a project that with the VL53L0X ToF Sensor and ESP modules.The sensor works great and i am trying to get deeper into its reads because what i need.I am trying to build a frequency meter using t...
Hi,the laser works at 940nm. Do we know whether the SPADs are tuned to this wavelength, or whether they would also be able to detect photons at other wavelengths (double the original wavelength, for instance) ?Thanks a lot in advance
Hi. I'm working with the STM8TL52F4 MCU and its touch/proximity sensing peripheral. I made a simple touchkey sensor simulating Fig 3 AN4313 (ST App Note: Guidelines for designing touch sensing applications with projected sensors). If the sensor is to...
In my setup I have VL531LX proximity sesor connected as per datasheet. Every time when I call startMeasurement interrupt is risen immediately after (often two interrupts). By user manual UM2356, figure 3. this clearly should not happen. I was wonder...
Gentlemen! Sorry for bothering you.I try to use VL53L1 with the Light Driver. The power level is 3.0 V, so I changed the Initialization data array, cell 0x2E from 0x00 to 0x01 and cell 0x2F from 0x00 to 0x01. I wait for the Device ready (SensorState ...
