Using the VL6180X sensor with default initial configuration found in the documentation (chapter 2.1), the measurement task remains stuck waiting for the measurement bit to be set on the 0x4F register (measurement ready).The bit seems to never be set.
Hi!I have an automation project that requires a large number of sensors (up to 30). All sensors have digital outputs and use the I2C communication protocol. I would like to know if it is possible to have all the sensors sharing the same I2C bus. If s...
I think those two values are for HDR(High Dynamic Range). Am I right?1. If so, is it possible to use the same value for VL53L0X_VCSEL_PERIOD_PRE_RANGE and VL53L0X_VCSEL_PERIOD_FINAL_RANGE?The amplitude(brightness) of the reflective sheet gradually l...
I have a simple ranging project generated by CubeMX using X-Cube-TOF1 v2.0.0. The host is Nucleo-L452.Initialization of the VL53L2CX appears to work without errors, however when the "VL53LX_run_device_test" function runs it fails after the timeout, r...
In vl53l5cx_init, the sensor sends the `VL53L5CX_FIRMWARE` data to the sensor. This means the main application MCU needs to store the ~80kB+ in its data. Can this be modified so the firmware is downloaded only a single time, so there is less memory o...
Hi, I am trying to use the vl53l5cx_set_i2c_address() function in order to change the i2c address, but it keeps returning -2, or VL53L5CX_COMMS_ERROR from the following line in vl53l5cx_set_i2c_address(): status |= WrByte(&(p_dev->platform), 0x7fff, ...
Hi, because there is almost no information about Motion Indicator from the existing docus, could you pls explain how does it work. And what does it aim to be used?Thanks,Best regards,Wayne
Hello,I want to evaluate VL53L3 / VL53L5 devices. The end application will be behind glass with a distance of ~20-30mm between sensor and glass. I've Nucleo and Satellite boards for the two sensor types and setup a corresponding test environment wher...
Hi,we are planning to use 3x VL6180 on same PCB to accurately (1mm) measure distances in a dark container. Our required range of measurement is 2 to 80mm. So far we got to around 0.5mm accuracy, but the problem is repeatability. Exactly what i mean i...
I have a design ready to go but it needs to work for 3 years using 4xAA alkaline batteries. My company has planned 500K pcs/yr. I would really appreciate any help with this.Thanks,AL
