I am trying to perform the XTALK calibration for my system that includes a coverglass on top of the sensor. I am not exactly sure what the point of calibration should be. I've read in the forum: "When doing crosstalk calibration you need to find a ta...

I am trying to get consecutive measurements from the VL53L1X sensor but the timing budget is only kept on the first measurement with the below codeVL53L1X_BootState(dev, &sensorState); VL53L1X_SensorInit(dev); VL53L1X_SetDistanceMode(dev, 2); VL53L1X...

Hi,I am trying to interface an OV7670 camera module with the F746 NUCLEO board and was wondering if the f746 chip's DMA has only a specific memory area where it works.The image resolution will be QCIF so buffer has to be 50688 byte long.thanks

Hi,I know there are plenty of similar topics on here but most are unresolved and when they are resolved the OP never posts about it.So I am creating code through STM32CubeIDE for DCMI with DMA (with help from here).I'm using the NUCLEO board.The OV76...

One more thing, I haven't performed RefSPAD calibration. The datasheet says this should be done for cover glass applications.The VL53L1X ULD driver that I am using doesn't have this function however. Is that included in the VL53L1X_CalibrateXtalk fun...

I've tried with budget 200ms and inter measurement of 500ms with the same results.Ok I guess I'll have to try and search for a bug in my code somewhere then and the Start Stop method works fine. thanks

When the Start command is given the VCSEL flashes once and the interrupt line goes high.Then when I clear the interrupt the interrupt line goes low and never high again.If I use the Start-Stop technique for a single measurement and clear the interrup...

Right, got it.I tried also from a lower actual distance of 410mm and measured 365mm (11% error) and got 5277. After this calibration however, the sensor is over ranging after about the 750mm mark. This over ranging is present when I just try to range...

I went ahead and spray painted some cardboard. I am indeed seeing the deviation at a much shorter distance of 778mm (actual) and 609mm measured.At that point I calibrated XTALK which gave a result of 4890.I then set that value with VL53L1X_SetXtalk.H...
