Resolved! [VL53L8CH] Switch between different ranging modes
Dear ST,The VL53L8CH's example codes have demonstrated how the sensor can be controlled through set of APIs. However I am still not very sure about how can I switch between different working modes on-the-fly during runtime.For example, assume I have ...
Issue with cup detect GUI for P-NUCLEO-53L8A1 evaluation kit.
Good morning. I am trying to evaluate a P-NUCLEO-53L8A1 evaluation kit. I downloaded the software example from your website and unzipped it. I then attached the eval board to a USB port on my laptop (running Win 11). It enumerates as a STLink VCP. ...
Resolved! Ambient light level with vl53l8cx ?
Hello Everyone ! I would like to know if it is possible to measure ambient light levels either directly or indirectly , using the VL53L8CX sensor. Thank you in advance
VL53L7CX blinded by retroreflective surface
I'm using several VL53L7CX sensors in a robotics application. They work well except for when a retroreflective surface is present, which blinds the entire sensor, including SPADs not pointed at the retroreflective surface. A large retroreflective a...

Resolved! Register Map for VL53L8CX
I am trying to use VL53L8CX with stm32f4 discovery but had no success. Implementing the preexisitting API has been tough. Is there a register map for this sensor whcih can be used to create a minimalistic driver and interface sensor using I2C or SP...
Resolved! External Trigger
Dear altruist, I need urgent help. Can I apply hardware-based external triggering in the VL53L8CX sensor by STM32 Nucleo F401RE? Will the sensor work for external triggering? Thank you
STM32N657B0 Drive the VD55G0
I want to use N657B0 to drive VD55G0, and the camera side can already enter the Stream state. After I use the function HAL_DCMIPP_CSI_PIPE_Start, I track the variable csi_instance through single-step debugging and find that several bits in its SR1 re...
