VL53L3CX Ranging sequence 2.9 Ranging sequence Figure 8. Ranging sequence 2.10 Handshake management
Once a ranging measurement is available, an interrupt is generated. This is communicated to the host as a physical signal on the GPIO1 pin, which is driven low, and the output of a driver function. The former operating method is called “hardware interrupt”, and the latter is referred as “polling mode”. Once the host reads the result, the interrupt is cleared by the driver and the ranging sequence can repeat. If the interrupt is not cleared, the ranging operation inside the VL53L3CX is on hold. The interrupt behavior allows a good synchronization between the VL53L3CX and the host, avoids losing results if the host is not available to acquire or process the data. It is strongly recommended to use the hardware interrupt pin to manage this handshake. For more details please refer to the device driver user manual.
