Question

Daisy chain multiple VL53l1X - lack of information about GPIO1

Hello,

due to the bad datasheet and missing register map it is almost impossible to get information about GPIO1. The only settings i found are affecting the interrupt functionality. But why is the pin called GPIO when only used as interrupt output. Shouldn't it be called INT? Is it possible to use it to daisy chain multiple sensors? Sensor 1 GPIO1 => Sensor 2 XShut, Sensor 2 GPIO => Sensor 3 Xshut...

Thanks, Manuel

Hello,

It is called indeed GPIO by the HW but used as an INT by the FW. So, you can not daisy chain multiple sensors. Sorry about that,

Anne

Hi Anne,

thanks for you reply.

But didn't your engineers thougth about using multiple sensors?

It could be so easy with a daisy chain.

Enable first sensor, set address, enable next sensor, set address...

Only 5 wires would be used for all sensors.

Best regards
