First question asked
I am trying to get values out of my tlv magnetic sensor

All the read registers(00 to 09) gives 0!!

I know that sensor enters powr down mode at first so there is no value for first few bytes but it should have some values for 07 to 09

Hi @User15938,

 

> Kindly ensure that the circuit is made according to the datasheet (pg#10).

 

> Could you please configure the mode to one of the five below modes and try reading the registers? The reset value for reserved registers is device-specific, so maybe for this device, it is 0, and that's why the three reserved registers give 0.

• Fast mode

• Low-power mode

• Ultra-low-power mode

• Master Controlled Mode (MCM)

• Master controlled low-power mode

 

Thanks,

Ritwick
