we are currently using icp 20100 sensor with i2c communication protocol, but we're not able to read the device id properly it keeps on changing. Is there any important step that i've missed during init or during reading device id?
can anyone please explain the steps for init or tell what's the problem I'm facing.
thanks and regards.

what we do is
1- we unlock master lock register by writing 0x1f to MASTER_LOCK_REG(0xBE) 3 times
2-then we add a dummy read (0x00) i2c instruction
3-we read PRESS_DEVICE_ID_REG (0x0C) and printing the value
but every time it gives different values!
can anyone please help
these are the logic analyser results
Hi,
Did you follow the Datasheet section 6.5 Boot Sequence?
