Multiple LIS3DSH sensor read on same I2C port with diffterent address , 1D,1E is possible

[chaitanya chippada]

Hi ,

for my new project, we placed two LIS3DSH vibration sensor on one small PCB,and we need to acquire both sensor data simultaneously with different address on same I2C port,

Can you give any idea about how to manage two Lis3DSH data aquation on same I2C channel simultaneously ???

SEL (Pin 7] defines the I2C address, so you can have two devices on the same bus.

SEL = 0 ... I2C address is 0x1E (7bit)

SEL = 1 ... I2C address is 0x1D (7bit)

You cant read the data simultaneously on one bus, you have to alternate between the two sensors.
