Posted on March 19, 2015 at 19:38I am betting that the LIS3DSH is like the LIS3DH and that the I2C address select pin has an internal Pull Up resistor. Since you are grounding that pin you have an extra current flowing through that pin. We confirm...
Posted on March 19, 2015 at 19:32From the datasheet:Self-test allows to check the sensor functionality without moving it. The self-test function isoff when the self-test bit (ST) is programmed to ‘0‘. When the self-test bit is programmed to‘1â...
Posted on March 19, 2015 at 19:27We encountered the same problem with the LIS3DH. The SA0 has an internal pull up. If you ground it you will draw the extra current. We float it to set that address bit = 1 on the I2C bus.
