I did not see anything in the documentation, but for example the sparkfun module for this sensor have a resistor, as I can't communicate with my MPU, was wondering if it may be the problem, as I don't see where it could be if this is not the problem Yes I was generalising, because I worked with an LIS3DH which have both interface, and CS have Pull-up resitor too for I2C operations. But I do agree that this may not apply to all sensor having both interfaces | |
| Sep 27, 2017 at 10:30 | comment | added | DiBosco | I think maybe we're talking about the same thing in different ways. It needs to be tied high or low, but does not necessarily mean directly to GND or Vcc. Sorry, don't wish to appear pedantic. I see nothing about a resistor on CS line. One diagram seems to tie it to Vcc. You can't generalise about how other sensors work BTW. | |

| Sep 27, 2017 at 10:01 | comment | added | DiBosco | Where does it say the SDO pin must be connected to ground for I2C? I don't see this. To me it looks like a pin for setting I2C address. | |
