I am trying to use the BMM150 with a higher ODR but I am not able to do it. I have some questions I would need help with. First. Do I need to set FORCE mode right before a reading? I am finding that in case I do not do that, measure is not refreshed. Second. I have read on the manual that in order to get ODR > 300Hz I should use LOW POWER PRESET with Rep XY 3 and Rep Z 3. Recommended ODR is 10 but then I should use FORCE MODE. This is the configuration I use: REP XY register should be 1 because the formula says that (RepXY = Register value * 2 +1) REP Z register should be 2. As manual says, REPZ = Register value + 1. On the 0x4E register I configure the following: |DRDY Enable|INT disable|CZ enable|CY Enable|CX Enable|DR Pol High|ILatch NO|IPOL High| This gives me a register of 0x85 On register 0x4C I configure the following: |ADVST NORMAL|ODR 10|OPMODE NORMAL|ST DIS| This gives me a register of 0x00 Then, every time I want to read I send the 0x4C register to be set as FORCE (register 0x4C set to 0x02) and then I performe a read of 8 values on the 0x42 address. I do not see improvements of doing this instead of checking the DRDY bit status and then perform a reading. Is there something else I need to do? Is there anything wrong on the configuration? Thank you!
