Thanks for your reply, a few followup question: 1. could you say a little bit more about why a pressure sensor is needed in addition to an accelerometer+gyro for this project. 2. I was wondering if you could share whether its possible to configure the registers in a BMA400 to detect any activity other than walking ? Like rope skipping, or doing lunges, squats etc. ? I was hoping that that the registers can be configured to make the BMA400 detect some closely related activity as well by just making a few small changes. I am okay with experimenting and doing trial and error to fine tune new register values but that will need some understanding of what each register does. Thanks

Hi, I am trying to use the BMA400 to detect the swings of a tennis racket. And I was wondering if its possible to simply configure the registers (0x59 to 0x70) that are used for step-counting and set them in a way to detect this activity instead. Right now in the datasheet (bst-bma400-ds000.pdf) the settings for these registers are mysterious. I was wondering is there a description of exactly what the meaning of each of these registers is? Basically I want to go from a sample acceleration waveform to a corresponding setting of STEP_COUNTER_CONFIGX that will let me detect that waveform. Is that possible? Or must I implement alternative activity detections in software.
