PSoC™ 4

[urchc_1533771]

I want to make fitness device that can control CADENCE, Rotation of pelvis and Side to side drop of pelvis.

Can you suggest sensors chips and how to connect to PSOC ?

[Bob_Marlowe · Accepted solution]

You will need an IMU device sensing acceleration and rotation. Typical interface is I2C which you connect with two wires to your PSoC.

Devices similar to

MPU9255 (3-Axis Acceleration + Gyroscope + Magnetometer 9-DOF IMU)

Rotation I can get by gyroscope but how to get running speed ( cadence) ?

[Bob_Marlowe]

Velocity is the integral of the acceleration. Cadence can be filtered from z-axis movements.

Will require some amount of math.
