Measurement
Start the RoKiX Windows GUI software and adjust your settings
as follows to get the device connected:
1.
Select the board configuration from the Board menu:
CY8CKIT-059 / RoKiX adapter A3 / I2C
2.
Select the desired configuration stream for the
corresponding accelerometer sensor from the Stream
menu: e.g.:
KXTJ3 / Accel data 100Hz ±8g high resolution
3.
If the settings are adjusted properly, data streaming should
start automatically, and the on-screen output should
display real time output for X, Y, and Z axes of KXTJ3-1057
sensor.
