User Manual Grid-EYE Evaluation Kit
In the independent mode, data sampling and transfer will be executed by the ATSAMD21
microcontroller ; the program flow diagram is given below:
Flow-chart steps explained:

Decision point - check I
2
C response of Grid-EYE sensor:
o
If valid, Independent mode is confirmed.
o
If invalid, Arduino mode is confirmed.
- Delay of 100ms is applied for periodic inspection of I
2
C. This allows the
microcontroller to determine mode of operation.

Parse the command from PC, such as the command of setting the sampling frequency.

Measurement - read data from the sensor and send it to PC and smartphone.

Updating frequency - if the sampling frequency is updated, then reset it.

Delay applied in the loop, determined by the sampling frequency.
