Command format
The structure of the command sent by the application is almost identical to the structure of the answer from
the MLX90130, as shown below:
Command:
[CMD] + [LEN] + [DATA]
Answer:
[RESPCODE] + [LEN] + [DATA]
-
[CMD] = Command (
1byte
)
-
[LEN] = Length including only the field DATA, zero if no data sent (
1byte
)
-
[RESPCODE] = Response code, depends on the command (
1byte
)
-
[DATA] = Data information, depends on the command (
0 to 528bytes
)
