### 3. max30102
28+
29+
#### 3.1 command Instruction
30+
31+
​ max30102 is a basic command which can test all max30102 driver function:
32+
33+
​ -i show max30102 chip and driver information.
34+
35+
​ -h show max30102 help.
36+
37+
​ -p show max30102 pin connections of the current board.
38+
39+
​ -t (reg | fifo <times>)
40+
41+
​ -t reg run max30102 register test.
42+
43+
​ -t fifo <times> run max30102 fifo test. times means test times.
44+
45+
​ -c fifo <times> run max30102 fifo function. times means read times.
