WORK MODE

1.

Initialization and Power-saving mode

Initialization:

It starts as soon as being powered on. After 200ms delay, the module will

enter into sleep mode.

sensor module then can accept other commands.

Sleep mode:

The DSPC01 module will enter into sleep mode after getting command

(0x71) from the host.

2.

Altitude Mode

The host sends command (0xA0) to DSPC01 and the module will return 3 bytes of Hex data

representing altitude value. The MSB of first byte is symbol bit so the altitude might be a

negative number. The remaining 23 bits will be divided by 10 and the result is the actual

altitude in meters.

E.g. 0x80 00 10 = 1 00000000000000000010000B  -1.6m

0x00 07 D1 =0 00000000000011111010001B  200.1m
