Data Sheet

[14] bit 3 for Offset Cal flag. Set means “custom” else “default” settings
being used currently by tinyLiDAR.
[14] bits 2 and 1 for LED Indicator mode.
• 00 means ‘OFF’.
• 01 means ‘ON’.
• 10 means ‘Measurement’ mode.
[14] bit 0 for WatchDog Timer flag. Set means “ON” else “OFF”.
[15][16][17][18] for Offset Cal value. Scale down by 1000 for proper value
in mm.
[19][20][21][22] for Crosstalk Cal value. Scale down by 65536 for proper
value in MCPS.
Example:
Query tinyLiDAR connected at the default address of 0x10.
For this example, we have
0x53 = SingleStep mode
0x54 = tinyLiDAR
preset
0x1999 = Signal Limit read as 6553 so that is 6553/65536 = 0.1 MCPS
0x3c = Sigma Limit is 60mm
0x0012 = Timing Budget which is 18ms
0x12 = Pre Range VCSEL Period of 18 and so Final Range VCSEL Period =
14
0x01 0x03 0x07 = tinyLiDAR f/w version 1.3.7
0x01 0x00 0x02 = ST PAL API version = 1.0.2
0x05 = 0101 so this means “default” offset cal being used,
Measurement mode for LED setting, and WDT is ON.
0x00 0x00 0xcF 0x08 = 53000 so that is 53000/1000 = 53mm offset
0x00 0x00 0x00 0x00 = 0 for the Crosstalk cal.
