read-range
wayland/vl6180x-time-of-flight/read-range
Read range (mm).
read-range
@/read-range
Read range (mm).
DEV@/vl6180x-device
A VL61080X device.
UPDpulse
Update. Trigger read.
DONEpulse
Pulse on read.
STATbyte
Status. Ranging success/error code:
00h = success; 01h = system error; 05h = system error; 06h = early convergence estimate fail; 07h = no target detected; 08h = ignore threshold check failed; 0Bh = ambient conditions too high; 0Ch = raw range algo underflow; 0Dh = raw range algo overflow;
0Eh = raw range algo underflow; 0Fh = raw range algo overflow.
DISTnumber
Distance (millimetres).
