IR allsky-camera project using 5 sensors MLX90640
|
|
=================================================
|
|
|
|
When attached, udev will create symlink /dev/ir-allsky0. This is the udev rule:
|
|
|
|
```
|
|
|
|
ACTION=="add", ENV{USB_IDS}=="0483:5740", ATTRS{interface}=="?*", PROGRAM="/bin/bash -c \"ls /dev | grep $attr{interface} | wc -l \"", SYMLINK+="$attr{interface}%c", MODE="0666", GROUP="tty"
|
|
|
|
```
|
|
|
|
Protocol:
|
|
|
|
```
|
|
|
|
dn - draw nth image in ASCII
|
|
gn - get nth image 'as is' - float array of 768x4 bytes
|
|
l - list active sensors IDs
|
|
mn - show temperature map of nth image
|
|
tn - show nth image aquisition time
|
|
B - reinit BME280
|
|
E - get environment parameters (temperature etc)
|
|
G - get MLX state
|
|
R - reset device
|
|
T - print current Tms
|
|
Debugging options:
|
|
aa - change I2C address to a (a should be non-shifted value!!!)
|
|
c - continue MLX
|
|
i0..4 - setup I2C with speed 10k, 100k, 400k, 1M or 2M (experimental!)
|
|
p - pause MLX
|
|
s - stop MLX (and start from zero @ 'c')
|
|
C - "cartoon" mode on/off (show each new image) - USB only!!!
|
|
Dn - dump MLX parameters for sensor number n
|
|
Ia addr [n] - set device address for interactive work or (with n) change address of n'th sensor
|
|
Ir reg n - read n words from 16-bit register
|
|
Iw words - send words (hex/dec/oct/bin) to I2C
|
|
Is - scan I2C bus
|
|
Us - send string 's' to other interface
|
|
|
|
|
|
```
|
|
|
|
To call this help just print '?', 'h' or 'H' in terminal.
