forked from hkoffer https://github.com/hkoffer/M5Stack-Thermal-Camera-
Latest revision: 20180626
What differ from the original repo
- Code refactoring (pretty much everything)
- UX revamped
- Display the min value
- Display FPS
- Autoscaling temperature
- Move the spot value (in float) to the center
- Pin point the min and max pixel (min colored in blue and max in white)
- Auto reboot and reset the i2c port in case of bad connexion
- Pause state
- Autosleep function
Onboarding
Required library
Settings
Please change the settings in the file M5Stack/M5Stack.ino if something is wrong (especially the orientation).
| Setting | Default | |
|---|---|---|
ORIENTATION |
1 | Set the orientation of the screen Some batch of M5Stack need it 1 while some other need 0 |
BRIGHTNESS |
255 | Brightness level from 0 to 255 |
SLEEP |
5 | Time in minutes before auto turn off |
DEFAULT_MIN |
22 | Minimal temperature scale at boot |
DEFAULT_MAX |
32 | Maximal temperature scale at boot |
Usage
If no buttons is used after the set period (5mins by default) the unit will power off automatically.
| Mode | Button | Function |
|---|---|---|
| MODE | B | Autoscaling (take current min/max) |
| C | Pause the screen | |
| SMIN | B | Reduce the minimal temp of the scale |
| C | Increase the minimal temp of the scale | |
| SMAX | B | Reduce the maximal temp of the scale |
| C | Increase the maximal temp of the scale | |
| POINT | B | Activate/Deactivate the pinpoint of the minimal reading |
| C | Activate/Deactivate the pinpoint of the maximal reading |
When in frozen state:
| Button | Function |
|---|---|
| A | Turn OFF the camera (Also turn back ON) |
| B | Nothing |
| C | Unfreeze the camera |
Might do (eventually)
- Save to SD (maybe save the buffer as bmp then display it and let the choice to save when on frozen state)
- Add sensor reading as overlay with low alpha over a real camera feed (need to compensate the angle)
- Web interface (yes, it's useless but I like remote control of crap)
- API REST of the raw values (because why not)
