Simply device to help work with LEDs.
Project described: note PL, video PL
If any of my projects have helped you in your work, studies, or simply made your day better, please consider supporting my work. LINK
The device in the plan has 3 operating modes:
- WS2812 color picker
- PWM generator for simply LED
- Change of PWM in time characteristics
The modes can be changed with buttons on top pic 1.
- WS2812 color picker
- PWM generator for simply LED
- Change of PWM in time characteristics
Every mode has different handling reactions from joystick (1. on pic 2.) control.
The device can control the intensity of red, green and blue colors on a scale from 0 to 255.
To do this, use the joystick: up / down to select a color; right / left to increase / decrease the color saturation value
The device can control the intensity LED light with PWM.
To do this, use the joystick: up / down to change duty.
The device can control the intensity LED light with PWM in time or manual based on mathematical function (pic 2.). To do this, use the joystick: up / down to select mathematical function; right / left to change input to mathematical function; center to run mathematical function from 0 to max PWM value.
The code is prepared for Wio Terminal. About platform: video.
WS2812 data pin is connected to BCM27. LED connected to BCM23.
The project is prepared for the Platform IO environment. A video on how to install such an environment can be watched on this video.
Unit tests were prepared with googletest. The description of how it runs is in the video.
Formatting is done using clang-format. The description of the tool configuration is in the video.
The code contains a comment prepared for doxygen, their use is described in the video.
