The C-DM-0002S-SL module is intended for the control of addressable LEDs, which can be used either directly in the form of a classic strip or various assemblies of these LEDs (mechanical arrangement in a matrix, etc.).

In total, one module can control up to 500 LEDs connected in one row. The LED strip can be powered either from an external source or directly from the 5 V output of the module (maximum current 1 A).

Control

The DATA output structure is used to control the individual LEDs.

Tab. 2  List of commands

 

After sending the new data, they are processed by the module and as a confirmation of receipt, the value of the received command is copied to the input zone in the ACK parameter. In order to detect the successful receipt of a recurring order, it is divided into 2 parts:

- bit0-4 command (viz table 2)

- bit5-7 counter, when it is incremented, individual commands can be recognized

 

Selected color (value 0 – 55) based on the palette Fig. 1.

Color map

LED settings in separate colors. The transmission of control data must be divided into "pages" and gradually sent to the module.

 

 

Subdata

 

Animation

Automatic animation generating a transition between 2 colors or a "traveling one". Meaning of parameters:

- period period between individual steps (in 10ms)

- steps number of animation steps

- mode  – 0 color transition, 1 "traveling one" forward, 2 "traveling one" backward

 


 

Reset animation

Resetting the animation. When the index value is 0 - 4, a specific animation is reset, another value resets all active animations.

 

Stop animation

Stop animation. When the index value is 0 - 4, a specific animation is stopped, another value stops all active animations.
