Description

Formatting system and addressable lighting device

The present invention relates to a format setting system and an addressable light-emitting device that utilizes the format adjustment of the direct memory access area to match various format drivers.

When controlling the addressable light-emitting diode, the microcontroller transmits the corresponding color data frame to the driver on the addressable light-emitting diode through the peripheral interface according to the color data frame of the addressable light-emitting diode.
