New and low cost product solution for LED matrix display

This paper describes a hardware and software design to display a dynamic message (alphanumeric characters as bitmap images) in LED matrix, from conception, design, dimensioning to realization, with the possibility of having Fixed or scrolling text, Adjustable brightness, Adjustable speed of scrolling and Supports all languages and symbols. The innovation is present in the message to be displayed, ie, from a monochrome bitmap image and by using a program that converts the image into a byte array, we can display any message on the matrix, and the variation of the brightness is done by software (program) by acting on the cycle of a LED's extinction and illumination, in order to optimize the processing time, to have an adjustable adaptation of the display to ambient light, all in a low cost product.
