High-brightness LED driver (40 LEDs) demonstration board with diagnostics based on STP08DP05

STEVAL-ILL002V4

Overview

This demonstration board provides a complete solution for driving 40 high-brightness green LEDs manufactured by Toshiba.

The high-brightness LEDs are arranged on the board in a 5x8 matrix.
The matrix is driven by five 8-channel STP08DP05 drivers which are controlled by the ST7FLITE3x 8-bit microcontroller.
The innovative feature of STP08DP05 is the full output error detection function, which checks the status of the outputs without invasive tests (via software).

Main features

DC-DC converter
Brightness regulation
Animated text
Blinking speed regulation
Graphic user interface (GUI)
Error detection on output
