STEVAL-ILL002V4

STEVAL-ILL002V4 High-brightness LED driver with diagnostics (40 LEDs) demonstration board based on the STP08DP05 Data brief Features ■ Brightness regulation ■ Blinking speed regulation ■ Animated text ■ Error detection on output ■ Graphic user interface (GUI) ■ DC-DC converter Description This demonstration board provides a complete solution for driving 40 high-brightness green LEDs manufactured by Toshiba. STEVAL-ILL002V4 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).
