Description
STEVAL-ILL002V4
demonstration board based on the STP08DP05
Data brief
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).
