Description
The STEVAL-ILL073V1 is a high brightness,
RGB LED array driver system evaluation board
with local dimming and diagnostics based on the
ALED1642GW independent PWM LED driver
controlled through an STM8A microcontroller SPI
interface.
A 16 RGB LED matrix is driven by three
ALED1642GW LED drivers, one for each
channel; i.e., Red, Green and Blue.
The on-board A7986A DC-DC converter,
accepting standard adapter input voltages,
provides the voltages and power for the overall
operation of the board. The STEVAL-ILL073V1
includes a USB-UART daughterboard bridge for
communication with a PC.
The evaluation board is also equipped with
jumpers to simulate LED open circuit and LED
short circuit faults, and a 4-pin SWIM connector
to debug and to develop the STM8
microcontroller firmware.
The STEVAL-ILL073V1 has two modes of
operation: in standalone mode, the evaluation
board is controlled via on-board buttons and a
potentiometer; in GUI mode, a Graphical User
Interface is provided to represent the drivers.
When connected to PC, the evaluation board
enters GUI mode and the GUI has control of the
board.
