STEVAL-ILL073V1

STEVAL-ILL073V1 RGB LED driver for automotive lighting based on ALED1642GW and STM8A Data brief 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. Features         High brightness 4 x 4 RGB LED matrix Complete hardware and software package Various preconfigured and programmable patterns Open / short error simulation and real-time detection 6 to 28 V DC polarity-independent power supply GUI for advanced driver configuration USB-UART bridge for PC connection RoHS compliant January 2016 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.
