STEVAL-ILL059V1

STEVAL-ILL059V1 High brightness LED array driver with diagnostics for automotive applications based on the STAP16DPS05 and STM8A Data brief Description The STEVAL-ILL059V1 evaluation board is a high brightness LED array driver application with diagnostics based on the automotive grade, low voltage, 16-bit constant current LED sink driver STAP16DPS05 from STMicroelectronics. The LED driver is configured and controlled through an 8-bit automotive grade STM8A microcontroller via SPI interface. An automotive grade A5974D DC-DC converter provides the voltages and power for the overall functioning of the board. Features  Stand-alone mode: – Demonstrates pre-configured patterns (with adjustable brightness/speed) such as rolling text, wave effect, dot sequence, etc. – On-board buttons to switch between the demos – Potentiometer as a slider to control speed or brightness of the pattern – Open circuit, short circuit using opencircuit/short-circuit jumpers This board can be used to demonstrate the LED driver features or used to aid in application development. Software applications can be written, downloaded and debugged using the on-board SWIM connector.  GUI mode: – All the features present in stand-alone mode can be controlled using the GUI – Global brightness control to change the brightness of all channels – Frame programming mode and 4 predefined presets with variable transition time between frames – Open/short error detection and representation on the GUI – Error detection in “no loop” and in loop of 0.5 s and 1 s  RoHS compliant August 2014 DocID025915 Rev 1 For further information contact your local STMicroelectronics sales office. 1/6 www.st.com Schematic diagrams 1 STEVAL-ILL059V1 Schematic diagrams Figure 1.
