STEVAL-LLL015V1

The STEVAL-LLL015V1 is a board with 96 individually driven LEDs controlled by eight LED1202 LED drivers. The drivers are connected to the same I2C bus and share a master clock for common sequence timing. Each LED can be programmed to perform an individual 8-step pattern sequence (single shot or repeated). The panel is configured using the STSW-LED1202GUI, and the user can program several light effects using a basic language interpreted by the firmware. The scripts are written in a dedicated area of the GUI and can be debugged before downloading them onto the board. Once downloaded, the board can execute the scripts without requiring the use of PC software.

The LED1202 is a 12-channel low quiescent current LED driver; it guarantees 5 V output driving capability and each channel is able to provide up to 20 mA with a headroom voltage of 350 mV (typ.) only. The output current can be adjusted separately for each channel by 8-bit analog and 12-bit digital dimming control.
