STEVAL-ILL090V1

The STEVAL-ILL090V1 evaluation board is based on the ALED8102SXTTR LED driver, which is directly controlled by an STM8 MCU.

It can be supplied via a USB mini connector or through J2 connected to a 12 V power supply.

The board implements two automotive scenarios that you can select via the SW2 switch.

The first one is an ambient light scenario based on three RGB LEDs with configurable brightness and color. You can change color and intensity via the SEL switch and the SW1 rotary switch, respectively. A short flashing signals the right RGB channel selection. If all the RGB channels are flashing, it means that the global brightness has been selected. If no user interaction is detected within about 30 seconds, the RGB LEDs automatically sweep through various color shades. The FADE switch performs a global fade in/fade out action.

The second scenario simulates a motorcycle rear light: two orange LED strips, representing the arrow lights, are placed side by side, separated by a red LED circle, whose function is to simulate the position/stop lights. By slightly rotating the SW1 switch counterclockwise, the left arrow light flashes, whereas a small clockwise rotation makes the right arrow flash memory. The red LED circle brightens up with a medium intensity until the STOP switch is pressed: in this case, the brightness significantly increases, signaling a BRAKE condition. If no user action is performed for a while, the rear tail LED enters the demo mode.
