X-NUCLEO-LED61A1

The X-NUCLEO-LED61A1 is an expansion board based on LED6001. The expansion board is equipped with a single-channel, constant-current LED driver for boost or SEPIC topologies. The X-NUCLEO interfaces with the STM32 microcontroller. It is compatible with the Arduino™ UNO R3 connector. The brightness of the LED string connected to its output can be controlled through a PWM signal (0 % - 100 % dimming) or a control voltage (analog dimming). Open/Short LED fault, feedback disconnection, LED overcurrent and output-to-ground short-circuit (SEPIC only) faults are detected and managed through the LED driver. The expansion board is designed to provide examples for applications involving several LEDs arranged is a single string (e.g., indoor and architectural LED lighting, off-grid street lighting, emergency LED lighting, white goods, gaming, etc.).

Examples

There is 1 example with the X-NUCLEO-LED61A1 library.

X_NUCLEO_LED61A1_HelloWorld: This application provides a simple example of usage of the X-NUCLEO-LED61A1 LED Control Expansion Board. It shows how to control a LED stripe load connected to the board by means of a sinusoidal wave form injected into the PWM dimming control pin.
