ST / Mbed 2 deprecated LedDimming_LED61A1

Test application for the STMicroelectronics X-NUCLEO-LED61A1 LED Control Expansion Board showing several LED control modes.

Dependencies:   X_NUCLEO_LED61A1 mbed

Fork of LedDimming_LED61A1 by ST Expansion SW Team

LED Control with the X-NUCLEO-LED61A1 Expansion Board

This application provides an 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 through the following control modes:

  1. Manual PWM Dimming;
  2. Manual Analog Dimming;
  3. Sinusoidal PWM Dimming;
  4. Sinusoidal Analog Dimming;
  5. Photo-based Analog Dimming.

The button of the MCU board, when available, can be used in the following ways:

  • Short Button Press [<0.5s] for Manual Dimming;
  • Medium Button Press to Switch Demo;
  • Long Button Press [>2s] to Switch Power ON/OFF.

The program starts in mode 1.
