LED Control Library

Library to handle the X-NUCLEO-LED61A1 LED Control Expansion Board based on the LED6001 component.

Platform compatibility

  • NUCLEO boards have been tested with the default configuration provided by the HelloWorld_LED61A1 example.
  • NUCLEO-F070RB, NUCLEO-F072RB, NUCLEO-F091RC boards have been tested with the following patch:
    • to connect with a wire the NUCLEO’s D9 pin to the LED61A1’s D6 pin;
    • to initialize the pwm PinName variable with D9 rather than D6.
  • NUCLEO-F302R8 board has been tested with the following patch:
    • to connect with a wire the NUCLEO’s D7 pin to the LED61A1’s D6 pin;
    • to initialize the pwm PinName variable with D7 rather than D6.
  • LPCXpresso11U68 board has been tested with the limitation of using only the PWM Dimming, as it provides only one PWM channel, thus allowing just one between the PWM or Analog Dimming functionalities. It has been tested with the following patch:
    • to connect with a wire the LPCX’s D3 pin to the LED61A1’s D4 pin;
    • to connect with a wire the LPCX’s D4 pin to the LED61A1’s D6 pin;
    • to initialize the xfault_irq PinName variable with D3 rather than D4;
    • to initialize the pwm PinName variable with D4 rather than D6;
    • to initialize the analog PinName variable with NC rather than D5;
    • to disable the use of the user button in any application example as it is not available.
  • FRDM-K64F board has been tested with the following patch:
    • to disable the use of the user button in any application example as it is not available.
