In Part 1 of this two-part series, “Creating Uniform LED Luminescence in RGB Displays”, the discussion focused on dot correction. This design technique is used for managing individual pixel brightness ...

The TPS7510x linear low dropout (LDO) matching LED current source is optimized for low power keypad and navigation pad LED backlighting applications. The device provides a constant current to up to ...

High-brightness LEDs (HBLEDs) are making inroads into more traditional lighting applications that include a dc distribution system (for example, 24-V MR-16 track lights). HBLEDs are more efficient, ...

peripherals.brightness (board.BACKLIGHT on the PCA9554 I/O expander) is enabled as an output on startup, and is set originally to True. Setting it to False leaves it as an output. If the A1/PWM jumper ...

While all of my own devices and monitors don't have PWM dimming for their backlighting, there are some monitors at work which do appear to use PWM. Now many of these monitors are years old, and I ...

This project demonstrates the use of ADC and TIM peripherals to control LED brightness level by varying the duty cycle of the generated PWM signal using a potentiometer. UART and I2C are also ...

Most of us are aware that charlieplexing can drive a large number of LEDs from a relatively small number of I/O pins, but [David Johnson-Davies] demonstrates adding another dimension to that method to ...
