NXP has launched the MCX A34 mixed-signal Arm Cortex-M33 industrial MCU, an upgrade of the MCX A14x and MCX A15x MCUs, which were introduced in 2024.

As a method of dimming support for visible light communications using a massive LED array, we consider a hybrid pulse width modulation/digitally controlled pulse amplitude modulation (PWM/DPAM) system ...

当 PWM 参数稍小时，亮度有些不足，这可以适当减小一些 限流电阻 的阻值进行弥补。 用来显示 PWM 的 LED，其中的电流是间断的，所以，它的限流电阻可以比平常时小一些，100欧左右，是经验数据。 制作实物电路的时候，大电容就不需要了，不用花钱去买了，呵呵 ...

控制 LED 亮度是电子和 嵌入式系统 中的一个基本概念，在可调光照明，显示背光，甚至电机速度控制中起着关键作用。我们使用脉宽调制 (PWM)来实现平滑和精确的亮度调节，而不仅仅是开关LED。 PWM的工作原理是快速切换LED在ON和OFF状态之间的高频。亮度是通过改变占空比来控制的，占空比代表了 ...

Among all the Arduino boards, the Uno is most folks' go-to choice, and for good reason. It's the perfect platform to get started with Arduino, it's capable enough to handle a wide range of tasks, and ...

This paper presents the analysis of brightness fluctuation for camera images under the PWM dimming LED Illumination environment and countermeasures against it. The exposure dose of a camera, which ...

The Julia programming language is a horrible fit for a no-frills microcontroller like the ATMega328p that lies within the classic Arduino, but that didn’t stop [Sukera] from trying, and ...

A CPU-efficient AVR Arduino software PWM library for resolutions of 8 to 16 bits on an arbitrary number of digital output pins - leomeyer/MultiPWM ...
