The Universal Asynchronous Receive and Transmit (UART) interface is found on a variety of peripheral devices. Consider, for instance, a microcontrollerbased system with four such ...

Edge-triggered interrupts are useful in microcontroller (MCU) applications for processing asynchronous events like switch closures, level transitions, and pulses. However, low ...

[Tiziano Bacocco] decided to use UART signals as a type of PWM to create audio. That’s right, he’s plugging the serial TX line straight into a speaker.
