1. Introduction to UART Universal Asynchronous Receiver/Transmister (UART) is the asynchronous communication standard for microcontrollers and other peripherals. UART is a point-to-point communication standard, that is, in a network, only one device plays the role of Transmister and one device plays the role … Continued
1. Introduction to PWM Pulse Width Modulation (PWM) is a method of pulse width modulation or adjustment of the output voltage intensity value. PWM is commonly used in motor control. Some of the concepts of PWM include: Duty cycle : high … Continued
1. About Timer Timer is an integrated peripheral in most microcontrollers, providing users with many useful applications such as accurately determining a time interval, measuring – counting input pulses, controlling output waveforms , PWM pulse hashing, etc. STM32f103C8 has all … Continued
1. System ticks and applications System tick is a 24-bit timer located in the ARM Cortex M core. This is a down counter, the task of the system timer is to count from the reload value loaded in the SysTick … Continued
1. What is an interrupt? Interrupts are simply understood as random events that interrupt the course of an ongoing event. To make it easier to understand this new concept, let’s give an example in practice as follows: For example: During working … Continued
1. Theory of GPIO GPIO (General Purpose Input/Output) is a shared output or input pin. Why shared? Because each GPIO pin in addition to Input / Output functions, they also have other functions corresponding to other peripherals. For example: I2C, SPI, UART, ADC… … Continued
