PWM stands for Pulse-Width Modulation. Once the switching frequency (fsw) has been chosen, the ratio between the switch-on time (TON) and the switch-off time (TOFF) is varied. This is commonly called duty-cycle (D). The duty cycle can be between 0 and 1 and is generally expressed as a percentage (% ...
A Digital to Analog Converter(DAC) performs the task of converting digital words of n bits into voltages whose amplitude will be proportional to the value of the code expressed by the words themselves. Since the input binary words represent a succession of finite codes, the voltage coming out of a ...
An Analog to Digital Converter (ADC) converts a continuous signal (usually a voltage) into a series of discrete values ??(sequences of bits). The main features are:
Resolution (in analog terms): It is the minimum variation of the analog input voltage that can determine the variation of the LSB, ...
The SPI (Serial Peripheral Interface) protocol, or rather the SPI interface, was originally devised by Motorola (now Freescale) to support their microprocessors and microcontrollers. Unlike the I2C standard designed by Philips, the SPI interface has never been standardized; nevertheless, it has bec ...
EEPROMs (Electrically Erasable Programmable Read-Only Memories) allow the non-volatile storage of application data or the storage of small amounts of data in the event of a power failure. Using external memories that allow you to add storage capacity for all those applications that require data rec ...
Hello friends, I hope you all are doing great. In today's lecture, we will have a look at the I2C Communication with STM32 Microcontroller board. I am going to use the Nucleo board for today's lecture. In the previous lecture, we have discussed STM32 Serial communication both in Interrupt Mode and p ...
USART is the acronym for Universal Synchronous-Asynchronous Receiver-Transmitter, and is the advancement of the old UART that was unable to handle synchronous communications; in computers, it deals with the management of communication via the RS-232 interface.
Generally, in the communication between ...
We will use for our examples STM32CubeIDE released by ST and completely free. STM32CubeIDE is a development tool and supports multi operative system (SO), which is part of the STM32Cube software ecosystem. STM32CubeIDE allows using a single platform to configure peripherals, to generate/compile/deb ...
To become familiar with the world of microcontrollers it is necessary to have a development board (also known as a kit), which generally allows you to start working on it easily. Fortunately, the ST provides a wide portfolio of development boards. In this guide, we will describe and use the Nucleo ...
In this guide, we will explain step by step to start programming on the STMicroelectronics (STM) platform, especially the STM32 family.
The term, "STM32" refers to a family of 32-bit microcontroller integrated circuits based on the ARM® Cortex®M processor. The architecture of these CPUs (Central Pro ...
