Serial communication with UART or USART is common way to transfer message between MCU and PC or other devices. The UART of the Nucleo-64 board can be configured to either use interrupt or not. If UART is configured with interrupt then the data trans…
The STM32F401RE Nucleo-64’s UART offers three methods—polling, interrupts, and DMA—to handle serial communication, each with trade-offs. The previous stm32 programming tutorial used LED control via a MAX232 and DB9 port from a PC. In brief, polling …
In the last UART controlled LED STM32 programming tutorial a led connected to STM32 Nucleo-64 board was controlled with message received from PC through the UART. In that tutorial HAL uart function HAL_UART_Transmit() and HAL_UART_Receive() were use…
Learn how to implement UART-based LED control on the STM32F401RE Nucleo-64 board. This comprehensive guide covers serial communication basics, GPIO configuration, and practical implementation using STM32CubeIDE. Introduction Serial communication is …
The STM32F401RE Nucleo-64 is a versatile development board from STMicroelectronics, powered by the STM32F401RE microcontroller (MCU). This ARM Cortex-M4-based MCU, running at up to 84 MHz, offers multiple clock sources that make it suitable for a wi…
Looking to control an LED using your Arduino and a serial connection? In this tutorial, we’ll show you how to use Tera Term(a popular terminal emulator) installed on a PC to send commands through a DB9 connector and MAX232 chip to turn an LED on and…
Crystal oscillators are essential for generating stable frequency signals in applications like RF circuits and microcontroller clocking. This guide shows you how to build a simple Pierce crystal oscillator for reliable frequency output. Why Use a…
