In this STM32 Nucleo tutorial, we will learn to use ADC and read analog input voltage using STM32CubeIDE and HAL libraries. We will discuss three methods to read ADC including polling, interrupt, and DMA method. This will be demonstrated with the help of an LED dimmer example where we will connect the potentiometer as an … Read more
In this STM32 Nucleo user guide, we will discuss how to configure timer module in input capture mode to measure the frequency of an input signal. We will program our STM32 Nucleo in STM32 Cube IDE and build a frequency counter whereby one input capture channel will be enabled to capture an external signal on … Read more
In this STM32 Nucleo tutorial, we will learn how to configure and handle timer interrupts using HAL Library in STM32Cube IDE. We will demonstrate this through an example by toggling an LED after a set number of time. Timer interrupts in STM32 pause the sequential execution of a program loop() function for a predefined number … Read more
In this tutorial, we will show you how to use STM32 Nucleo UART with DMA to transmit and receive data through direct memory access without requiring to involve CPU. In DMA mode, data can be transferred from UART RX data register to user memory without any CPU processing time. By using DMA with UART, we … Read more
In this tutorial, we will learn to use GPIO pins of STM32 Nucleo and we will demonstrate it with an LED blinking example using STM32CubeIDE and HAL libraries. We will see how to configure the GPIO pins of STM32 Nucleo as digital output pins. If you’re a beginner in STM32 Microcontrollers, this article will be … Read more
In this tutorial, we will learn to interface STM32 Blue Pill with 4-digit 7 segment display and program it in STM32CubeIDE. Firstly, we will introduce you to the 4-digit 7 segment display, its connection with the STM32 Blue Pill and then move forward to create and build a counter display in Cube IDE. The counter … Read more
