Using an external voltage reference can significantly improve the accuracy and stability of ADC measurements on the STM32F4. By providing a precise and low-noise reference voltage, the ADC can achieve more consistent conversion results...
READ MOREIn this guide series, we’ll explore how to build interactive graphical interfaces using Riverdi displays, starting with a simple yet powerful example. In this first part, you’ll learn how to create a basic UI that links a slider to a gauge...
READ MORETimer synchronization for three-phase PWM generation allows multiple timers to operate with precise phase shifts, typically 120° apart, to produce accurately timed PWM outputs. This phase-shifted synchronization is crucial in applications...
READ MOREDisplaying a full-screen color image on an E-Ink display demonstrates the device’s ability to render rich visuals using its reflective, low-power technology. In this guide, we will cover how to send and refresh full-frame image data to achieve a...
READ MOREIn this part of the guide, we will bring together all the concepts learned so far to measure temperature from the DS18B20sensor using the 1-Wire protocol. You will see how the STM32 communicates with the sensor, initiates a temperature...
READ MOREIn this part of the guide, the focus is on how the emulated sensor uses interrupts to inform the master about new data availability or status changes. This mechanism mimics real-world sensors that signal the master through dedicated interrupt...
READ MORETimer synchronization on STM32 allows multiple timers to operate in a coordinated manner using trigger modes, enabling one timer to act as a master and others as slaves. This mechanism supports precise phase alignment, cascaded triggering, and...
READ MOREIn this guide, we will demonstrate how to render images on the SSD1331 OLED display by sending bitmap data directly from a C array.Using this function, we can efficiently transfer preprocessed RGB565 image data to the display, enabling full-color...
READ MOREIn this two-part guide, we explore how to interface the DS18B20 temperature sensor with an STM32 microcontrollerusing the 1-Wire communication protocol. The first part introduces the fundamentals of the 1-Wire protocol, explains how the DS18B20...
READ MOREIn this part, we dive into how the STM32 receives data from a 1-Wire sensor, interpreting the precise timing signals that represent logical bits. Understanding the reception phase is crucial, as it ensures accurate communication and reliable data...
READ MOREIn this guide, we demonstrate how to emulate an SPI-based sensor using two STM32 Nucleo-64 boards—one configured as the SPI master and the other as an emulated SPI sensor. In Part 1, we will discuss the importance of this setup and explain how to...
READ MOREThe 1-Wire protocol is a simple, low-speed communication standard developed by Dallas Semiconductor (Maxim) that uses just a single data line and ground for both power and data exchange. It enables multiple devices, such as sensors and memory...
