In 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...
READ MOREThe 2.15-inch E-Paper display is a low-power, high-contrast screen that mimics the appearance of printed paper, making it ideal for battery-powered and sunlight-readable applications. In this guide, we will explore how to interface it with an...
READ MOREThis guide demonstrates how to interface a Nokia 5110 display based on the PCD8544 controller with an STM32 microcontroller using the U8G2 graphics library. We will cover hardware setup, library integration, and display initialization to build a...
READ MOREIn this guide, we will focus on the firmware side by initializing the SSD1331 controller and preparing it for operation. Once initialized, we’ll implement a simple routine to draw a single pixel on the OLED display as the foundation for more...
READ MOREIn this part of the guide, we will extend the emulated sensor by introducing control over the rate of its internal ADC conversions. By adjusting this rate, the slave STM32 can mimic real-world sensors that allow the master to configure sampling...
READ MOREUsing DMA in normal (non-circular) mode with the IDLE line interrupt turns UART reception into a smart, event-driven system. Instead of blindly filling buffers, the DMA captures bursts of unknown-length data in one shot, and...
READ MOREThis guide demonstrates how to interface a GLCD12864 display based on the ST7920 controller with an STM32 microcontroller using the U8G2 graphics library. We will cover hardware setup, library integration, and display initialization to build a...
READ MOREThis guide walks you through working with the SSD1336 SPI color OLED display using STM32 MCUs. In part one, we’ll cover the SSD1331 controller basics, environment setup, and hardware connections to get started. In this guide, we shall cover the...
READ MOREIn this part of our UART guide series, we will explore how to receive data of unknown length using interrupts triggered on each incoming character.This approach allows the STM32 to handle variable-length messages efficiently, reacting in real...
READ MOREIn this part of the guide, the emulated I²C sensor will act as a data source, sending predefined or dynamically generated values back to the master upon request. This simulates the behavior of real sensors, where the master first selects a...
READ MOREIn this part, we focus on receiving data using both polling and interrupt-driven methods. Polling continuously checks the UART status flags for incoming data, while interrupt mode allows the CPU to handle other tasks and only responds when data...
