Part 1 introduces RS-485 as a robust, differential serial communication standard widely used in industrial and embedded systems for its noise immunity and long-distance capability.In this part, we focus on STM32 HAL configuration and the...
READ MOREIn this second part of the guide, we move from configuration to implementation by developing the ST7789V2 driver header and source files for STM32. We will initialize the LCD controller and implement a basic draw-pixel function, using it to...
READ MOREThis guide explains how to configure and use TIM1 on STM32F4 to generate precise PWM and complementary PWMN signals with configurable dead-time insertion. It covers the principles of dead-time generation, complementary waveform synchronization...
READ MORETIM1 is an advanced-control timer on STM32 microcontrollers designed for high-performance applications that require precise timing, complementary PWM generation, and robust safety features. This guide explains the key capabilities of TIM1 and...
READ MOREIn this guide, we shall see how to receive data using UART in LIN configuration. In this guide, we shall cover the following: 1. STM32CubeMX Setup: We shall pickup from the previous guide from here. Open LIN_Bus project from STM32CubeMX. Once the...
READ MOREIn this multiple-part guide series on LIN (Local Interconnect Network) bus for STM32F4, I will cover its fundamentals and implementation. In this guide, we shall cover the following: What is LIN Bus: Introduction to LIN Bus: LIN was...
READ MOREDifferential mode in the STM32 ADC allows measurements based on the voltage difference between two input pins rather than a single-ended signal referenced to ground. This approach greatly improves noise immunity, increases measurement accuracy...
READ MORECascading two 16-bit timers on the STM32 allows you to build a fully synchronized 32-bit extended timer, overcoming the counting limitations of a single 16-bit peripheral. By configuring one timer as the master and the other as its...
READ MOREIn this first part, we will introduce the ST7789V2 display controller, its key features, and how it interfaces with STM32 microcontrollers. We will also walk through setting up the STM32 project in CubeMX to prepare the foundation for driving the...
READ MOREUsing Timer1 as the external clock source for Timer2 on the STM32F4 allows Timer2 to advance strictly in response to Timer1’s output events, ensuring perfect hardware-level synchronization. This configuration is crucial in applications that...
READ MOREUsing 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 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...
