Break away from continuous polling loops by utilizing the STM32F4’s External Interrupt/Event Controller (EXTI) to capture asynchronous hardware events instantly. This guide demonstrates how to map a physical pin to an interrupt line using Low...
READ MOREBy offloading time management to the SysTick timer interrupt, you can replace blocking delays with a non-blocking, interrupt-driven time base that keeps your CPU free for other tasks. This guide demonstrates how to configure the 24-bit...
READ MOREIn this sixth part of the guide, we configure the STM32 system to synchronize its internal time with an NTP server over the network. This demonstrates how Mongoose can be used to obtain accurate real-world time for applications such as logging...
READ MOREMastering the BMP180 begins with establishing a robust communication bridge between the STM32 and your development environment. By prioritizing the configuration of UART and enabling floating-point formatting, you create a foundation for precise...
READ MORETransition from driving outputs to interpreting the physical world by configuring the STM32F4’s GPIO pins as digital inputs using Low Layer (LL) drivers. This guide covers how to read external signals with minimal latency, ensuring your firmware...
READ MOREIn Part 6, we elevate our project by integrating the Light and Versatile Graphics Library (LVGL), transforming raw hardware drivers into a professional-grade graphical user interface. You will learn how to bridge your touch and display drivers...
READ MOREMaster the balance between hardware control and code efficiency by leveraging the STM32F4’s Low Layer (LL) drivers for direct register access. This introductory guide walks you through a lean project setup and GPIO configuration to execute a...
READ MOREIn Part 2, we shall develop the core firmware and driver logic required to translate time data into the TM1637’s custom serial protocol. This section focuses on implementing the precise bit-banging timing and segment mapping necessary to display...
READ MOREIn Part 5, we transition from hardware configuration to data acquisition by implementing the logic required to extract precise X and Y coordinates from the STMPE811. We will explore how to poll the internal FIFO buffer and convert raw analog...
READ MOREThis guide demonstrates how to interface an STM32 microcontroller with the TM1637 display module to create a real-time digital clock, focusing on implementing the custom two-wire serial protocol and effective time formatting. In Part 1, we shall...
READ MOREPart 4 focuses on initializing the touch controller and establishing communication between the STM32 and the touch interface hardware. It also demonstrates how to read the controller’s device ID to verify correct configuration and ensure the...
READ MOREPart 7 focuses on the slave firmware responsible for receiving and processing Modbus write requests. In this section, the slave parses the incoming frame and stores the transmitted register values into the internal register map so that they can...
