In 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...
READ MOREPart 3 focuses on displaying images on the ILI9341 by transferring pre-formatted pixel data from the STM32 to the display’s GRAM. It explains how image data is structured, converted to the appropriate color format, and efficiently written to the...
READ MOREIn this fifth part of the guide, we connect the web user interface to the STM32 hardware peripherals to enable real interaction with the system. This demonstrates how browser-based controls can monitor and manipulate embedded resources, bridging...
READ MOREPart 2 focuses on initializing the display controller and establishing reliable communication between the STM32F429 and the ILI9341 over SPI. It then introduces the fundamental draw pixel routine, forming the basis for all higher-level graphics...
READ MOREPart 6 focuses on implementing the master-side firmware required to perform write operations to specific registers on the Modbus RTU slave. This section covers constructing valid write request frames, managing data payload formatting, and...
READ MOREPart 1 introduces the STM32F429-Discovery board, covering its onboard resources, including the integrated display, and guides you through setting up the development environment using STM32CubeMX and importing the project into STM32CubeIDE. It...
READ MOREIn this fourth part of the guide, we move beyond simple responses and begin building a basic web user interface that runs directly from the STM32. The web assets will be hosted by the Mongoose HTTP server, demonstrating how embedded devices can...
READ MOREPart 5 focuses on implementing address filtering so that the Modbus RTU slave responds only to requests directed to its assigned slave address. This ensures that in a multi-device RS-485 network, each slave processes and responds only to frames...
