This 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...

Part 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...

In 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...

Part 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...

In 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...

One Pulse Mode (OPM) in STM32 timers allows the generation of a single, precisely timed pulse in response to a trigger event, after which the timer automatically stops. This feature is ideal for applications requiring accurate one-shot signal...
