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...
READ MOREPart 4 focuses on implementing the slave-side response to a Modbus RTU read request issued by the master. In this section, the STM32-based slave processes the received frame, validates the CRC and addressing, and returns a properly formatted...
READ MOREIn this third part of the guide, we implement a minimal HTTP server using Mongoose on STM32 to validate end-to-end web functionality. The server will respond with the system uptime, confirming that the TCP/IP stack, Ethernet interface, and HTTP...
READ MOREIn this third part of the guide, we will build upon the pixel and windowing functions to implement a draw-bitmap routine capable of rendering full images on the GC9A01 display. This will allow us to efficiently transfer and display pre-formatted...
READ MOREIn this second part of the guide, we move from configuration to implementation by developing the GC9A01 driver header and source files for STM32. We will initialize the LCD controller and implement a basic draw-pixel function, using it to render...
READ MOREIn this third part, we explain how to enable and disable individual cores on the STM32H747 and control their startup behavior. The section also covers how one core can release or start the other during runtime, enabling coordinated dual-core...
READ MOREIn this second part of the guide, we integrate the Mongoose source and header files into the STM32 project and walk through the required configuration steps for a successful build. We then bring up the Ethernet interface and verify basic network...
READ MOREPart 3 of the guide moves beyond basic link verification and introduces practical Modbus RTU transactions in which the master issues read requests to the STM32-based slave. This section focuses on implementing and validating standard read...
READ MOREThis guide introduces the 1.28″ Round LCD Display Module featuring the embedded GC9A01 driver and SPI interface, highlighting its key features, electrical and mechanical specifications, and overall capabilities. Part 1 focuses on...
READ MOREIn this second part, the guide focuses on debugging firmware on the dual-core STM32H747 with particular emphasis on observing variables during runtime. It explains how to attach the debugger to each core, inspect memory and registers, and track...
READ MOREIn this first part of the Mongoose guide for STM32, we focus on the foundational steps required to get the platform up and running, starting with the hardware setup and basic system initialization. We also cover UART configuration to enable...
READ MOREPart 2 of this guide focuses on establishing and validating the communication link between a Modbus RTU master and the STM32-based slave using a simple echo mechanism. The master sends a complete Modbus RTU frame and the slave returns the same...
