This is the second post of my Cortex-M7 without hardware series. In the first part I nailed down the linker script and memory map. Now it is time to take a look at the other half of “boot”: the vector table and the Reset_Handler. ...
This is the first post in my Cortex-M7 without hardware series, which aims to build an Executable and Linkable Format executable (ELF) and run it without hardware (using emulated / simulated STM32F746 microcontroller unit. 1). ...
When working with embedded systems, naming might seem like a small detail, however it is not. Good naming conventions make code readable, maintainable, and portable. Poor naming, like Uart1 or Uart2, ties logic to hardware details, making future changes painful. Semantic names such as UartDebug or UartModem tell you what the peripheral in question does, not where it sits on the MCU. I’ll explore why semantic naming matters, provide a naming table for all layers, one of which I will be using in upcoming examples when writing more about embedded C++, and present sample scenarios that clarify the benefits. These recommendations are based on my experience and general best practices in embedded C++ development. ...
