What is Bare Metal Programming?
Bare metal programming is the practice of programming a computer or microcontroller without using an operating system or any other software layer between the hardware and the code. It involves writing code that directly interacts with the hardware, using low-level programming languages such as Assembly or C. This allows for greater control over the hardware, as you have direct access to the processor, memory, and other resources.
In the case of Raspberry Pi, bare metal programming involves writing code directly to the hardware, using low-level programming languages such as Assembly or C.
| Advantages | Disadvantages |
|---|---|
| Provides direct access to the hardware, enabling greater control over system resources | Requires advanced knowledge of low-level programming languages such as Assembly or C |
| Avoids the overhead and complexity of operating systems and middleware | Requires more effort and time to develop and maintain code compared to high-level programming languages or using an operating system |
| Enables faster and more efficient code execution | Lack of abstraction and protection from hardware errors can lead to more complex and error-prone code |
| Ideal for applications with strict timing requirements or low-latency communication with hardware peripherals | Difficult to integrate with higher-level software stacks or libraries |
To get started with bare metal programming on Raspberry Pi 3B+, you’ll need the following tools:
- Raspberry Pi 3B+: This is the main hardware component you’ll need to get started with bare metal programming on Raspberry Pi.
- MicroSD card: You’ll need a MicroSD card to store the operating system and your code. A capacity of 8GB or higher is recommended.
- Cross-compiler: This is a toolchain that allows you to compile your code on a different platform (such as a PC) and generate code that can run on the ARM-based Raspberry Pi. You can use the GNU ARM Embedded Toolchain or other cross-compilers.
- Text editor: You’ll need a text editor to write and edit your code. Some popular free options include Notepad++, Nano, and Visual Studio Code.
