what is "native mcu code"

per Google AI ...

"Native MCU code" refers to the code that is directly understood and executed by a microcontroller (MCU) without any intermediate translation or interpretation, essentially the machine code or assembly language specific to that MCU's architecture.

Here's a more detailed explanation:

• Microcontroller (MCU): A small computer on a single chip designed to control specific embedded systems.

• Native Code: Code that is directly executable by the hardware (CPU) without needing a virtual machine or other intermediary.

• Machine Code: The lowest-level programming language, consisting of binary instructions (0s and 1s) that a CPU can directly understand.

• Assembly Language: A low-level programming language that uses mnemonics (short codes) to represent machine instructions, making it more readable than machine code but still very close to the hardware.

• Why it matters: Using native code for MCUs allows for:

  • Direct hardware control: You can directly manipulate the MCU's registers and peripherals, giving you fine-grained control over the device.

  • Optimized performance: Native code can be more efficient and faster than code that is interpreted or compiled on top of a virtual machine.

  • Low-level access: You can work directly with the hardware, which is useful for tasks like embedded systems programming.
