Hello everyone, I am a ruffian balance, is a serious technical ruffian. This series of riffraff to introduce you is the ARM Cortex-M kernel microcontroller related knowledge.

ARM kernel architecture (M series since 2004, so far the Cortex – M family already contains nine architecture (M0 / M0 + / M1 / M3 / M4 / M7 / M23 / M33 M35P, a qualified architecture (M microcontroller developers must have full understanding to the kernel, Read the kernel manual is the main way to understand the kernel, and for Cortex-M software developers can also start from the CMSIS (Cortex-M Software interface standard) to understand the use of the kernel step by step.

This series of articles will cover ARM Cortex-M kernel microcontroller development.
