It also organizes the current application status of domestic MCU chips for reference by practitioners. 1. Introduction to Control Chips Control chips mainly refer … Read more
“ Developers who are new to microcontroller (MCU) development often find themselves confused: should they manipulate registers directly or use library functions? This is akin to choosing between manual and automatic transmission — the former offers precision but is complex, while the latter is simple but lacks a sense of control. This article uses STM32 … Read more
