1 Overview of Electric Vehicle Controllers The two-wheeled vehicle controller, simply put, controls the motor, which mainly consists of two parts: Hardware Core: AD sampling, CPU computation, PWM drive Software Core: Motor control algorithms, such as square wave control and FOC control (dual-resistor FOC/single-resistor FOC) 2 MCU Rollout Method Used in Controllers The first phase … Read more
Dear friends, hello everyone! Today, the topic we are going to learn about is the serial communication protocol of microcontrollers (MCUs). This content is quite important and relatively professional, but I will try to explain it in a simple and understandable way. First, let’s see why we need serial communication? Communication is the Basis of … Read more
Embedded system development can be divided into Bare Metal and RTOS (Real-Time Operating System). Bare metal development means no RTOS, with programs running directly on the MCU, where all task scheduling is completely managed by the developer. Bare metal development is suitable for simple tasks, low-power systems, and small embedded devices, but when tasks become … Read more

The first step in implementing embedded software is to enable specific peripherals, features, and subsystems. Some MCU vendors, such as STM32, Microchip, and TI, provide tools within their integrated development environments that allow developers to enable peripherals in their projects and add subsystems to the codebase. However, these tools are tightly coupled with the MCUs … Read more
