Having worked in the embedded industry for seven or eight years, I would like to share some hardware circuit design schemes and insights for those who are new to embedded systems. 1. Key Circuit R1 Pull-up Resistor: It clamps the uncertain signal to a high level through a resistor, maintaining it in a non-triggered state … Read more
With the development of the times, microcontrollers have become one of the essential learning topics for many electronic engineers. However, learning microcontrollers is not easy. If you master the following eight knowledge points or techniques, learning microcontrollers will be much more efficient! 1. Choosing Pull-Up ResistorsIn microcontroller circuits, the choice of pull-up resistors is very … Read more
1. Choosing Pull-Up Resistors for Microcontrollers As can be seen in the reset circuit, when resistor R1=10k, RST is high, but when R1=50, RST is low. Clearly, R1=10k is incorrect, as the microcontroller remains in the reset state and cannot function. This occurs because the RST pin contains a transistor, which allows a small cutoff … Read more
How can one learn microcontrollers effectively? This article shares six key experiences from senior engineer Liu Ping, hoping to resonate with everyone. 1. Correct Understanding of Microcontrollers Understanding microcontroller technology correctly is essential; it’s not unattainable, nor can it be mastered in just ten days. If this technology were so difficult and profound, how could … Read more
1. What is a microcontroller? A microcontroller is a single-chip microcomputer that integrates a microprocessor, memory, and I/O interface circuits on one integrated circuit chip. Intel launched the MCS-51 series microcontrollers, which integrate an 8-bit CPU, 4KB ROM, 128 bytes RAM, 4 8-bit parallel ports, and 1 full-duplex serial port, along with 2 16-bit timer/counters. … Read more
As a part of the Mechatronics College, the upcoming courses will all involve microcontrollers. So, what exactly is a microcontroller? Let’s take a brief look with Mechatronics Guru! Basic Introduction A microcontroller is an integrated circuit chip that uses very large scale integration technology to integrate a central processing unit (CPU) with data processing capabilities, … Read more
There are many sensitive components inside a microcontroller, and these components are very sensitive to external factors. If they are affected by electromagnetic interference, it can easily lead to the system not operating normally and stably. Therefore, electronic engineers must take reasonable measures to enhance the anti-interference performance of sensitive components. So how should this … Read more
Introduction The STM32 series chips are developed based on the Cortex-M3 core. They adopt the industry-leading Cortex-M3 core architecture, utilizing Harvard architecture and the Thumb-2 instruction set. They can achieve 32-bit performance with a 16-bit code density. Additionally, with single-cycle multiplication instructions, hardware division instructions, and a built-in fast interrupt controller, STM32 chips can run … Read more
1. Reset (1) What is Microcontroller Reset The reset of the STM32 microcontroller refers to the process of resetting the microcontroller to its initial startup state. The reset behavior causes all running programs to terminate and restores the microcontroller’s registers and functions to their initial values. The reset process provides a known starting state for … Read more
