Before we begin: 1. This article will focus on Microchip’s products. I believe Microchip has the most articles on clocks among MCU companies. The terminology used by Microchip may differ from that of other companies, but the usage is the same and does not affect understanding. 2. The term “clock source” is used to distinguish … Read more
Power Supply: If the microcontroller is having issues, first check the power supply. There may be a problem with the power supply. Use a multimeter to check the power supply voltage of the microcontroller; it is best to use an oscilloscope to capture the voltage waveform because the voltage may be unstable (for example, voltage … Read more
In embedded system design, electronic engineers need to focus on multiple core elements to ensure the system’s stability, performance, and reliability. This article will delve into these elements and summarize them, hoping to help our friends. 1. Power Management Power is the cornerstone of embedded systems, and its stability is crucial. Engineers must pay attention … Read more
1. What is a Clock Signal The clock signal (Clock Signal) is the foundation of sequential logic, used to determine when the states in logic units are updated. It is a signal with a fixed period that is independent of operation. The clock signal has a fixed clock frequency, which is the reciprocal of the … Read more

1、Passive Crystals——Passive crystals require an oscillator within the DSP chip, with recommended connection methods provided in the datasheet. Passive crystals do not have voltage issues; the signal level is variable, meaning it is determined by the oscillation circuit. The same crystal can be used for various voltage requirements, making it suitable for DSPs with different … Read more
I previously open-sourced the ESP32C3WROOM board, and today I’m open-sourcing the ESP32C3FH4. You can directly obtain the engineering files at the Lichuang Open Source Square. https://oshwhub.com/zctnb/works Actually, the chips are the same, but the ESP32C3WROOM is a module, while the ESP32C3FH4 is a chip that integrates 4MB of flash. Let me explain for those who … Read more
A microcontroller is the core component of embedded systems. Circuits using microcontrollers are much more complex due to programming, but adding and changing new features is easier with microcontroller circuits. This is why more and more devices, such as electrical appliances, are using microcontrollers. As a project for microcontroller R&D design, its minimum circuit working … Read more
