The word "communication module" is often mentioned in the concept of the Internet of Things. Whether in industry news, in-depth articles or industry reports, this term is often seen, such as DDA commu...
1. Introduction
In the previous article, we introduced how to simulate the timing logic of WS2812B through GPIO pins to realize the control and display of colored light strips; however, the method imp...
Our business direction is renewable energy, security , IoT . In addition to knowledge and experience , the ideal hardware engineer is more importantly passionate and capable of learning and adapting q...
Piezoresistive strain gauges are one of the most common types of pressure sensors. They use the change in the resistance of a material when stretched to measure pressure. These sensors are suitable fo...
Analog variable frequency filters require the use of variable passive components. The greater the filter slope, the more variable passive components are required. These components are often potentiom...[Details]
The eye diagram is due to the afterglow effect of the oscilloscope, which overlaps the waveforms of each scanned symbol to form an eye diagram. This article will lead you to understand what the eye d...[Details]

1. First of all, I would like to explain that the STM32 chip I used this time is STM32F103RB, and the resource used is USART1 on the chip. 2. Below is my circuit connection diagram: Note: The circu...[Details]
In the industrial field, small and medium-sized three-phase asynchronous motors are currently the most widely used motor products. Different motors have different application scenarios. With the co...[Details]
1 Introduction With the continuous improvement of the scientific level of sports training, the necessity of human body special strength training has been increasingly valued. Through the overall anal...[Details]
Bluetooth-enabled sensors are used in large-scale logistics operations to track trucks and planes carrying COVID-19 vaccines. In the United States, FedEx and UPS are taking the lead in delivering v...[Details]
1 Introduction
A voltage source, or ideal voltage source, is a model abstracted from a real
power source
. It can always maintain a certain voltage at both ends regardless of t...[Details]
The PD4 pin of stm8s003 is quite special and has three main functions. The following is an explanation of the settings for different functions. Function 1, ordinary IO port: I won't go into ...[Details]
Modern power supplies use switching technology to obtain the required output voltage from the main power supply. However, switching power supplies are usually noisy and cannot be used for sensitive...[Details]
Because MOSFETs are unipolar devices, parasitic capacitance is the only limiting factor for switching transients. The charge balance principle reduces the on-resistance per specific area, and the chi...[Details]
When setting the pin output, I wanted to set it to open-drain output and then output high and low. However, I found that it could not output high (initialized to open-drain low level), and it was alw...[Details]
