1. Synchronous and Asynchronous Transmission 1.1 Concepts and Examples Using everyday examples to illustrate what synchronous and asynchronous mean: Synchronous: A friend calls to say they are coming to my house for dinner, and I wait for them at home. Asynchronous: A friend arrives at my house unexpectedly without prior notice. The difference lies in … Read more
As TI employees, we are often asked if there are any insights or tips we have when designing with RS-485. To this end, we have compiled a series of comprehensive tips that must be remembered when using RS-485. And usage methods…… 1) Use twisted pair cables with Zo = 120Ω or 100Ω 2) Connect bus … Read more
Serial communication is one of the most basic communication methods faced by electronic engineers, and RS-232 is the simplest among them. However, many beginners often cannot clearly understand the relationship and differences between UART and RS-232, RS-422, and RS-485. This article will discuss these concepts to help clarify their relationships. Communication issues, like traffic problems, … Read more

However, many beginners often struggle to understand the relationship and differences between UART, RS-232, RS-422, and RS-485. This article will discuss these concepts to help clarify their relationships. Communication issues, like traffic problems, also have various scenarios … Read more
Follow “Technical Training” focused on automation education for 14 years UART, I2C, RS485… These communication methods are widely used, but their explanations can be ambiguous. Therefore, I feel it is necessary to organize them for clarification and differentiation. The article is a bit long, so I suggest saving it for later reference when needed. UART … Read more
If our board only has 4 interfaces: V3.3, SWDIO, SWDCLK, GND. Then the connection relationship with JTAG is shown in the figure below: Pay attention to the direction of the notch. Then GND can be connected to any pin on the left (except for the bottom pin). The 20-core to 4-core wire should be short; … Read more
Effective postoperative wound management is crucial for preventing potential complications such as surgical site infections (SSI) and wound dehiscence (SWD). Key principles of postoperative wound management include timely wound assessment, appropriate wound cleansing and dressing use, and early recognition and active treatment of wound complications. Appropriate postoperative surgical wound care is vital for preventing potential … Read more
Shear wave elastography (SWE) is a new ultrasound technology developed in recent years, widely used in the diagnosis and differential diagnosis of diseases of the liver, breast, thyroid, prostate, and others[1]. The limitation of SWE lies in the algorithms for assessing tissue elasticity, which neglect the impact of tissue viscosity. Viscosity can also characterize the … Read more
SWD skin grafting has been a traditional treatment method for vitiligo with over 30 years of clinical application! This procedure is recognized by both doctors and patients due to its simple operation, definitive efficacy, and low complication rate! SWD skin grafting has no rejection, a high survival rate of melanocytes, and faster repigmentation. So, can … Read more
Identification of SWD (Surgical Wound Dehiscence) SWD can occur at any time post-surgery, from 1 day to over 20 days after the operation, but generally occurs between the 4th and 14th postoperative days. Possible Signs of SWD SWD can occur without any signs. Incisions at risk of dehiscence may show signs of inflammation that exceed … Read more
