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
1. Management of SWD SWD can present as superficial to deep wounds, with exposure of internal organs or implants. The goal of managing SWD is wound healing. Management should be tailored to the specific needs of the patient and requires the involvement and collaboration of the patient, family, nursing staff, and a broader multidisciplinary team. … Read more
1. Introduction In the development of STM32 microcontrollers, using SWD for program downloading only requires two pins. So, when do we need to use the microcontroller’s RST port? This involves the pin configuration of the microcontroller. In the CubeMX software configuration, there are five options regarding system debugging settings. If you choose SWD debugging, you … Read more
Click the blue text above to follow for continuous updates!!! Introduction Today, we will also not involve the Zigbee protocol, focusing solely on serial operations in the CC2530 microcontroller. This article uses Serial Port 0 for data transmission. The main function is to send serial data from a PC’s serial debugging tool to the microcontroller, … Read more
Have you heard of the LIN bus? It is often seen in automotive bus design. You might ask, “Isn’t there already a CAN bus? Where does the LIN bus come from?” The reason is simple: the CAN bus is too expensive. If an entire vehicle were to use the CAN bus, the costs would be … Read more

First, buy a Bluetooth module and download a Bluetooth serial debugging assistant on your phone, which is equivalent to the UART serial communication of the microcontroller. Use BUFF to obtain the received data. Here, we only need to focus on one issue, which is testing the encoding. If the APP sends 0xFF, (the APP Bluetooth … Read more
The printf function is indispensable during microcontroller debugging, allowing developers to intuitively and conveniently obtain the current running status of the program. However, in chips like STM32, to achieve printf functionality, UART must be utilized. Is there a way to implement printing functionality solely with JLink? The answer is yes. ARM has adopted a new … Read more
With the development of technology, RS232 serial communication is still widely used in industry. However, in commercial applications, the USB to UART technology has gradually replaced RS232 serial ports. Most laptops no longer have serial ports. So, how can we achieve communication between a microcontroller and a computer? We only need to add a USB … Read more
