Bus Buses are everywhere. Signals in this world are the same, but there are thousands of buses, which can be quite confusing. In general, there are three types of buses: internal buses, system buses, and external buses. Internal buses connect various peripheral chips with the processor within a microcomputer; system buses connect plug-in boards with … Read more
In embedded development, interfaces such as UART, I2C, and RS485 are commonly used. Understanding them may be ambiguous, so this article organizes them. The article is lengthy, with an estimated reading time of about 10 minutes. UART (Universal Asynchronous Receiver-Transmitter) The UART port refers to a type of physical interface (hardware). UART is an asynchronous, … Read more

During a business trip to a new energy factory, I was tasked with upgrading the firmware to resolve a bug. The microcontroller needed to have a .hex file reprogrammed, but the product was already sealed, making it impossible to open. Therefore, I had to use the CAN bus to update the firmware via a Bootloader. … Read more
Introduction In circuit design, level matching is a fundamental requirement, yet it is often overlooked, which can lead to device failures and communication anomalies. In this article, we will reveal how to avoid device failures caused by level mismatches and provide practical design advice to ensure your circuit designs are both efficient and stable. Level … Read more
iNature Sonochemotherapy (SCT) triggers an excessive production of reactive oxygen species (ROS) and controlled release of chemotherapeutic drugs through ultrasound, becoming a powerful cancer treatment method. However, achieving spatiotemporal controlled release of chemotherapeutic drugs during ROS generation remains a significant challenge. On December 17, 2024, a collaborative research paper titled“Cascade-Activatable Nanoprodrug System Augments Sonochemotherapy of … Read more
