[b][size=4]Question 1: I would like to ask a question about the use of LM3630A. When we use one LM3630A, two LED strings are driven at the same time, and the other string cannot detect a short circuit...
How do mobile phones usually obtain data from the Internet? For example, I see a lot of weather forecast information on mobile navigation maps. Do I need to build a WAP website? Or is there an interfa...
Structure of the Bluetooth protocol stack
The CH583 chip has a built-in Bluetooth Low Energy (BLE) module. Although we have used it once in the previous section, we have not conducted a more in-depth ...

Introduction
Power subsystems are becoming more and more integrated into the overall system. Power systems have moved from being separate "essential dangerous devices" to being monitorable...[Details]
DSP (digital signal processor) is used more and more frequently in today's engineering applications. There are three main reasons for this: first, it has powerful computing power and is capable of ...[Details]
From the PIC16F946 datasheet, we know that there are two ways to write values to the LCD for display:
1. Directly write the value to LCDDATA1~LCDDATA23
2. Use disconnect t...[Details]

1. Disadvantages of choosing too high a voltage level
Choosing too high a voltage level will result in too high an investment and a long payback period. As the voltage level increases, the...[Details]
We know that the inverter consists of two parts: the main circuit and the control circuit. Due to the nonlinearity of the main circuit (switching action), the inverter itself is a source of harmoni...[Details]
In today's body control module (BCM) designs, savvy engineers are moving away from electromechanical relays whenever possible. Their next step is to eliminate fuses. But is eliminating fuses a nece...[Details]
