I have been studying embedded systems recently. I may not have read the materials in detail. I also combined them with some small programs to study them. I have the following doubts. 1. The semaphore ...
Look, this is at89x51.hThe bit definition in sfr SCON = 0x98; sfr SBUF = 0x99; So the address of the buffer overlaps with the address of SCON.1. How can it be that the address overlaps? Does this regi...
Microchip's PIC18F46J50 is a low-power, high-performance 8-bit USB microcontroller (MCU) using nanoWatt XLP technology. The current in deep sleep mode can be as low as 13nA, the operating voltage i...[Details]
Today, with the increasing integration of functions, mobile phones can also be used as portable media players (PMP), digital cameras, handheld computers (PDAs), and even global positioning systems ...[Details]
introduction
Throughout the history of automotive lighting, power has always played an important role. Initially, cars only needed headlights to see the road in the dark. Later, other light so...[Details]

Two simple circuits are implemented to drive two LEDs from a battery powered microprocessor.
This design is based on a circuit that uses three resistors and a microprocessor I/O pin as an input h...[Details]
Power management solutions for today's portable application processors are becoming increasingly integrated. Total power consumption, standby and sleep current consumption affect battery size, bill...[Details]
5. Identifiers and keywords of C language
A complete PIC microcontroller C language program usually consists of six parts: include files (i.e. header files 1, variable definitions, variable de...[Details]
Microcalorimetry
is used to determine energy relationships. Microcalorimetry techniques are often required when performing calorimetric experiments with small sample sizes or slow heating rat...[Details]
General LED lighting has a current limiting resistor in the driving circuit, and the power consumed by the resistor has nothing to do with the LED light emission. In order to improve efficiency, a...[Details]
I've been studying dot matrix recently. It looks simple, but it takes a while to master it completely! The 8*8 dot matrix hardware circuit I'm making now is like this. The row is driven by 74HC138 + t...[Details]
1 Introduction
There have been many studies on the detection and protection of power grid short circuit and line fault. The short circuit, overload and overvoltage protectors on the market have ...[Details]
The concept of state machine
State machine is an important concept in software programming. More important than this concept is its flexible application. In a clear and efficient program, ther...[Details]
Single-chip microcomputers are widely used because of their small size, powerful functions and low price. This article introduces the method of designing a micro electronic piano using the AT89C51 sin...[Details]
