I want to store WAV music files in ROM. I use s3c44b0+ucos operating system. Now I want to implement a file system to manage it. I have read the uc/fs user manual and fumbled for a long time but still...
rts2800 .lib: C/C++ runtime support library; rts2800 _ml.lib C/C++ large memory mode runtime support library. rts2800 _ml.lib has a lot of floating point operation processing functions, while rts2800 ...
I'm looking for a few big guys to work together on an industrial control system development project. We want to make a modular, CAN-communication distributed pump truck control system, which mainly in...

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...
Do you often have to add brake fluid to your car's brakes? The fact that you need to pump out the brake fluid to make sure there is no gas in the brake fluid line may not be done by the car owner h...[Details]
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]
For a long time, due to the limitation of hardware conditions, the display devices of traditional small handheld devices such as PDA are usually monochrome LCD, and the user interface is very simpl...[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]

1. Tips for charging UPS for the first time
After purchasing a new UPS, plug the UPS into the 220V mains power grid and charge it for at least 12 hours to ensure that the battery is fully char...[Details]
In some motion control systems with simple control or low cost requirements, stepper motors are often used as actuators. The biggest advantage of stepper motors in such applications is that they ca...[Details]
Current sensing in automotive applications includes controlling the current through solenoids and injectors. For example, during diesel injection, we rapidly increase the current to the induction i...[Details]
This paper first proposed an elevator controller algorithm based on a finite state machine, and then designed a three-story elevator controller based on the algorithm. The correctness of the elevat...[Details]
3. Driving circuit design
The power driver uses a field effect tube, which is a field-controlled device with a capacitance effect between the gate and source, so it has high requirements for t...[Details]
Multimedia applications such as mobile TV, mobile gaming, and audio playback present a huge challenge to power management design in mobile phones. Mobile phone designers need to keep the phone smal...[Details]
Conventional crystalline silicon solar cells are made on high-quality silicon wafers with a thickness of 350-450μm, which are sawn from pulled or cast silicon ingots. Therefore, more silicon materi...[Details]
