Understand the progress of hardware development masters! The younger brother has a question to consu

In fact, you should make it clear what the development is about. What is the big difference between the development of a complete set of refrigerator controllers and the development of an LCD module?

If it is an LCD module, first of all, you must understand the driving method of the LCD screen in your hand (you can consult the manufacturer or dealer). Choose the right CPU. Establish the peripheral circuit between the CPU and the LCD screen according to the driver requirements. Then program the CPU and you're good to go.

In terms of program processing, it is first necessary to communicate with the main controller of the refrigerator, because the display is displayed according to the requirements of the main controller. There are many communication methods, such as I2C, UART, etc., depending on the specific requirements. Then the signal of the main controller is processed, and the LCD screen is driven to display the corresponding content according to the requirements.

In the case of air conditioning controller development, it is even more complicated. It involves compressor drive, temperature control, safety protection and so on. Generally speaking, it is necessary to first select the CPU that can meet the requirements, develop the peripheral circuits, and write a program that meets the requirements of the CPU.

To make it clear in all aspects that I can write a master's level graduation **, it is too painful. Hehe.

Finally, in response to your question, I would like to add that different CPUs have their own development environments (compilation environments), and many CPUs support C language development. It must not be difficult for you to learn software.

This should fall within the scope of embedded development. You can see what system is used for the module of the LCD display of the refrigerator, if it is based on J2ME development, you will learn J2ME, if it is Linux embedded development, you will learn Linux embedded development. These are the two that are used the most.

I would like to ask here, I have a software that needs to be modified, can a knowledgeable friend help me? Thank you in advance! There is a reward for re-scoring the problem solved.

Hello:— The first possibility: hardware problems, mainly the data cable, the power cord is not in good contact, please re-plug the wire to ensure that the plug is in good contact.

The second problem: virus infection, typical manifestations are frequent restarts, crashes and other phenomena. It is best to completely disinfect the virus, or you can reinstall the system.

The third problem: software issues. If the newly installed software is incompatible, conflicting, or contains viruses.

The fourth problem: it is not excluded that the power supply is unstable, and the hard disk has bad sectors (logical bad sectors, hardware bad sectors), etc.

Go online to the next hard disk detection software, check the hard disk, and determine whether it is the hard disk.

Reinstall the system first, and if it is not solved, it is a hardware problem.

Reinsert memory, hard disk, etc., without solving the words. Use the substitution method to eliminate the cause of the failure.

For example, if you get a new memory, it's a memory problem.

If you don't have the conditions, please find a professional to fix it.
