Anonymous users2024-02-0651 single-chip microcomputer is relatively simple, you can weld a minimum subsystem on the empty board, and then add a running lamp module, these lines are relatively simple, you can do it yourself. If you say that you want to draw a PCB board and then open the board, it is more expensive, not enough per square meter according to one square meter, about three or four hundred yuan per square meter, but if you want to mass produce, you can open the board. In addition, the smallest subsystem and the flow lamp module are welded on two small boards, and then connected by wires to achieve functional modularization.

Anonymous users2024-02-05You don't need the whole development board, the development board has more functions, and it is for you to develop. The running water lights on the billboard are just very simple, so just install a minimal system and connect the drive.

Anonymous users2024-02-04You can make a PCB board for the smallest system of a microcontroller, and then lead to control the level of the lamp! If your street light is powered by high voltage, you can choose to control a switch to control the current conduction.

Anonymous users2024-02-03Just weld the microcontroller and the running lamp separately, and then write it into the microcontroller in the way you want it to be bright.

Anonymous users2024-01-31I don't understand what it means, what is a real flowing water lamp, not controlled by a single-chip microcomputer?

Anonymous users2024-01-30Replace the peripheral circuit of the development board with the peripheral circuit that supports the real lamp and remove other unnecessary peripheral circuits, and then draw the PCB board according to the schematic diagram and then send it to the PCB factory for proofing, some PCB factories can directly give them the schematic diagram and let them draw the PCB board.
The current and voltage supported by the lighting of the development board are very small. If you have knowledge of circuits, you can design them yourself, or ask someone else to design them.

Anonymous users2024-01-28Crystal oscillators, reset switches, resistors, microcontrollers, capacitors! However, I haven't used the AT89S52, so you'll have to calculate the exact parameters yourself! If you use another microcontroller, you may be able to assemble it based on its data!

This can be done with the 3-terminal chips of the 78xx series. The peripheral circuit is very simple, and there is no need to use a single-chip microcomputer. If you make a constant current source with adjustable current, you can consider single-chip microcomputer +78xx (such as ).
It's really not good, but you really have to rely on yourself to learn single-chip microcomputers at work, and the function of the training institution tells you how to **. I've been graduating for 6 years, and I really miss school life, my suggestion is to learn a few things that need software for work, and learning ARM microcontroller does not conflict, the first important thing is to draw PCB boards, what version of software can be, such as AD6, etc., hehe I still use 99SE, a bit embarrassing. If you don't know how to draw the circuit diagram of the PCB you design, you often can't make the physical diagram so that the work is limited, you must cooperate with others to work, at one point if you do some of your own experimental boards, if you want to turn the idea into reality and have to ask someone to do something, the second point of light will be single-chip microcomputer will not design the circuit is very unpopular, and the circuit that will not draw the PCB design often adds a lot of difficulty to the person who draws the PCB board (the drawing will not be assigned to the single-chip microcomputer or arm pin position, so that many lines are super long, and even winding a lot of wires, It's easy for others to change your drawings). >>>More
For how to learn single-chip microcomputer, I think it is still necessary to master its hardware, storage structure, assembly must be proficient, because the introduction of assembly is very helpful and understand the hardware, if you learn single-chip microcomputer, and then learn other, such as arm, at this time you can only be familiar with the assembly, but the first time to learn single-chip microcomputer, assembly, must be proficient, I mean at first do not use c to write programs, write with sinks, write can 10 20 assemblers, your assembly will go to the next level, In the future, you'll be using C for development, and you'll see how comfortable it is to optimize C with a solid foundation for assembly. Regarding the study of microcontrollers, I think it is necessary to have: >>>More
