Q:Where is the difference between a LED dot matrix screen and an ordinary LED display?

The universal use of the LED dot matrix screen acts as an information screen for displaying text and simple pictures. If the landlord is fully funded, I would recommend that the landlord consider the LED display. After all, it's more reliable.

Q:I bought a 16X64 LED lattice screen to learn microcontroller, now encountered a problem is how to realize the LED lattice left scrolling LED dot matrix is Chinese characters, I used 8 74HC595 as the column driver, a 74HC154 line scan, the heroes who have no reference to the younger program reference, is used the compilation of the

If there is a program that displays a "static" screen, you can write a program called "left" scrolling.

Q:How to use C language to achieve LED dot matrix display character movement

Do you want 16*16 dot matrix? This C language can be written to move characters to the left

Q:I have a smile LED dot matrix screen, is the reality of man kind, composed of small pieces of a total of 32 fast to form a dot matrix LED screen is welded on the circuit board, the circuit board at both ends of each of a 16 pin interface is the LED lattice screen should buy what kind of driver to control it? Thank you

Are you the only one?. The 32 dot matrix is a unit board.Depends on how much you 74HC595 chip unit board, 16 monochrome, can do text screen for onbon t-card on the line, to 50 yuan. Software works well.

Q:Can a LED8*8 dot matrix display Chinese characters?

Chinese character test, minimum dot matrix 12*12, 8*8, simple stroke, less can also

Q:Two 74HC595 cascade dot matrix 16*16LED driver should not put two pieces of the shift clock pulse together, then the latch output control pulse together, then the serial data output of the first stage is connected to the serial data input to the next level is 9 from 14 is not? If the use of 74HC595 as 16*16 lattice column driver, that should not be displaced 16 times and then output? Can...

If 74HC595 is used as the column driver for the 16*16 dot matrix, should it be shifted 16 times and then output? But I have a little bit of it. There are only accumulators in the microcontroller that can perform shift operations, but it has only 8 bits. How can that be achieved by 16 bit movement?2, 595, 16.

Q:But instead of 16*96, it doesn't flash! The crystal oscillator is 11.0592M. By line scanning ~ please expert advice ~!

May be related to the program delay, 16*128 display takes up a long time, dot matrix screen scanning shows that after the next time between the long time, there will be flashing phenomenon.

Q:What do you mean by row drive in LED dot matrix display?

In fact, there is no such a point, there is only one way to drive, not scanning is staticJust the individual IC control, 4953 control line, 595 control column

Q:Speed is 1, the speed is faster, but the display is normal, there will be no ghosting phenomenon, when speed is 2, 3 and 4, the speed is slow, but there will be ghosting phenomenon, what is the reason ah? Solving? The following is a scan display module program #include<STC12C5A32S2.h> #include _nop_ ("intrins.h"); / / call delay function with #include i...

First, send data to the 595 mile, but not latch (do not give the SRCLK pulse), this time the normal display of the original dataNext, the 138EN is set low to turn off the display595 latch (giving the SRCLK pulse) output138ABC update display position, EN set high, open displaySo there will be no ghosting. If so, it shows that the device is slow, and proper early warning is displayed

Q:LED dot matrix display screen LED

LED has been widely valued and developed rapidly. It is inseparable from its advantages. These advantages are: high brightness, low working voltage, low power consumption, miniaturization, long life, shock resistance and stable performance. LED has a bright future, and is developing towards higher brightness, higher weather resistance, higher luminous density, higher luminous uniformity, reliability and panchromatic.
