Can arm7 drive a 7 inch display?

7 inches should be divided into digital screen or analog screen. For digital screens, you can use LPC2478 (with TFT-LCD driver port).

The display effect has nothing to do with your single-chip microcomputer, but only the quality of the screen, the color of the glass, and the brightness of the glass.

Remind you that the STM32F1 series of single-chip microcomputers cannot directly drive the 7-inch screen, and can only drive the cavity crack module type.

You can search for Ruixian Technology, they have this, and there is a routine with STM32, you can light it up when you get it.

Yes, if the display resolution requirements of the computer are not very high, it is completely possible, and the 7-inch LCD resolution on the market can generally reach *600, which is basically satisfactory for general applications. Of course, the 7-inch LCD generally does not have a special interface connected to the computer, which needs to be customized. You can also design and make it yourself, which is difficult to implement.

Not necessarily, it depends on what your LCD screen was used for before, and some are used as ** displays, such as electronic photo albums.

It doesn't seem to work, I haven't used it like this, so let's see if its current and voltage are consistent with the relevant parameters of computer monitors.

OK. For details, please consult Garni Hawk, focusing on automotive LCD displays. 7 inch computer monitor, see picture below:

Yes, but you need to buy a driver board.

First of all, you must understand the interface type of the TFT screen you have at hand, if it is a TTL signal, you can use S3C2440 to drive it directly;

If it is LVDS, there must be LVDS to TTL chip conversion.

Secondly, you have to know whether the gamma circuit of your TFT screen and the backlight driver circuit are available, and if you don't have one, you have to make up for it, otherwise, you will never be able to drive it.

Finally, it's the turn of timing, of course, it's the TTL signal, which is very simple, as long as the following parameters are configured.

#define lcd_width 800

#define lcd_height 480

#define lcd_pixclock 1

#define lcd_right_margin 15 //horizontal back porch=86，#define lcd_left_margin 100 //horizontal front porch=1，#define lcd_hsync_len 10 //hsync valid width=128

#define lcd_upper_margin 5 //vertical vack proch=31，#define lcd_lower_margin 21 //vertical front porch=1，#define lcd_vsync_len 1 //vsync valid width=2，

First, the logic is the same, if the connection is the same, the amount of change will be very small.

Second, if there is no GUI, then you need to carry out the lowest operation of the LCD screen, such as initialization, drawing points, drawing lines, these most basic tasks need to be completed by yourself, it is best to use a GUI to reduce these troubles, otherwise your waste of energy is not a little bit or two.

Hello :— The load on the nucleus of the driving plate has increased. If the quality of the 7-inch LCD driver board is not too hard, it will increase the heat. Although it is possible to finish the work normally for a short time, it will be problematic if it runs for a long time.

Upstairs is dumbfounded, what flowers and snowflakes should be imaginary, RA8875 and SSD1963, there is no such problem.

In addition to the above two, there are also several controllers such as S1D13517 and Epson.

It depends on what applications are mainly done, what functions are required, and what level of your MCU is selected.

If you use ARM9 or higher, you don't need these controllers.

CPLD+RAM is also a way, but SRAM's high-density high-speed RAM such as 1M*16 is very good.

Of course, use RA8875, the function and reliability are incomparable, the 1963 anti-interference is too weak, it is okay to light up the display and play, just make the product! In the past two years, RAIO has also released new products such as RA8876 73 71, which can be used with different resolutions, and the function is better than that of 8875.

This is more annoying,Because I don't know the distribution of those feet,Generally, LCD is driven by a block single-chip microcomputer,To write drivers,Are you doing product development or do you want to find a ready-made port,You can try the manufacturer of that screen。

am489234gtmc?Is this a screen type? It's not made by a big manufacturer.

If you want to configure the driver board, you need to know how many volts the power supply of the screen is, and what interface the screen is... And so on and so forth.

Besides, the 7-inch ,,, what are you going to use it for, 7 inches...

For industrial use, Weilun is OK, there are 7 inches, and the power supply of 220 rpm 24V is OK.
