Name of Product: MB90092 development board Fujitsu video characters OSD
Model of Product: mb90092-demo
MB90092 development board Fujitsu video character development board, is a superposition of fujisu based on the superposition MB90092 company video chip superimposed development board, video through this demo plate can make you a better understanding of the various functions and 90092 rapid application to your needs. Buy the board, Fujitsu will provide the schematic diagram of the board, the source code and a very practical production procedure of fonts.
MB90092 Fujitsu production is the character, in domestic has stack chips of customers, but due to the relatively strong function of chips, more complex, relevant technical data and less, that most users in the use of domestic encountered many problems affecting the user development cycle. This MB90092 developed produce professional DEMO Fujitsu. Through this demo plate can make you a better understanding of the various functions and 90092 rapid application to your needs. Buy the board, Fujitsu will provide the schematic diagram of the board, the source code and a very practical production procedure of fonts.
The most commonly used by the function of composite VIDEO signal (Vin), S - VIDEO input and output, the VIDEO image overlay in black and white color chart, main functions are as follows:
1, the synchronous: in color images on the superposition black-and-white digital image, Chinese, English and Chinese characters, animation, contains the border, background, dimension,
2, synchronization, synchronous background color: under the color, size, color, size change font color, graphics changes;
3, each with Chinese characters showed that,
4 and support NTSC and PAL two kinds of colour (should); crystal,
5 and there are various operating keyboard.
1, MB90092 OSD produce professional demo development board piece
2, 7.5 V dc power supply
3 video signal line
4 data CD a source program and provide C51 principle chart, PCB production data, fonts.
Main USES keyboard, such as internal and external synchronous choice, pushing buttons, various [MODE] the function of presentation. While test plate obligate part in the user interface, user can be carried out on the board.
MB90092 video superposition development board
[function and steps]
To connect power and TV after bat, you can see the effect.
Except for a video signal input interface television, other what all don't need, can see the video demo superposition.
1, to demonstrate good video signal connection board input and output video input signal can connect line of VCD/DVD video camera etc, and the output signal may receive television
2, 6 - power requirements at red lights 9V dc power supply should be lighted page 2 3 pages
In this system, synchronization demo state press MODE key can switch function display screen, basically have the following functions under the synchronization
A set of color, background
B, font size and color
C, pictures and color display/ICONS
D, realizing the function of clock/counter
E, realizing the function of animation
4, press the button to enter EXT synchronous demo status attention to connect the good video input signal and check NTSC/PAL pattern choice (MB90092 crystals for 17.734 MHz as PAL) press MODE key can switch function in color image demo pictures on the superposition black-and-white digital English characters images animation and so on
5, press RESET button can make the system RESET.
The photo with red objects, PCB board of different batches may be different colors, is the latest version, does not affect the function.
Please note: the use of composite video mode superposition color words, when not only superposition grey-black-and-white, if want to outer mode superposition color words, please use RGB model (not lead the development board.
