mini2440 VGA Module xilinx fpga development board

mini2440 + VGA Module xilinx fpga development board


Would be extremely Ling, list of small hills
·China's first launch up to 1024x76 @ 70Hz resolution, low-cost solution for VGA output

·FPGA + SDRAM-based program implemented by the FPGA to control the clock, horizontal and vertical scanning, definitely not flash!

·provide linux, Wince5.0, uCos2, bare metal test source code
Look at the actual shooting of the video effects: mini2440 + VGA running wince in super player, one of the mouse to drag the progress bar when the card will look when it comes to direct play more smoothly.


You need to know:
Currently some 2440 development board provides the VGA 800x600 resolution claimed output expansion modules, most of the DA converter with programmable chip solutions. Please note: programmable means to initialize the main chip set, which can be 2410 or 2440 to achieve its own GPIO can also be achieved by a simple microcontroller.



If you are using 2410/2440 GPIO implementation itself, this part of the code is generally in the Bootloader, it is different from the state of linux systems or WinCE driver source code; present, most manufacturers are the target development board files (. O ) form the initial set up, does not provide the actual source code.



If you are using the MCU, then this is equivalent to a VGA extension of the adapter plate all ready, as the application is concerned, users do not care about its implementation, in fact, most of the liquid crystal display panels have similar VGA , but it is just a "reverse" conversion (AD).



Somewhat similar to our second approach used, except that we do not use ready-made dedicated DA converter chips, but according to the timing needed to VGA display, use the FPGA + SDRAM way to achieve, and this can make full use of 2410 / 2440 itself has a LCD Controller, enabling higher output resolution.



Because of VGA extension in fact, itself borrowed from the 2440 LCD controller functions to achieve, so it's driver is how to set these registers, which an ordinary TFT LCD drivers are similar.




VGA driver source code location in the system:
linux kernel: kernel-2.6.13/arch/arm/mach-s3c2410/mach-qq2440.c the keyword "VGA1024768" part of the set, which in the past and QQ2440 kernel kernel already exists.
Wince5 of the BSP: smdk2440/inc/s2440.h the keyword "LCD_TYPE_VGA1024x768" part of the set.
uCos2 in: uCos2 S3C2440 source lcd.c the keyword "LCD_TYPE_VGA1024x768" part of the set.
Bare metal test code: 2440test src LCD_VGA_1024x768.c

The following pictures are real shot, were running linux + qtopia, WinCE5.0, uCos2 boot, 2440test boot image
