S3C2440驱动AT070TN83的图像颜色失真
近来做了块底板，用QQ2440驱动群创的AT070TN83屏，现在问题是显示条纹还凑合，一到显示图像不仅方向不对而且还失真很厉害，附件是我写的代码，各位xdjm帮忙看看哈，谢谢。驱动代码ourdev_671623RNBTKQ.rar(文件大小:3K) (原文件名:AT070TN83.rar) 回复【楼主位】freud

另外还有两块底板，需要的人可以送哈。 LZ 垂直与水平信号配置不对~~~
试试这个
#define HFPD_800x480 (40) //水平同步信号的前肩
#define HSPW_800x480 (48) //水平同步信号的脉宽
#define HBPD_800x480 (88) //水平同步信号的后肩
#define VFPD_800x480 (13) //垂直同步信号的前肩
#define VSPW_800x480 (3) //垂直同步信号的脉宽
#define VBPD_800x480 (32) //垂直同步信号的后肩 LZ能送我一块不呢？？ 能送我一块吗， 回复【3楼】milestone2010

我试试看啊。可以送一片给你啦，邮费到付，+我Q告我地址呗。Q：一八0221⑤四 回复【2楼】milestone2010

呃，好像偏的更厉害了。。郁闷 各位大侠帮忙啊 你用的是565模式驱动的吧，换成888的方式试试，我用的AT91SAM9261驱动的颜色还行，下面是配置：
/// Display width in pixels.
#define BOARD_LCD_WIDTH 800
/// Display height in pixels.
#define BOARD_LCD_HEIGHT 480
/// Display resolution in bits per pixel (bpp).
#define BOARD_LCD_BPP AT91C_LCDC_PIXELSIZE_TWENTYFOURBITSPERPIXEL
/// Display interface width in bits.
#define BOARD_LCD_IFWIDTH 24
/// Frame size in pixels (height * width * bpp).
#define BOARD_LCD_FRAMESIZE_PIXELS(BOARD_LCD_WIDTH * BOARD_LCD_HEIGHT * 24)
/// Frame size in words (height * width * bpp / 32)
#define BOARD_LCD_FRAMESIZE (BOARD_LCD_FRAMESIZE_PIXELS / 32)
/// Frame rate in Hz.
#define BOARD_LCD_FRAMERATE 60
/// Pixel clock rate in Hz (frameSize * frameRate / interfaceWidth).
#define BOARD_LCD_PIXELCLOCK (BOARD_LCD_FRAMESIZE_PIXELS * BOARD_LCD_FRAMERATE / BOARD_LCD_IFWIDTH)
/// LCD display type.
#define BOARD_LCD_DISPLAYTYPE AT91C_LCDC_DISTYPE_TFT
/// LCDC polarity.
#define BOARD_LCD_POLARITY_INVVD AT91C_LCDC_INVVD_NORMALPOL
/// LCDVSYNC polarity.
#define BOARD_LCD_POLARITY_INVFRAME AT91C_LCDC_INVFRAME_NORMALPOL
/// LCDHSYNC polarity.
#define BOARD_LCD_POLARITY_INVLINEAT91C_LCDC_INVLINE_NORMALPOL
/// LCDDOTCLK polarity.
#define BOARD_LCD_POLARITY_INVCLK AT91C_LCDC_INVCLK_NORMALPOL
/// LCDDEN polarity.
#define BOARD_LCD_POLARITY_INVDVALAT91C_LCDC_INVDVAL_NORMALPOL
/// Pixel clock mode.
#define BOARD_LCD_CLOCKMODE AT91C_LCDC_CLKMOD_ALWAYSACTIVE
/// Vertical front porch in number of lines.
#define BOARD_LCD_TIMING_VFP 22//132
/// Vertical back porch in number of lines.
#define BOARD_LCD_TIMING_VBP 22///22
/// Vertical pulse width in LCDDOTCLK cycles.
#define BOARD_LCD_TIMING_VPW 1// 1
/// Number of cycles between VSYNC edge and HSYNC rising edge.
#define BOARD_LCD_TIMING_VHDLY 1///??????
/// Horizontal front porch in LCDDOTCLK cycles.
#define BOARD_LCD_TIMING_HFP 210///210
/// Horizontal back porch in LCDDOTCLK cycles.
#define BOARD_LCD_TIMING_HBP 45///45
/// Horizontal pulse width in LCDDOTCLK cycles.
#define BOARD_LCD_TIMING_HPW 1// 1 可现在就接成了5:6:5的方式啊，物理连线已经固定了。 终于解决，但群创的屏的可视范围咋这么小啊，换个角度颜色就偏绿。大家有遇到这种情况吗？ 偏绿的话，你可以看下，我怀疑你的接线不正确，565的话，R0,B0要接地 嗯，我用FPGA驱动好像就没这个问题了。 回复【12楼】freud

你好，请问连接底板还有没
可否留个联系方式
我的QQ 113071811 上面的帖有联系方式呀 哈哈 找到了
