【原】LCD参数转换

 cfg |= S3C_VIDTCON0_VBPDE(time->v_bpe - 1);
 cfg |= S3C_VIDTCON0_VBPD(time->v_bp - 1);
 cfg |= S3C_VIDTCON0_VFPD(time->v_fp - 1);
 cfg |= S3C_VIDTCON0_VSPW(time->v_sw - 1);

 cfg |= S3C_VIDTCON1_VFPDE(time->v_fpe - 1);
 cfg |= S3C_VIDTCON1_HBPD(time->h_bp - 1);
 cfg |= S3C_VIDTCON1_HFPD(time->h_fp - 1);
 cfg |= S3C_VIDTCON1_HSPW(time->h_sw - 1);

由此得出

 

v_bpe = VBPDE + 1;
v_bp  = VBPD + 1;
v_fp  = VFPD + 1;
v_sw  = VSPW + 1;
v_fpe = VFPDE + 1;
h_bp  = HBPD + 1;
h_fp  = HFPD + 1;
h_sw  = HSPW + 1;
