Hi,
I am trying to use the DSS to perform a mirror without a rotation. I am using the settings defined in Table 15-51. Register Settings for DMA Rotation With Mirroring of the TRM. I am getting the mirror image displayed but with noisy distortions. The same mirror with a 180 deg rotation generates the proper image. The image is a YUV 800x600. Is Table 15-51 and the following correct?
• ba = start address of image buffer in memory
• iw = image width in pixels per row - 1 (for YUV: pixels per row divided by 2) = (800/2) -1 = 399
• ih = image height - 1 (number of rows) = 600 - 1 = 599
• ps = pixel size in bytes (RGB: 2 bytes per pixel, YUV: 4 bytes per pixel) = 4
Thanks,
Paul
