What i need is to transfer the data in 2D transfer to make the data image overlay on the bugger image.
memcpy_all(Img_Data, 128, 128, 16, 16, Img_Buff+323152, 128, 128, 16, 16);
The function i used is below & the Msize Configured is 16 Bytes
void memcpy_all(int8u * pSource, int16u nSrcXCnt, int16u nSrcYCnt, int16u bySrcXMod,int16u bySrcYMod, int8u * pDestination, int16u nDstXCnt,
int16u nDstYCnt, int16u byDstXMod, int16u byDstYMod)
{
*pREG_DMA21_ADDRSTART = pSource;
*pREG_DMA21_XCNT = nSrcXCnt;
*pREG_DMA21_YCNT = nSrcYCnt;
*pREG_DMA21_XMOD = bySrcXMod;
*pREG_DMA21_YMOD = bySrcYMod;
ssync();
*pREG_DMA21_CFG = ENUM_DMA_CFG_ADDR2D | ENUM_DMA_CFG_STOP | ENUM_DMA_CFG_MSIZE16 | ENUM_DMA_CFG_PSIZE04 | ENUM_DMA_CFG_SYNC | ENUM_DMA_CFG_READ ;
*pREG_DMA22_ADDRSTART = pDestination;
*pREG_DMA22_XCNT = nDstXCnt;
*pREG_DMA22_YCNT = nDstYCnt;
*pREG_DMA22_XMOD = byDstXMod;
*pREG_DMA22_YMOD = byDstYMod;
ssync();
*pREG_DMA22_CFG = ENUM_DMA_CFG_ADDR2D | ENUM_DMA_CFG_STOP | ENUM_DMA_CFG_MSIZE16 | ENUM_DMA_CFG_PSIZE04 | ENUM_DMA_CFG_SYNC | ENUM_DMA_CFG_WRITE;
*pREG_DMA21_CFG |= ENUM_DMA_CFG_EN;
ssync();
*pREG_DMA22_CFG |= ENUM_DMA_CFG_EN;[[e
ssync();
while((*pREG_DMA22_STAT & BITM_DMA_STAT_RUN) >> BITP_DMA_STAT_RUN);
Delay(0xFF);
*pREG_DMA21_CFG &= ~ENUM_DMA_CFG_EN;
ssync();
*pREG_DMA22_CFG &= ~ENUM_DMA_CFG_EN;
ssync();
}Kindly help me to overlay an image data to the Centre of image buffer
Edited the unwanted links in function
