i would like to get help to export my data from diffbind into ChIPPeakAnno for annotation

I tried, contrast=1, bNormalized=TRUE,bCalled=FALSE, bCounts=FALSE, bCalledDetail=FALSE,bAll=TRUE,file="test",ext="csv",DataType=DBA_DATA_RANGEDDATA)               

but the output is not recognized by ChIPPeakAnno as an input..

I can't reproduce this.  When I try:

> rep =,contrast=1, bNormalized=TRUE,bCalled=FALSE, bCounts=FALSE, bCalledDetail=FALSE,bAll=TRUE,file="test",ext="csv",DataType=DBA_DATA_RANGEDDATA)

followed by

> library(biomaRt)
> library(ChIPpeakAnno)
> m = useMart('ensembl')
> m = useDataset('hsapiens_gene_ensembl',m)
> a = annotatePeakInBatch(rep,mart=m,featureType = c("TSS") )

I get annotations successfully.   Can you provide more specific information regarding what you tried, and what the error message was, including the output of "sessionInfo()"?
