hey. so the c51 got no dma access. understand. where is the emulator libary? project must do dma access.
"so the c51 got no dma access"
What "C51"?
Keil C51 is just a software development toolset; "DMA" is a feature of a chip - not the tools.
Some 8051-based chips do have DMA; full details will be available from the Manufacturer - this has nothing to do with Keil.
"where is the emulator libary?"
What emulator library?
"project must do dma"
Then you will need hardware that supports it!
Some 8051-based chips do have DMA do not recall seeing one such

OK, not recently - but the Triscend did it!
I guess other 8051-cores in an "SoC" context might also...?
