#88256 - How to Map DAC ADC into external RAM?
Responding to: ???'s previous message
Thanks for reminding. I have few 8255. But currently not yet start using and the project is due very soon.

I hope you can explain method of using RAM to ADC and DAC.

What you mean is send the result of ADC to RAM then when we want the result, we can display it by retrieving from RAM?

8255 is for I/O port extension.

Because the design have used port 0 and port 2 for addressing, so How I going to use I/O port for DAC and ADC?

Can I connect the DAC and ADC at between 74HC373 and 8052 for data ports? The diagram can refer at link below. That is one of the guidline which is similar to my design.
