Is anybody has the example problem for AD/DA converter controled by PIC16F84?

[pub_longb]

In my circuit( Multisim 9), I use PIC16F84 as the MCU to control the DAC and ADC. I want to ask if anyone has the example problem for the controlling?
Further more, the I/O port of PIC16F84 seems can not be connected with the digital output of DAC, so I asked myself, is it right that for PIC16F84, the I/O port can only connected with the serial port of DAC and ADC? Or it needs a converter to adapt to the  input  port of DAC?

Looking for any help! Thanks!

Please describe the problem with more details or in germany if you comes frome here.

Can you attach your example to this forum question ?

What do you want exactly do with the PIC ?

You can test the new Design Circuit Suite (includes Multisim10 with MCU10 and Ultiboard 10 with Ultiroute10). When you open Samples you find the folder MCU with PIC folder. In these you can find some examples to PIC16F84. With that as pattern you should solve the problem.

I attached you here the MCU examples in the *.zip

Thanks for your reply, Johann,

I want to use PIC16F84 to control the calibration of DA/AD Converter, in another word, I would like to control the value of the feedback variable resistor to change the amplify times via this MCU, and by this way, I can check the output of DAC is exactly equal with the input of ADC.But the problem is, that I can not communicate the output of DAC with the input of ADC through the I/O port of PIC16F84.

If you are familar with this kind  of MCU device, hope you can help me to check the circuit which I attached. Thanks.
