| PIC24H question |

I am making one sound related project ( written in past topics ).
Basicly: microphone -- PIC24H -- speaker
What pin should I use for input signal and what pin should I use for output signal ( D/A ) ?
Thank you for your time ! |

I don't have experience with the 24H series, but I can tell that this is a very vague question. | Quote: | | What pin should I use for input signal and what pin should I use for output signal ( D/A ). |
I would suggest you have a look at the datasheet of the particular microcontroller you wish to use.
The microphone (if it is a simple condenser or electret type) will most likely require some sort of preprocessing and amplification before it can be fed to the controller's analog input pin.
Be more specific with your question. Whenever possible, try to include a brief description of what you are trying to attempt, the controller you are using, associated circuitry, compiler version, and maybe code.

Although somewhat vague, the question's intention is basically understandable.
- D/A hardware is only available with some dsPIC33F parts, I think. You should mainly search among these.
- The dsPIC and PIC24 family is said to be usable for DSP applications. This doesn't imply, that any DSP application, e. g. complex digital audio actually achieves sufficient performance with these parts. They are still restricted to sequential code execution. You should do a rough estimation of required numeric operations to determine the basic feasibility. |

Do you have some other solution regarding audio processing.?
Maybe some other chip, maybe some end solution ? |
