PIC External USB Interface Chip (PIC to PC) or External DAC

[miggarcbs]

Hello every one...

I'm developing a project where I need a PIC with not only a 10 bit ADC and a 10 bit DAC, but also USB communication with my PC.

The problem is there is no Microchip PIC with USB, 10bit ADC and 10 bit DAC simultaneously.

The only PICs with USB, 10 bit ADC and also DAC, have 5 bit DACs (at least with DIP package), which is a very low DAC resolution for my application.

Here I have two options:

1-
To opt for a PIC with internal USB, internal 10 bit ADC, and add an external 10 bit DAC.

2-
To opt for a PIC with internal 10 bit ADC, internal 10 bit DAC, and add an external USB interface chip.


The question is:

With Flowcode 6 professional (PIC pack), is it easier* to control an external USB interface chip (between PIC and PC)
or an external DAC ?

* Obviously it depends on Flowcode user experience.
I'm a Flowcode (near) beginner (although I have a good background in PICs internal architecture and have some PIC Assembler knowledge).
Here, for easier, I mean which solution is more "straight ahead" in terms of Flowcode "out of the box" components
and definitely which one gives less headaches.

All ideas, suggestions and examples are absolutely welcome.


Also, if you have ever used Flowcode with external DAC (10 bit or higher) or external USB chip interfaced to a PIC,
please refer its part number.
