16f628a

Hi Guyes´!

Sorry it´me again :(

But a question. I was starting a project with a Pic16f628a, and want to use an analog input, but when I try to add analog inputI get the message:

"not possible to use this component, the microprossesor need at least one analog input".

When I look at the chip, I see AN0, AN1, AN2, AN3 Am I misunderstanding something. If anybody would try it´s easy, start a new project, select Pic16f628 and try to add an ACD from the inputlist.
Maybe it doesn´t support analog input.

Best regard

Jorgen

Hi Jorgen,

I'm afraid that the 16F628A has only 2 analogue comparators, no A/D converters.

The 16F88 is pin compatible and does have A/D.

Best Regards

Brian
