Many thanks this is very usefull component.
Great work :-)
Can you please tell me how should make the WaveDAC8?
I know the circuit diagram of WaveDAC8 but i can not find the "NO CONNECT" and i also can not make the symbol of it.
So kindly help me with that.
Did you look at the AppNote? You need to import the component into your project, then you can add it to the schematic.
Yes i have seen there but it is not there.
What is not there - the AppNote or the component? For the former - I just tested that its there. If its the latter - did you follow the steps from the AppNote to import it?
How is possible to get the component? Isn't possible to add it to the library? (I'm using PSoC Creator 2.2)
@fransisco: same question to you: did you read the AppNote? On the page there is the download with the component, and a detailed explanation of how to include it in Creatopr and your project.
Hi there, I came across this component and was trying it out.
I simply created a project that generates a sine wave of 1 Hz [....as simple as that].
But when I checked the output on a CRO, the result wasn't as expexcted.
I was getting a sine wave But not a proper one...........The upper half of the wave was fine but the amplitude of the lower half was reduced.
What could be the reason for this?

Can you post a picture of output waveform ?
Is scope DC coupled on vertical amplifier ? Keep in mind
the wavform output has both an AC and DC component, the
DC being its offset, the AC being its peak to peak value. Note
if you are AC coupled many scopes cannot handle 1 Hz as its
intrinsic vertical frequency response.
The problem is solved now...... The error was that I was checking the output on PORT1 of PSoC3 which is a digital port set at 3.3volts....thats why the sine wave amplitude of 4 volt was clipped to 3.3 volts....and so the distorted wave..... Another reason why it should be clearly mentioned that even if a pin is configured as analog in the schematic, it will give a voltage corresponding to digital bank if we give it to a digital port.[as discussed in another forum post.]
