You said " from 1 volt range to 2 volt range " but
Is it typo of 4.08 volt range huh?
As you know, cydwr file / System TAB / Operating Conditions will address VDDA value
But I'm not sure how it to work in actually.
Still, I'm not sure what is your problem clearly.
Yes, I made a mistake, sorry. I did in fact mean I was changing from 1 volt to the 4 volt range. The problem is I get notes that I interpret as warnings when i do a clean and build. Being mainly a programmer, it is my nature to address all warnings and notes. They're given for a reason.
So, what is a NOTE or Warning?
Please post or attach it.
I was wrong, say again.
What is written in the NOTE and Warning?
I would guess that your Vdda is set to 3.3V. Check the design-wide ressources for that...
I had a issue with Vdda, in cydwr file / System TAB / Operating Condition, Vdda is set up as 5V, but in the Vdda pin in the chip, I see a 3.3 V value, shouldn't it be 5 V also ?
It not shouldn't be 5.0V
PSoC doesn't do voltage boost up as the design-wide notations.
It just only tell to the PSoC, the real voltage of VDDs.
The voltage applied actually takes priority.
Thanks PSoC73, but it isn't totally clear to me really. So, the Vdda pin voltage is not under my control ? If changing the Vdda in cydwr file does not actually modifies it in the real pin, what is the role of setting up cydwr ? Is there a way to accomplish 5 V in Vdda pin without external devices used explicity for it ? Feeding Vdda pin with the voltage I want would be a mistake ?
[ Is there a way to accomplish 5 V in Vdda pin without external devices? ]
Yes, You can use a boost converter that accepts an
input voltage supplied by a battery or other source.
That is detailed in TRM, Section 15: Power Supply and Monitoring.
And cydwr setting is Creator Hep / Using Design Entry Tools / System Editor.
I'll take a look in this section, thanks again !
This might help (from TRM) -
The settings in the design wide resources are to inform the hardware compilation / placement process about the conditions set up on the board. This is needed because e.g. the analog voltage influences certain parameters which need to be set for analog components. The same is for the digital voltage, which e.g. influences how USB connection handling works.
So if you need a specific analog and digital voltage, you need to set them up externally (e.g. by the jumpers on the dev kits). Remember that Vdda needs to be the highest voltage in the system...
Hi there...i've had this confusion before as well......suppose the "cydwr" settings and the hardware jumper settings on the kit have different values, which one would take precedence over the other?
The external HW on the board sets power pin voltages. But your settings in
the cydwr window also effect device operation.
PSoC Creator Settings for Device Power
PSoC Creator automatically configures components for
optimal performance for the voltages applied to the power
pins. To do this, PSoC Creator needs to know the value of
these voltages. The System tab in the PSoC Creator
project's design-wide resources (DWR) window is used for
this purpose, as Figure 2 shows.
