ADC conversion not working in SimulIde 1.0.0

Hello,

While working on a project, we have noticed a bug regarding the ADC functionality in SimulIde 1.0.0 with use of an atmega328. The problem which seems to be specific to SimulIde 1.0.0, is that the converted digital value is always 0 for any input voltage.

To illustrate the issue, we have created a minimal working example which is functioning properly in SimulIde 0.4.15 but doesn’t in SimulIde 1.0.0. It consists of a voltage divider and the MCU transmitting the converted value.

We attached the example to this post.

Could you help us with this issue? Thank you a lot and thank you for your great work!

Hi.
I think this bug is already solved.

Thanks for reporting anyway.

Ok we have not been on the most recent version, however on revision 891 it doesn’t work for us also.
What is new in revision 891 is that when we load in the circuit there is a couple errors that have not been there before:

ERROR: Register not found: ""
ERROR: Register not found: "EIND"
ERROR: Register not found: "RAMPZ"

891 is not a good revision to build.

What would be a good version to build? Sorry we are not the most experienced with Launchpad.

I did some test and ADC is working for me.

The problem in your circuit is that Aref Pin is not connected.
In 1.0.0 you need to connect it.

Maybe 872 is more stable.

Anyway these errors are not new, just that before they were not reported:

ERROR: Register not found: ""
ERROR: Register not found: "EIND"
ERROR: Register not found: "RAMPZ"

And sorry for the short replies.. I'm in the middle of several things right now.

BTW... Thanks for testing and reportig.

Thank you very much for your super fast help it works now.

Have a very fine day.

Built in 1.10

The ADC's I have used in the real world normally stay at the full voltage reading once the reference voltage exceeded.

In the image, the ADC shows full reading on 3.3V but acts like a "modulo" function once the voltage goes higher than the reference.

ADC text is inverted when pin number grows. (Restarting doesn't fix it).

Hi marroja, thanks for reporting.

Solved at Rev 1934.

Good catch, this one affects all Logic Components.
Solved at Rev 1935.
