Read Array from Application Log

[hgb1992]

Hello!

I want to use some DP2xx Display for application logging. But I need the logged data in application too.
I have to write the value into the app log and in the next program loop I use this data for calculation the new value for the app log (like a RAM).

Can I use the function "Read Arry from Application Log" with any DP2xx? Because in every .hwd I tried, the function was disabled.

Will this use generate some problems with the storage or anything like that?

Thanking you in anticipation!

Kind regards,
Benedikt

Hi hgb1992

The "Read Array from Application Log" is for the moment only available for DP6xxLX display hardwares.
Have you considered using the NV-memory?

Hello Daniel,

thanks for your answer.

I didn't think on NV memory, because it has a limited opportunity for overwriting. Do you know the detailed quality of possible overwrites?

I will write on the memory several times per second, therefore I think the NV will have a defect after short time.

Do you have a good suggestion for a cheap solution without a DP600LX, because the user only needs a very easy display and a "save" value also after supply disconnections. So I have to save as much.

Thanking you in anticipation.

Kind regards, Benedikt

Hi

When it comes to displays, the NV memory can be used without limit since they are using FRAM as a memory instead of EEPROM (that is otherwise commonly used among controllers).

So the NV memory should be possible for you to use in this case.
