displaying signed 8 bit integers using a data plug-in

[Stefan2]

Hi there,

I'm currently using DIAdem 10.1 and I'm writing a data plug-in in order to read binary data. What I'm missing is a data type "eI8" to read and display 8 bit signed integers. Obviously, to get the data into a channel, I have to use the data type eByte, but how do I make DIAdem display it as a signed value in the data portal?

Many thanks in advance!

Regards,

Stefan

Hello Stefan,

you can use the method:

Value = Object.GetNextBinaryValue(eDataType)

eDataType

Aufzählung. Bestimmt den Datentyp des auszulesenden Werts. 2 - eI16 16-Bit-Integer. 3 - eI32 32-Bit-Integer. 4 - eI64 64-Bit-Integer. 5 - eByte Byte. 6 - eU16 16-Bit-Unsigned-Integer. 7 - eU32 32-Bit-Unsigned-Integer. 9 - eR32 32-Bit-Real. 10 - eR64 64-Bit-Real.

Hi Rebecca,

many thanks for your reply. Unfortunately, I think this doesn't help me because the data type I need would be "eI8". If I use eByte, the sign information is gone and if I use e.g. eI16, one byte to much is read.

Is there any other solution?

Anyway, thank you very much so far!

Regards,
Stefan

Hello Stefan,

with eI8 it should work. I will look that it will be corrected in our help!

Thanks,

Hi Rebecca,

thanks a lot! It works with data type eI8.

Obviously, I wasn't bold enough to just try! 😉

Kind regards,

Stefan
