Convert byte array to float

[aan928]

I have a byte array which I get from the sensor. I have manage to seperate the payload into three 4 sections. A and B and C are float values: A=+43.57, B=+1.88, C=-2.02. How may I proceed? I have tried type casting and converting to big endian. It doesnt work. Any ideas?

You are searching for FA but the attached VI with default doesnt contain FA.

Share us the data payload which you got and the expected decimal Value. will help you in converting using LabVIEW.

In my project everything is correct. I duplicated the file and have mistakenly typed AA in the field. It should be FA.

I hope i i did similiar conversion couple of years before, i rememeber i gave the reference for typecast is SGL instead of DBL.

Just have  a try.

Hi aan,

each part, consisting of 4 bytes, should be typecasted to a SGL value.

- Right now you typecast to DBL - FAIL 😄

- When the byte order is wrong you should use Reverse1DArray on those 4 byte-parts. Using SwapBytes/Words is wrong too…

- You can also use UnflattenFromString, which gives you the option to change the byte order for free…
