C code

[Prince Boeing]

Hi All,

I have this checksum problem. Previously i am using C programming to do the checksum but since LabVIEW does not have a c code function (please correct me if i am wrong), i would need to convert/model it from C to LabVIEW model.

Say i have these few hexa values that i need to compute a checksum (81FF, 178B and 94) and the resulting checksum should be 65E2(hexa). I have tried the VIs of some of the past checksum posts but am unable to get the desired result.

Also, let's say the values that i need to compute a checksum are not of the same format, e.g 81FF(hexa) 1234(decimal), how can i go able to implement a checksum function for these two numbers?

Please help. Thank you.

hi prince boeing,

  If you have already used the c-program,why dont you convert to dll and use in labview?

Thanks and regards,

Hi srikrishnaNF,

Thank you for your advise. Will work on this direction.

shouldnt the sum be 9A1E?

Hi muks,

Yes the sum should be 9A1E. 0 - 9A1E will give me 65E2 which is the checksum that i want.

On the other hand, rather than 81FF 178B 94 which are all hexa, let's say my array inputs are 81FF 6027 (decimal) 148 (decimal), will i still be able to get the sum 9A1E?

Hi muks,

I have tried that but it does not give me the correct checksum.
