2's complement

[PaulMc]

Hi anyone got any nice ways of converting 12bit 2's complement into its decimal format?

Hello Paul,

I hope, I that I understood right.

The VI in the attachment creates the 2´s complement and shows the decimal value. It´s for 8 bits.

Hello PaulMc,

here is my solution to converting 12 bit Two's complement to decimal.

I hope I did not make any faults 🙂

Hi,

Here is my solution.

Hello Xu,

your solution seems to have problems with negative numbers...

I included a similar method to yours in my example.

Hi guys

GerdW your solution worked best.

My own solution had a problem with 0x800, it would equal 0 and not -2048, but all other values worked.

Cheers

Hi guys,

one more try - dac12bit.vi............ - used as sub.vi  for  12 Bit ADC  MAX168 

with possibility to decide, if the IC is used in unipolar or bipolar mode. 

Find it in Diagram of MAX168.vi   ( controlled via LPT - Port ).

Hi GerdW,

You are right, My vi was wrong. I forgot to set the default values of the "32-bit" controls on the frontpanel to FALSE.

Try this corrected one, please. Hope no error this time.
Thank you,
Xu

Did I modify this correctly to work with 16 bits?

sorry Christian,

if you would send your code again ....- with   LV 7.1 code attached

not everybody around has already upgraded to LV8
