Yes ... Post the program you are having difficulty with.

Also post a link to the datasheet for the scales you are trying to work with.

...R Serial Input Basics - simple reliable non-blocking ways to receive data.

thanks for reply

here is the interface manual of the scale
but the code im using is just reading serial data & print on lcd

However simple it seems you need to post the program. The devil is in the detail.
