how does the software repetier calculate the checksum

Hi everybody

I am facing a problem.
I can generate de g code but I can´t recognize the checksum number
We are using PIC but we can´t calculate the checksum number
As we are developing a graduate work we can´t use arduino
Could anyone make me sure how checksum figures out
Could anyone help us

thanks a lot

See the g-code explanation in the reprap wiki. There the checksum is explained.
But it very simple. XOR all bytes of the command and then add * to your code.
