PIC chip serial variables

Ive been trying to take in serial data from a PIC chip, which is working, but for some reason, I cant use that data really as a variable. Right now I have a pressure sensor working, and Processing spits out the correct pressure values when I have it print ln, but when I try to set even a simple variable, like x coordinates or even bg color, the program just seizures and doesnt really go anywhere. I just took the built in program for analog input and added a variable for background. heres the code:
String buff = "";
int val = 0;
int NEWLINE = 10;
void setup()
{
size(200, 200);
beginSerial(9600);
}
void loop()
{
}
void serialEvent()
{
if(serial != NEWLINE) {
buff += char(serial);
} else {
buff = buff.substring(0, buff.length()-1);
background(val);
val = Integer.parseInt(buff)/4;
println(val);
buff = "";
}
}
Any Ideas?
