Wierd gyro code problems...pls help

[Salik Syed]

Hi, i've coded a VERY simple code for a gyro ..... the gyro outputs 10bits so i shifted 2....but now the gyro stays at 135 even when not moving or being shaked etc... I can't figure out the problem...the gyro is working (we monitored voltage)

can you please read the code and help thank you

gyro1=rc_ana_in01;
2<<gyro1;
if(gyro1>136)
{
heading++;
}
if(gyro1<119)
{
heading=heading-1;
}


if(mode==1)
{

if(heading<turn+error) 
{
pwm01=184;
pwm02=70;
}
if(heading>turn-error)   //error is a tolerance!!!! i set it to 400
{
pwm01=70;
pwm02=184;
}
}

Thank You

btw we are using the BEI gyro from 2k3 (we know...its not allowed...we'll get another gyro soon)
