display float on 16x2 LCD in PIC 16F877 using Hi-tech C compiler

You need to write a little routine that converts a float to ascii..

Here is a very crass routine that does up to 7 digits..

Code:

void ftoa(float f,char *buf)
{
    int pos=0,ix,dp,num;
    if (f<0)
    {
        buf[pos++]='-';
        f = -f;
    }
    dp=0;
    while (f>=10.0) 
    {
        f=f/10.0;
        dp++;
    } 
    for (ix=1;ix<8;ix++)
    {
            num = f;
            f=f-num;
            if (num>9)
                buf[pos++]='#';
            else
                buf[pos++]='0'+num;
            if (dp==0) buf[pos++]='.';
            f=f*10.0;
            dp--;
    }
}
