HI,
I have a problem with WinAVR-20060421.
I am writing a program ,using avr-gcc (GCC) 3.4.6 /atmega128£¬when I
compile it ,it occur errors!!
There are some codes in my program below:
---------------------------------------------------------------
#define ADC_PRE 0
#define ADC_RH 1
#define ADC_TEMP 2
#define ADC_OIL 3
......
unsigned int ADC_result;
signed int OIL_value;
signed int PRE_result;
signed int RH_result;
signed int TEMP_result;
unsigned int tt0,Xt,Xt0,XRH1,XRH2;
......
unsigned int read_adc(unsigned char adc_input)
{
ADMUX=(0x40|adc_input);
ADCSRA|=(1<<ADSC);
loop_until_bit_is_set(ADCSRA,ADIF);
ADCSRA|=(1<<ADIF);
return ADC;
}
void get_AD(void)
{
float float_tmp;
ADC_result=read_adc(ADC_RH);
float_tmp=(long)ADC_result*Vref;
float_tmp=float_tmp/1024;
float_tmp=float_tmp*XRH1;
float_tmp=float_tmp*0.0032;
float_tmp=float_tmp-XRH2;

if(RH_result>999) RH_result=999;
if(RH_result<0) RH_result=0;
ADC_result=read_adc(ADC_TEMP);
float_tmp=(long)ADC_result*Vref;
float_tmp=float_tmp/1024;
float_tmp=float_tmp*Xt0;
float_tmp=float_tmp/1000;
TEMP_result=(signed int)(float_tmp-2730);//////////// #B
if(TEMP_result>1250){TEMP_result=1250;}
if(TEMP_result<-250){TEMP_result=-250;}
ADC_result=read_adc(ADC_OIL);
float_tmp=(long)ADC_result*Vref;
float_tmp=float_tmp/1024;
if((float_tmp-tt0)>0) float_tmp=float_tmp*0.64;
else float_tmp=float_tmp*0.71;
float_tmp=float_tmp*Xt;
float_tmp=float_tmp/1000;
if(float_tmp> 1250) float_tmp=1250;
if(float_tmp< -250) float_tmp=-250;

{
disp_real_data();
}

And then I do some modification respectively,it gets different result:
A) If I only delete the line marked with #A , and compile it again ,it
compile successfully.
B) If I only delete the line marked with #B , and compile it again ,it also
occur errors!

£££££££££££££££££££££££££££££££££££
So, I have some questions:
a. float_tmp is "float" type variable,OIL_value,PRE_result,RH_result and
TEMP_result are "signed int" type variable,is there something wrong in my
codes about change of variable each other?
b. messages of compiler
"C:\DOCUME~1\Aminis~1\LOCALS~1\Temp/ccOCaaaa.s:XXXXX: Error: value of XXXXX
too large for field of 2 bytes at XXXXX",why the value of XXXXX are not the
same of A),B),C),D),E),F) above.
c. My codes are very big, but it is just about 70 of 128K!!
And I use a array with about 10000 Elements of char (1 Bytes) has 10000
kytes stored as const data in PROGMEM. I define these large arrays store in
FLASH,such as :
const unsigned char c16x16[] PROGMEM={
0x02,0x00,0x01,0x00,0x01,0x04,0xff,0xfe,0x00,0x10,0x1f,0xf8,0x10,0x10,0x10,0x10,
0x10,0x10,0x1f,0xf0,0x01,0x00,0x09,0x40,0x09,0x30,0x11,0x18,0x25,0x08,0x02,0x00,
......
......
0x02,0x10,0x22,0x18,0x24,0x16,0x44,0x12,0x08,0x10,0x10,0x10,0x20,0x50,0x40,0x20,
0x02,0x00,0x42,0x0c,0x32,0x70,0x12,0x40,0x8f,0xc0,0x62,0x44,0x22,0x7e,0x0a,0xc8};
//c16x16 total 10752 elements
If I want to access the progmem data which are located above the 64kByte,
is it limit? Is these make errors happened?
d. How to know what's at the lines the assembler is complaining about?
Waiting for your reply!
And Wish you,Merry Christmas!
Thanks,
JimStation
