| Code: |
#include <16F876A.H>
#fuses HS, WDT, NOPROTECT, NOBROWNOUT, NOPUT, NOLVP , NOCPD , NODEBUG
#use delay(clock=8000000)
//#device adc=10
#include <Flex_LCD420_2.c>
//#include <ds1307.c>
//#include <2404_byme.c>
long j;
void WRITE_LONG_EXT_EEPROM(long int n, float data) {
int i;
for (i = 0; i < 4; i++)
write_eeprom(i + n, *((int8*)&data + i) ) ;
}
float READ_LONG_EXT_EEPROM(long int n) {
int i;
long data;
for (i = 0; i < 4; i++)
*((int8*)&data + i) = read_eeprom(i + n);
return(data);
}
void main()
{
//unsigned int i;
delay_ms(500);
lcd_init();
delay_ms(10);
WRITE_LONG_EXT_EEPROM(0,55.55);
while(1)
{
lcd_gotoXY(1,1);
printf(lcd_putc," %f", READ_LONG_EXT_EEPROM(0));
}
}

What's the result of that program.
i think it would be 55.55.
but it shows 24196.00
why??   |

Read the manual......
'Common questions and answers'
'How do I write variables to EEPROM that are not a byte'.
