i declare my global as below
typedef struct
{
float rdata;
float tdata;
} MyChangeListType;
static MyChangeListType MyChangeArray[10];
Now for how to use it:
1.At the startapp, i get data from database to array .
2.And there is only one procedure i modify the array and then save the
modify to database , but mostly i did not run that procedure .
more often ,i get the data from the RS232 , then change the RS232 data to
another array using MyChangeArray .
There is the trouble:
in my program i find that at the startapp ,data in MyChangeArray is
correct
,but when i use them to change the RS232's data , they are not same as at
be startapp procedure ,and at that time i have not modified MyChangeArray.
