Tool/software: TI C/C++ Compiler
Dear all,
I have work on a new project that needs SD16 to convert analog data to digital data.
In order to get the data with the lowest tolerance scope, I do SD16 for many times and get average.
In the process, I define a temporarily variable with the format unsigned long, and the variable is used or saving the result of SD16MEM.
After the process is finished, I get the average of the temporarily variable into times of getting SD16.
My trouble is that if the times(define as SD16_Check_Time in the code) is higher the 40, MSP will reboot in the process of SD16.
What is the reason that cause the status?
If I still need a lot of times to do this operation, how can I solve the problem?
This is the code I use for get SD16,
#define SD16_Check_Time 30
void Get_SD16_Data(void)
{
unsigned long temp_AD_Value;
unsigned int temp_SD16;
unsigned short loop;
temp_AD_Value=0;
for(loop=0;loop<SD16_Check_Time;loop++)
{
SD16CCTL0 = SD16SNGL + SD16SC;// Set bit to start conversion
while ((SD16CCTL0 & SD16IFG)==0);// Poll interrupt flag for CH0
temp_SD16=SD16MEM0;// Save CH0 results (clears IFG)
temp_AD_Value += temp_SD16;
}
AD_Value=temp_AD_Value/SD16_Check_Time;
}
Sincerely,
Yu-Chuan, Chen
