In this code I read the 6 analog inputs for 1 hour and stored it in text file in flash.
I get the text file like this with 60 datas.
1: 1300971050,2.175,2.174,2.176,2.169,2.177,2.168
I need to read this analog.txt file. I am using UART to send this data.
How can I read and send? Kindly help me...
void read_analog()
{
FILE *fp = fopen("/local/analog.txt","w");
while (count < 60) {
avg[0] = (float)ain_UseA.read_u16()* vdiv;
avg[1] = (float)ain_UseB.read_u16()* vdiv;
avg[2] = (float)ain_UseC.read_u16()* vdiv;
avg[3] = (float)ain_UseD.read_u16()* vdiv;
avg[4] = (float)ain_UseE.read_u16()* vdiv;
avg[5] = (float)ain_UseF.read_u16()* vdiv;
uint16_t temp;
uint8_t i;
for(i=2;i<8;i++)
{
temp = avg[i-2] * 1000;
payload[(i * 2)] = temp >> 8;
payload[(i * 2) + 1] = temp;
payload_len += 2;
}
payload_len = 16;
payload[0] = seconds >> 24;
payload[1] = seconds >> 16;
payload[2] = seconds >> 8;
payload[3] = seconds;
fprintf (fp, "%3i:%d,%5.3f,%5.3f,%5.3f,%5.3f,%5.3f,%5.3f\r\n", count+1,seconds,avg[0],avg[1],avg[2],avg[3],avg[4],avg[5]);
uart_PC.printf("Time:%d,S1:%5.3f,S2:%5.3f,S3:%5.3f,S4:%5.3f,S5:%5.3f,S6:%5.3f\r\n",seconds,avg[0],avg[1],avg[2],avg[3],avg[4],avg[5]);
count++;
wait(60);
}
fclose(fp);
}
