Hi Everyone,
Recently I faced an interview question regarding Little-Big endians..
Does anyone of you know the answer for the same?
I am awaiting for your reply.
Thanks and regards,

Hi,
#So it means your hardware does not having any problem. what baud rate are you using to communicate with board? is it 9600bps?
# Please verify your flash magic SW supports windows 7 and are using latest version of it?
#You need to have a COM port listed in the Device Manager first...
Hi again,
ADC 10-bit conversion time ≥ 2.44 µs so the minimum value is 2.44 µs and might vary also.I suggest you to refer adc static characters.
I did not get your code fully:
while(T0TC<450000){ // Sampling
buf3[j]=read_adc(); // Sampling
j++...
Hello there,
Here I can not help you 100% regarding this concern.. But it may due to the delay occurring inside your CPU. If you come to ADC, Propagation delay, acquisition delay, holding time and sampling time delay, those can vary your total time of adc task. Also it dependents on your...
Hello there,
It dependents on how much acceleration range do you want to measure..? For a common use you can use 1g-6g accelerometers.

Hello ISPN,
Baud rate error may be because of your wrong hardware selection.
# Are you using 9600bps?
#Can you please manually check your USB-UART bridge ? short your TX-RX pin and try with hyper terminal?
Please update me.. if you can.

Hello lignin ,
Could you please explain what is this
If you want to toggle you pin use RB1=~RB1;
!= is a Relational Operator. please correct me if I am wrong.

Hi wilker ,
You can use any method as per your requirment ..
use timer for delay and hold.
Use external interrupt (button ), sleep and watchdog timer for turning on PIC.

Hi there,
Are you sure about this function look(v/10000);??
volt[0] = look(v/10000);
volt[1] = look((v/1000)%10);
volt[3] = look((v/100)%10);
current[0] = look(i/1000);
current[2] = look((i/100)%10);
current[3] = look((i/10)%10);
for current and voltage division...
Hi rangerskm ,
I hope its a local and global scope problem
try these..
#define MAXLINES 5000 /* max #lines to be sorted */
#define MAXLEN 1000 /* max length of any input line */
char *lineptr[MAXLINES]; /* pointers to text lines */
int getline(char *, int);
char...
