esp_get_error_string Report Error String
Synopsis:
#include “esp6000.h”
int esp_get_error_string(char *ErrorStr, long *ErrorNum, long *ServoTick)
Arguments: char ErrorStrg
string containing error message
long ErrorNum
error number
long ServoTick
servo cycle timestamp with 409
µ
sec. resolution
Library Location: \esp6000.dll
Description: esp_get_error_string() API function call reports ESP6000 error messages complete
with error string, error number, and timestamp. The ESP6000 queues error messages in
a 10-word FIFO buffer. The timestamp enables users to know the exact time of error
posting.
NOTE
ESP6000 uses a 10-word FIFO buffer to queue error messages.
Returns: ESPOK, ESPERROR
Hint: Check for errors after critical command sequences.
Usage Example:
#include “esp6000.h”
main()
{
long error, ServoTick;
double position;
char String[100];
if (!esp_init_system()) exit(-1);
esp_enable_motor(2); /* enable motor */
esp_move_absolute(2,-3.0); /* move stage */
while (!esp_move_done(2)); /* wait for move done */
/* prime the loop */
esp_get_error_string(String, &error, &ServoTick);
if(error == 0) return(0);
else printf(“Error: %s \r\n”, String);
while(error > 0)
{
esp_get_error_string(String, &error, &TickCount);
printf(“Error: %s \r\n”, String);
}
}
