esp_get_all_adc Read All Analog-To-Digital Converter Channels
Synopsis:
#include “esp6000.h”
int esp_get_all_adc(float *DataArray, long *timestamp)
Arguments:
float DataArray
address of array where ADC data is to be stored
long timestamp
current servo counter value at time of acquisition
Library Location:
\esp6000.dll
Description:
esp_get_all_adc() reads all analog-to-digital converter channels 1-8.
The analog input range of each ADC channel is software-configurable for ranges of
±
10V,
±
5V,
±
2.5V, and
±
1.25V.
ADC channels are located on the analog I/O connector on the controller card.

float DataArray[8];
if (!esp_init_system()) exit(-1);
/* Set ADC Gain */
esp_set_adc_gain(V10);
/* Set ADC Range */
esp_set_adc_range(UNIPOLAR);
/* Acquire All ADC Channels Data */
esp_get_all_adc(DataArray, ×tamp);
}
