◆ SE_FastReadAnalog()

int SE_FastReadAnalog	(	int	source,
		int	trigger,
		unsigned	period,
		int	samples,
		int	usbDevice
	)

Start a buffered sampling with one or two A/D converters. Sampled data is stored into RAM 0.

Parameters

source	Set which A/D is used for sampling. 0 = AD0, 1 = AD1, 2 = AD0 and AD1. A/D Selection
trigger	Set requested trigger mode. 0 = No trigger, 1 = INTA, 2 = INTB, 3 = P4.6 Low, 4 = P4.6 High, 5 = P4.7 Low, P4.7 High. Trigger source
period	Set the sampling period in the range 1 to 1E8 us.
samples	Set the number of samples to be acquired, accepted range is 1 to 16384 but with source 2 (AD0+AD1) maximum number of samples is 8192. With source = 2 this number is the total amount.
usbDevice	Specify a SESTILIO USB identifier.

#include "sest.h"
if(SE_Open('0', 0) == SE_S_SUCCESS)
{
unsigned short int mem[1024]; // Storage area for sampled data
SE_SetMux(0, 0); // Set channel 0 on AD0
SE_FastReadAnalog(0, 0, 2, 1024, 0); // Grab 1024 samples from AD0 @ 500KHz
SE_GetSampleData(SE_RAM_0, 0, 1024, mem, 0); // Get sampled data
// Dump sampled data
for(int i = 0; i < 1024; i++)
printf("[%04d] = %6.3lfV\n", i, SE_ADV((double) mem[i]));
SE_Close(0);
}

Returns: Operation status. Operation Status
