SE_LinearScanner()

int SE_LinearScanner	(	int	dir,
		long	rows,
		unsigned short int *	outBuffer,
		int	usbDevice
	)

With the optional module LINCAM-1 SESTILIO can be used to implement an image scanner. The optical module is based on SONY ILX553B, a linear CCD sensor of 5150 pixel (7um pitch).
To achieve maximum performance there are several constraints:
.

• Used A/D 0 on available inputs from 0 to 7
  
• Used motor output B.
  
• One step of the motor for one line sampled.
  

  Parameters

  dir	Motor direction for the scanning.
  rows	Number of rows for the sampled image.
  outBuffer	Image buffer. This buffer must be created according to the image dimension. The image is sampled at 16 bit an the image dimension is: 5150 * rows * 2
  usbDevice	Specify a SESTILIO USB identifier.

  Returns

  The number of steps still to be executed.

      mem = malloc(5150 * 1024 * sizeof(unsigned short int));
      // Acquire 1024 lines by 5150 pixel
      SE_LinearScanner(SE_MOT_DIR_CW, 1024, mem, 0);
      SE_Close(0);

refResistence	Reference resistance in mOhm
average	Number of samples for average.
usbDevice	Specify a SESTILIO USB identifier. // Four channel ammeter for(int i = 0; i < 4; i++) printf("I[%2d] = %5.3lf A\n", i, (double) SE_ReadCurrent(0, i, i + 4, 3, 0.1, usbDevice) / 1000.0);

Returns

The current value.

Parameters

adSource	Used A/D (0/1).
muxChan	Selected multiplexer channel.
average	Number of samples for average.
usbDevice	Specify a SESTILIO USB identifier. // Optional instruction SE_AuxPower(1, 0); // Turn on the power (+5V) on pin Y4.16 for DCDC converter // Read temperature (K) on 16 channels for(int i = 0; i < 16; i++) printf("CH[%2d] = %5.1lf K\n", i, (double) SE_ReadTemperature(i % 2, i % 8, 10, usbDevice) / 1000.0);

Returns

The temperature as milliKelvin.
