ADC_Sample

The function ADC_Sample gets samples of the analog voltage-value measured by the UCB1400-Controller on the Trizeps-Module.

int ADC_Sample( unsigned short * sample, unsigned short axis, int samples ); int sampleADC( unsigned short * sample, unsigned short axis, int samples );

Parameters

sample
Pointer of the variable, that receives the measured sample.

Return Values

If the function succeeds, the return value is 1.

If the function fails, the return value is -1.

Remarks

This function uses the AC97-Link functions. So you have to use AC97_Alloc before calling this function. Keep in mind you must protect the access to the AC97-Link! If you just want to read the ADC-values from AD0 to AD3, it is recommend to use ADC_Read. View UCB1400-Datasheet for details.

Requirements

OS Versions: Windows CE 4.2 and later.
