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.
axis
Allowed values:
Value | Description |
|---|---|
ADC_INPUT_AD0 | First ADC-Channel |
ADC_INPUT_AD1 | Second ADC-Channel |
ADC_INPUT_AD2 | Third ADC-Channel |
ADC_INPUT_AD3 | Fourth ADC-Channel |
ADC_INPUT_TSPX | Touch: X-Axis P |
ADC_INPUT_TSMX | Touch: X-Axis M |
ADC_INPUT_TSPY | Touch: Y-Axis P |
ADC_INPUT_TSMY | Touch: Y-Axis M |
samples
Number of samples to get.
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.
