Input ADC component
Allows the values from a buffer to be assigned driectly from an analog enabled pin. Either a single sample at a time or a number of samples. Auto scales the digital value to fill the entire range of the specified buffer type.

|
AddSample |
| Adds a single ADC sample to the current location in the specified buffer. If Auto Scale is enabled then the sample will be scaled to correctly fit inside the buffer. Auto increments current location. | |
 - VOID
|
Return |
|
|
AddSampleArray |
| Adds a single ADC sample to the current location in the specified buffer. If Auto Scale is enabled then the sample will be scaled to correctly fit inside the buffer. Auto increments current location. | |
 - UINT
|
SampleDelay |
| Number of us in between each sample. | |
| - VOID
|
Return |

Properties |
|
Buffer Size |
| Number of individual elements the buffer can store, default 1. | |
|
Buffer Type |
| Sets the buffer data type, data is automatically scaled to fit and make full use of the data type. | |
|
Connections |
|
Channel |
| Analogue Input Channel - Which pin is the analogue input connected to? | |
|
|
Settings |
|
Auto Adjust Scale |
| Yes: Automatically convert ADC samples to match the full bit depth of the DSP buffer. No: Leave the ADC samples at the native bit depth. | |
|
|
VRef option |
| Defines what is used as the ADC maximum reference. ADC Range = GND to VRef Voltage VDD - Defines the microcontrollers power supply pin as the max reference, VREF+ Pin - Dedicated pin on the microcontroller to allow for a variable reference voltage. | |
|
|
Conversion speed |
| Clock setting to select how fast the ADC peripheral will perform an ADC conversion. The FRC setting is based on a RC time base and so will vary with temperature and pressure. Other settings are generally based on divisions of the master clock. | |
|
Acquisition cycles |
| Number of micro seconds to wait for the ADC input to charge before starting the analogue sample. | |
|
|
Bit Depth |
| Maximum number of digital bits the ADC can sample. 8 bit = ADC range 0 - 255 10 bit = ADC range 0 - 1023 12 bit = ADC range 0 - 4095 | |
