SampleADC |
| Performs a single ADC sample and returns the result as a 24-bit value | |
 - BYTE
|
PositiveChannel |
| 0=CH0 - 7=CH7, 8=GND, 9=VDD, 11=REF+, 12=REF-, 13=TP, 14=TM, 15=VCM | |
| - BYTE
|
NegativeChannel |
| 0=CH0 - 7=CH7, 8=GND, 9=VDD, 11=REF+, 12=REF-, 13=TP, 14=TM, 15=VCM | |
| [[File:]] - | Return |
|
|
Initialise |
| Confgures the SPI bus ready for communications and initialises the MCP356X device. Returns true if device is responding to commands. | |
 - BOOL
|
Return |

Device Type |
|
|
Device Address |
| These bits are fixed from the manufacturer and by default are 01. Used as Bits 6 and 7 of the command byte. Alternative bits must be requested from the manufacturer. | |

|
ADC Bias Current |
|
|
AMCLK Prescaler |
|
|
Oversampling Ratio |
|
|
ADC Gain |
|
|
IRQ Mode |
|
Scope Traces |
| Selects if the scope traces are automatically generated or not | |
|
|
Console Data |
| Selects if the console data is automatically generated or not | |
|
|
API |
| Selects the API Slave to use to send and receive real world SPI data during simulation. | |
|
Connections |
|
|
Channel |
| SPI Channel selector | |
|
|
Prescale |
| Prescale option selector | |
|
MOSI |
| SPI Data Out Pin SDO - Also Known as Master Out Slave In (MOSI) when used in Master mode. | |
|
|
MISO |
| SPI Data In Pin SDI - Also Known as Master In Slave Out (MISO) when used in Master mode. | |
|
|
CLK |
| SPI Clock Pin CLK - The Clock signal is driven by the SPI master. | |
|
|
CS / SS |
| Chip Select / Slave Select Pin Master Mode: General purpose output pin used to select the remote SPI device. Slave Mode: Hardware chip select pin input used to select the SPI device. | |
|
|
Use IRQ |
| No: Use polling of the status register to determine when an ADC sample is complete. Yes: Use the IRQ interrupt pin to determine when an ADC sample is complete. | |
|
|
IRQ Pin |
| Connected to the IRQ pin of the device, goes low on an interrupt event such as sample complete. | |
|
|
Simulations |
|
|
Simulate Comms |
| No: Simulation is done using panel sliders. Yes: Send SPI data via API interface and show real time data using panel sliders. | |
