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. | |
|
|
Simulation |
|
|
Simulate Comms |
| No: Simulation is done using panel sliders. Yes: Send SPI data via API interface and show real time data using panel sliders. | |
