|
ContinuousMeasurement |
| Powers up and starts the continous measurement mode. Delays in between measurements readings must be provided by the user, | |
 - BYTE
|
Resolution |
| 0=1lx (120ms) / 1=0.5lx (120ms) / 2 = 4lx (16ms) | |
 - VOID

Return |
|
|
OneTimeMeasurement |
| Powers up and starts a single measurement before returning to power down mode. Waits for the measurement to be ready and returns the value. | |
| - BYTE
|
Resolution |
| 0=1lx (120ms) / 1=0.5lx (120ms) / 2 = 4lx (16ms) | |
 - UINT

|
Stop Delay |
| On older microcontroller devices there is a potential for the I2C hardware channel to lock up if there is not a 10ms delay between an I2C stop event and the next I2C start event. Most modern microcontrollers will not have a problem so this property can be disabled to speed up the I2C communications. | |

Simulation |
|
|
Simulate Comms |
| Allows the simulation data to come from the panel GUI or relayed via an injector component. | |
