2. Example of using the event controller
The following example shows how to configure the event controller to synchronize analog input
operation between two devices using the synchronization connector.
Synchronizing between two devices is performed by connecting control signals from device 1 to
device 2.
1
Set the analog input start condition (Device 1)
This example specifies software activation.
2
Setting up the event controller (Device 1)
Setup the event controller to connect the software start signal to the synchronization
connector for output to device 2.The signal destination is synchronization bus master signal 1
and the signal source is the analog input software start signal.
3
Set the clock to use for analog input (Device 1)
This example specifies the internal clock.
4
Setting up the event controller (Device 1)
Setup the event controller to connect the internal clock to the synchronization connector for
output to device 2.
The signal destination is synchronization bus master signal 2 and the signal source is the
internal clock signal for analog input. Device 2 performs analog input in accordance with the
control signals received from device 1.
5
Set the analog input start condition (Device 2)
As the control signal from device 1 is used as the start condition, set this as an output from the
event controller.
6
Setting up the event controller (Device 2)
The software start signal from device 1 is connected to synchronization bus master signal 1
which in turn is connected to synchronization bus slave signal 1 in the synchronization
connector.
Accordingly, setup the event controller to use synchronization bus slave signal 1 as the
conversion start signal for device 2.
The signal destination is the conversion start signal for analog input and the signal source is
synchronization bus slave signal 1.
7
Set the clock to use for analog input (Device 2)
As the control signal from device 1 is used as the clock, set this as an output from the event
controller.
