Multi Device Handling for TDC devices.
These functions allow to access multiple TDC devices at the same time from one program. The functions are alternatives to TDC_init and TDC_deInit.
Use TDC_discover to find the connected devices and TDC_getDeviceInfo inspect them. A control connection to a device can be established with TDC_connect. Use TDC_addressDevice to address the following commands to a specific connected device. To terminate the session, disconnect all devices using TDC_disconnect (TDC_deInit does that job also).
Definition in file tdcmultidev.h.
Address a Device.
Selects a device as the target of the following function calls. All functions are affected that don't have a device number as input parameter.
| devNo | Number of the device to address, 0 ≤ devNo < devCount. |
Connect to a Device.
Establishes a connection to the selected device. This is a precondition for all function calls that affect that specific device, in particular for TDC_addressDevice. The call implicitly addresses the device.
| devNo | Number of the device to connect to, 0 ≤ devNo < devCount. |
Disconnect from a Device.
Closes the connection to the selected device. If the device was adressed, a new address has to be set (TDC_addressDevice). To disconnect from all devices at the same time, TDC_deInit can be used.
| devNo | Number of the device to disconnect from, 0 ≤ devNo < devCount. |
Find Devices.
Initializes the library and searches for connected TDC devices. All existing device connections are closed.
The function is a precondition for all other function calls. Found devices can be inspected with TDC_getDeviceInfo and connected by TDC_connect. This procedure it is meant as an alternative to TDC_init.
| devCount | Output: Number of devices found |
Current Device Address.
Retrieves the number of the currently addressed device. Returns error if no device is connected.
| devNo | Output: Number of the addressed device |

| TDC_DevType * | type, | ||
| int * | id, | ||
| char * | serialNo, | ||
| Bln32 * | connected | ||
| ) |
Inspect a Device.
Returns some informations about a device that has been found by TDC_discover. The device doesn't have to be connected. The pointers to the output variables may be NULL to ignore the value.
| devNo | Number of the device to inspect, 0 ≤ devNo < devCount. |
| type | Output: Type of the device |
| id | Output: Device ID as programmed by the user |
| serialNo | Output: Serial number of the device. The string buffer must be at least 16 bytes long. |
| connected | Output: If the device is connected by TDC_connect |
