Irinos Measurement System
This function initializes a data transfer channel for dynamic measurement values.
Definition
MSC_STATUS
MSC_SetupExtendedDynamicChannel(
MSC_HANDLE Handle,
unsigned char OpCode,
unsigned char NumberOfSubChannels,
unsigned long SndBufferSize,
void* SndBuffer
);
Parameter
Handle
Device-Handle, which has been returned by a previous call of the function MSC_OpenDevice.
Opcode
The opcode of the dynamic measurement (opcRDM1 or opcRDM2).
NumberOfSubChannels
Number of measurement channels, which are transferred in a data frame (= number of measurement channels used for the dynamic measurement).
SndBufferSize
The size of the send buffer must be 1.
SndBuffer
Pointer to the send buffer. Minimum length is 1 byte. Its content is not relevant. It is only required to keep to the data structure.
Return value
If successful, MSC_STATUS_SUCCESS will be returned. In case of an error, an error code will be returned.
Comments
An extended dynamic measurement channel stores the data in several FIFO like buffers. The buffers are provided by the application with the function MSC_AttachSubChannelBuffer.
The measurement is running if a buffer is attached to all of the subchannels and these buffers are not full.
All measurement values have the data type 32 bit signed long. This also applies to measurement channels, which have a 16 or 8 bit value range.
