6.2 Implementation

 

The code for the driver can be split three section

• The buffer used to hold data read from the input channel but not yet read by HAPI.
• The interface to HAPI which reads the data from the buffer and controls driver operation.
• The driver that reads data from the input channel and adds it to the buffer.

Only the final section is dependent upon the actual data source with the buffer and HAPI interface code usable with almost any device.

• 6.2.1 The Buffer
• 6.2.2 The HAPI Interface
• 6.2.3 Data Capture
