For information on how to integrate the bindings for other languages, please see the example code included on the distribution CD and also available for download on the Total Phase website.
Since a new Aardvark DLL can be made available to an already compiled application, it is essential to ensure the compatibility of the Rosetta binding used by the application e. The above situation will pass the appropriate version checks.

The compatibility check is performed within the binding. While provided language bindings stubs are fully functional, it is possible to modify the code found within this file according to specific requirements imposed by the application designer. For example, in the C bindings one can aardvark i2cspi host adapter the DLL search and loading behavior to conform to a specific paradigm. See the comments in aardvark.
There is buffering within the Aardvark DLL, on a per-device basis, to help capture asynchronous messages. Take the case of the Aardvark adapter receiving I 2 C messages asynchronously. If the application calls the function to change the SPI bitrate while some unprocessed asynchronous messages are pending, the Aardvark adapter will transact the bitrate change but also save any pending I 2 C messages internally. The messages will be held until the appropriate API function is called. The buffers are only used when an Aardvark API call is invoked. The buffer size is adequate since the overall limitation for asynchronous messages is fundamentally determined by the operating systems internal buffer size. This concept is explained below.
A slave can receive messages asynchronously with respect to the host PC software. Between calls to the Aardvark API, these messages must be buffered somewhere in memory. This is accomplished on the PC host, courtesy of the operating system. Naturally the buffer is limited in size and once this buffer is full, bytes will be dropped. An overflow can occur when the Aardvark device receives asynchronous messages faster than the rate that they are processed — the receive link is saturated. This condition can affect other synchronous communication with the Aardvark adapter. For example, if the SPI slave is receiving many unserviced messages messages left pending in the operating systems buffera subsequent call to change the bitrate of I 2 C could fail in the following manner. The requested bitrate has most likely been set by the Aardvark device, but the response was lost.
A similar problem can happen when one attempts to disable the very slave that is saturating the incoming receive buffer! The API function sends a command to disable the slave, but the acknowledgment from the Aardvark adapter is lost. The API call will aardvark i2cspi host adapter this as a communication error, but if the slave was actually disabled, a subsequent call to disable the slave should complete without errors.
The receive saturation problem can be improved in two ways. The obvious solution is to reduce the amount of traffic that is sent by the master between calls to the Aardvark API.

This will require the ability to reconfigure the offending master device. The other option is to more regularly poll the slave to obtain any pending asynchronous messages.
Keep in mind aardvark i2cspi host adapter each call to capture pending asynchronous data can have a timeout of up to ms. If there is other time critical code that must be executed simultaneously, it is best to use the asynchronous polling function found in the API which allows for variable timeout values.
The Aardvark DLL is designed for single-threaded environments so as to allow for maximum cross-platform compatibility. If the application design requires multi-threaded use of the Aardvark functionality, each Aardvark API call can be wrapped with a thread-safe locking mechanism before and after invocation. A call to any Aardvark API function that communicates with the host aardvark i2cspi host adapter will also fetch any pending asynchronous messages, buffering them for subsequent calls to the asynchronous slave receive functions.

This is caused by the inherent design of the USB architecture. The best throughput can be achieved for single transactions that transfer a large aardvark i2cspi host adapter of bytes at a time.Aardvark I2C/SPI Host Adapter is a fast and powerful I2C bus and SPI bus host adapter via USB.
