The only differences will be found in the calling convention of the functions. For precise details, please refer to the Philips I 2 C specification. Add to watch list Remove from watch list. The function will block for the specified timeout. For additional information, see the Global Shipping Program terms and conditions – opens in a new window or tab.

If the number of bytes written is zero, the following conditions are possible. Since a new Aardvark DLL can be made available to an already compiled application, it is essential to ensure the compatibility hsb the Rosetta binding used by the application e.

The topmost bits are ignored. The phase option determines whether to sample or setup on the leading edge.

Read a stream of bytes from the I 2 C slave device. As the buyer, you should be aware of possible: That byte was dropped.

The Aardvark will always receive the same number of bytes that uzb sends out barring any error. If the slave has fewer bytes to transmit than the number requested by the master, the slave will simply stop transmitting and the master will receive 0xff for each remaining byte in the transmission.


Similarly, if the Aardvark I 2 C subsystem was placed into slave mode and in the middle of a slave transaction, this command will disconnect the slave from the bus, flush the last transfer, and re-enable the slave. Eventually an I 2 C transaction must be issued without the “no stop” option so that a stop condition is issued and the bus is freed.

There is no support for the hardware address programming feature of the general call that is described in the I 2 C protocol specification since that capability is not needed for Aardvark devices.

If a timeout value outside this range is passed to the API function, the timeout will be restricted. Because all communication takes place on only two wires, all devices must have a unique address to identify it on the bus.

Total Phase Aardvark I2C/SPI Host Adapter

Otherwise, the Aardvark adapter will simply return the data it just received. In the worst case scenario, a corruption can cause the Aardvark adapter to be locked until a subsequent clean update is executed.

There was an error reading the acknowledgment from the Aardvark adapter. The clock would then transition low-to-high on the leading edge and high-to-low on the trailing edge. This configuration is held as long as the slave mode is enabled see the API documentation later in the manual. Please note that these steps will make the entire USB filesystem world writable.


The transmission of bytes from the Aardvark slave, when it is configured as an I 2 C slave, is asynchronous with respect to the PC host software. Most of the Aardvark API functions can return a status or error code back to the caller. A logic high of 3. Enable the Aardvark adapter as an I 2 C slave device. aardvagk

See all wuweiqi has no other items for sale. This can be inefficient in simple configurations and a direct-link interface such as SPI might be preferred. Why is this review inappropriate?

For precise details, please refer to the Philips I 2 C specification. Learn more about SPI in the article. How does this work? Please see the Philips specification for more details. The complete list of status codes is provided at the end of this chapter. This behavior is in accordance with the I 2 C protocol. Likewise, each firmware version is tagged as being compatible with DLL revisions greater than or equal to a specific version number.
