6.1.4.2
EZURiO supplies a range of audio codec evaluation boards to allow rapid development of audio
applications.
Order Numbers for these boards are:
6.1.5
The BISM II PA provides access to two 8-bit ADCs. These provide an input range of 0mV to 1,800mV,
which can be read using the S registers 701 and 702.
Suitable external scaling and over-voltage protection should be incorporated in your design.
module provides 5 samples per second at the UART with a baud rate of 115,200 or above.
Low latency access of the upper 6 bits of the ADCs can be obtained by using EZURiO’s I/O via an
enhanced inquiry process.
7. Integrated Firmware
7.1
The BISM II PA has been designed to provide the fastest route to market for designers who wish to
use Bluetooth to wirelessly enable their products. To achieve this EZURiO has implemented a wide
ranging set of AT commands that control all of the standard Bluetooth tasks.
complexity of Bluetooth from the design engineer and allow the wireless link to be controlled by
means of a simple set of commands.
For applications where multiple concurrent live connections need to be maintained a variant of
firmware is available which is specifically targeted at multipoint operation.
For both applications a comprehensive range of windows based software is available to speed up the
design process. A low cost development kit is also available that can be used for prototyping both
cable replacement and multipoint applications.
7.2
Bluetooth has been designed to accommodate a very wide range of wireless applications. To enable
these different applications the Bluetooth SIG (Special Interest Group) has defined a series of
different profiles that define the way in which Bluetooth devices communicate with each other and
perform basic functions.
scenarios, upon which more complex user applications can be developed.
There are over 30 different profiles, many of which have been developed for specific applications.
The BISM II PA firmware is provided with support for the profiles that are most commonly required
for cable replacement applications.
The current profiles supported by the AT command set firmware (point to point applications) include:
