|
||
|
|
<p>This API supports 7-bit and 10-bit addresses. Traits feature an <code>AddressMode</code>
|
||
|
|
marker type parameter. Two implementation of the <code>AddressMode</code> exist:
|
||
|
|
<code>SevenBitAddress</code> and <code>TenBitAddress</code>.</p>
|
||
|
|
<p>Through this marker types it is possible to implement each address mode for
|
||
|
|
the traits independently in <code>embedded-hal</code> implementations and device drivers
|
||
|
|
can depend only on the mode that they support.</p>
|
||
|
|
<p>Additionally, the I2C 10-bit address mode has been developed to be fully
|
||
|
|
backwards compatible with the 7-bit address mode. This allows for a
|
||
|
|
software-emulated 10-bit addressing implementation if the address mode
|
||
|
|
is not supported by the hardware.</p>
|
||
|
|
<p>Since 7-bit addressing is the mode of the majority of I2C devices,
|
||
|
|
<code>SevenBitAddress</code> has been set as default mode and thus can be omitted if desired.</p>
