<ul>

<li>cI2C is set to work on AVR targets only -> for other targets, you may use WireWrapper instead (will be using Wire) -> cI2C & WireWrapper libs declare same structures & functions as seen from the outside (switch between libs without changing anyhting but the include)</li>

|
|
</ul>
|
|
<p>v1.2 30 Nov 2017:</p><ul>

|
|
</ul>
|
|
<p>v1.1 29 Nov 2017:</p><ul>
|
|
<li>Frequency calculation fix (thanks to TonyWilk)</li>
|
|
<li>Set Frequency higher than Fast Mode (400KHz) will set bus to Fast Mode (frequency is up to 400KHz on AVR)</li>
|
|
<li>I2C_set_xxx now returns values applied, not bool</li>
|
|
</ul>
|
|
<p>v1.0 21 Nov 2017:</p><ul>
|
|
<li>Added const qualifier for function parameters</li>
|
|
<li>Return from comm functions if bytes to R/W set to 0</li>
|
|
</ul>
|
|
<p>v0.6 12 Jul 2017:</p><ul>
|
|
<li>compliance with Arduino v1.5+ IDE source located in src subfolder</li>
|
|
</ul>
|
|
<p>v0.5 31 Jan 2017:</p><ul>
|
|
<li>refactored I2C_SPEED enum names for coherence with I2C specifications</li>
|
|
<li>High Speed mode added in I2C_SPEED enum</li>
|
|
</ul>
|
|
<p>v0.4 23 Jan 2017:</p><ul>
|
|
<li>less inlines (less warnings)</li>

<li>inlines put into header (compatibility with WireWrapper)</li>
|
|
<li>other common code between cI2C and WireWrapper changes</li>
|
|
<li>README.md updated to tell about WireWrapper library</li>
|
|
</ul>

|
|
<li>I2C_sndAddr function parameters changed</li>
|
|
<li>added I2C_uninit function to release i2c bus</li>
