<h1 id="purpose">Purpose</h1>
<p>Touch Sensor is use in a one of HMI (Human Machine Interface).</p>
<p>Instead of using mechanical switch, using the finger touch on the surface.</p>
<p>STM32 Touch Sensing Library, TSL, is used to support Touch Sensors with:</p>
<ul>
<li><p>Touch Sensing Controler or TSC on:</p></li>
<ul>
<li><p>STM32L0, STM32L4, STM32F0, STM32F3, STM32WB</p></li>
</ul>
<li><p>Touch Sensing hardware assist on:</p></li>
<ul>
<li><p>STM32L1</p></li>
</ul>
</ul>
<p>TSC and TSL overview:</p>
<ul>
<li><p>TSC is based on charge transfer mechanism:</p></li>

<ul>
<li>Use of Linear/Rotary sensors with STM32L1xx High-density devices:</li>
<ul>
<li>The hardware acquisition is too noisy to properly support Linear/Rotary sensors.</li>
<li>This noise induces an important jitter of the reported position.</li>
<li>As a workaround, the position resolution must be configured to 4 bits maximum.</li>
<li>The Touchkey sensors are not impacted by this issue.</li>
</ul>
