# Title: Force 4 Click Board™


## Description: How Does The Force 4 Click Board™ Work? The Force 4 Click Board™ work in the same way as our air (atmospheric) pressure sensors, using the piezoresistive method. They detect loads (force) with a piezoresistive element manufactured using MEMS processes. Force sensors differ from air pressure sensors in that they have a thicker diaphragm, allowing detection of only relatively large changes in pressure, like from loads, while very subtle fluctuations, such as changes in air pressure, do not affect the output. Force 4 Click utilizes an additional IC. It uses the MCP3221, a 12-bit successive approximation A/D converter (ADC) with I2C Interface, from Microchip. It is used to sample the output voltage from the sensor, providing data for the microcontroller (MCU) or some other device capable of communicating over the I2C bus. The voltage is sampled to a 12-bit value using the MCP1101-33 as the voltage reference. If analog voltage is preferred to be red directly by the MCU, it can be easily done by adding 0 ohm resistor on J1 marked position on PCB, and the sensor output voltage will be available for reading on AN pin of mikroBUS™. The Force 4 Click Board™ features the smallest force sensors in the industry with dimensions compact enough which makes it a perfect solution for developing a fine-diameter stylus pen.

- amazon_short_description: The Force 4 Click Board™ Board is based on HSFPAR003A piezoresistive force sensor from Alpsalpine. This product is a force sensor using the effect of a piezoresistive bridge circuit formed on silicon diaphragm. Piezoresistive force sensors achieve higher linearity than other force sensors. To help with stability and accuracy Force 4 Click Board™ also includes MCP1101-33 a high precision buffered voltage reference as a power supply to a force sensor that allows high stability and accuracy of output voltage readings.

<p>We provide a library for the <strong>Force 4 Click Board™</strong> on our LibStock page, as well as a demo application (example), developed using MikroElektronika compilers. The demo can run on all the main MikroElektronika development boards.</p>

<h3>Library Description</h3>

<p>Library provides function for reading raw ADC data from device.</p>

<h4>Key Functions</h4>

<ul>
	<li><code>uint16_t force4_read_adc( void )</code> - Reading raw 12 bit ADC data</li>
</ul>

<h3>Example Description</h3>

<p>The application is composed of three sections :</p>

<ul>
	<li>System Initialization - Initialization of I2C communication</li>
	<li>Application Initialization - Mapping pins on selected MIKROBUS</li>
	<li>Application Task - Every 100ms read 12bit adc value from dev</li>
</ul>

<pre>
void application_task ( )
{
 uint16_t adc_val;
 char demo_txt[ 30 ] = "";
 adc_val = force4_read_adc( );
 WordToStr( adc_val, demo_txt );
 mikrobus_logWrite( "-ADC: ", _LOG_TEXT );
 mikrobus_logWrite( demo_txt, _LOG_LINE );

 Delay_ms( 100 );
}
</pre>

<p>The full application code, and ready to use projects can be found on our LibStock page.</p>

<p>Other mikroE Libraries used in the example:</p>

<ul>
	<li>Conversions</li>
	<li>I2C</li>
	<li>UART</li>
</ul>

<h3>Additional Notes and Information</h3>

<p>Depending on the development board you are using, you may need USB UART Click Board™, USB UART 2 Click Board™ or RS232 Click Board™ to connect to your PC, for development systems with no UART to USB interface available on the board. The terminal available in all MikroElektronika compilers, or any other terminal application of your choice, can be used to read the message.</p>

<h3>MIKROSDK</h3>

<p>The <strong>Force 4 Click Board™</strong> is supported with mikroSDK - MikroElektronika Software Development Kit. To ensure proper operation of mikroSDK compliant Click board™ demo applications, mikroSDK should be downloaded from the LibStock and installed for the compiler you are using.</p>

- summary: <p>The<em><strong> Force 4 Click Board™</strong></em><span> is based on HSFPAR003A piezoresistive force sensor from Alpsalpine. This product is a force sensor using the effect of a piezoresistive bridge circuit formed on a silicon diaphragm. Piezoresistive force sensors achieve higher linearity than other force sensors.</span></p>
<p>To help with stability and accuracy <strong>Force 4 Click Board™</strong> also includes MCP1101-33 a high precision buffered voltage reference as a power supply to a force sensor that allows high stability and accuracy of output voltage readings.</p>
