Das Force 5 Click Board™ ist eine kompakte Zusatzplatine, die einen stabilen und flexiblen kompensierten/verstärkten Mikrokraftsensor enthält. Diese Platine verfügt über den FMAMSDXX025WC2C3, einen piezoresistiven Kraftsensor mit einem digitalen Ausgang zum Ablesen der Kraft über den angegebenen vollen Kraftbereich und einen Temperaturbereich von Honeywell Sensing and Productivity Solutions. Der sehr stabile digitale Ausgang, der direkt proportional zur auf die mechanisch gekoppelte Kugel ausgeübten Kraft ist, die verbesserte Genauigkeit und das reduzierte Gesamtfehlerband, das die Systemleistung verbessert, sind nur einige der guten Eigenschaften dieses Sensors. Dieses Click Board™ ist für industrielle Anwendungen wie Kraft-/Griffmessgeräte, Last- und Kompressionssensoren, Robotik und mehr geeignet.
Force 5 Click wird von einer mikroSDK-kompatiblen Bibliothek unterstützt, die Funktionen enthält, die die Softwareentwicklung vereinfachen. Dieses Click Board™ wird als vollständig getestetes Produkt geliefert und ist bereit für den Einsatz auf einem System, das mit der mikroBUS™-Buchse ausgestattet ist.
How Does The Force 5 Click Board™ Work?
The Force 5 Click Board™ is based on the FMAMSDXX025WC2C3, a piezoresistive-based force sensor offering a digital output for reading force over the specified full-scale force span and a temperature range from Honeywell Sensing and Productivity Solutions. This sensor belongs to the group the FMA Series designed to meet the user's need for a compensated, amplified force sensor that provides digital outputs, a variety of force sensing ranges, a small, cost-effective format, and enhanced durability and accuracy.
The flexible design of the FMAMSDXX025WC2C3 operates over a wide operating temperature range. It has a force range of 25 newtons that maximizes sensitivity and improve system resolution/performance, enhanced accuracy which includes all errors due to force non-linearity and non-repeatability, and diagnostic functions which allow the user to determine if the sensor is working correctly by detecting if electrical paths are broken or shorted inside the sensor. This Click board™ offers a very stable digital output that is directly proportional to the force applied to the mechanically-coupled sphere that enhances performance through reduced conversion requirements and the convenience of a direct interface to MCU.
The Force 5 Click Board™ communicates with MCU using the standard I2C 2-Wire interface with a maximum frequency of 400kHz. This Click board™ is easy to program because it does not require an overly demanding configuration. The code example that MikroE provides to its users consists of calibrating the sensor and displaying the diagnostic status (whether the sensor is in Normal operation, Command mode, or Stale mode). After successful calibration, the force and temperature are measured, after which the digital output data are displayed every 500 ms.
This Click board™ is designed to be operated only with a 3.3V logic voltage level. A proper logic voltage level conversion should be performed before the Click board™ is used with MCUs with different logic levels. However, the Click board™ comes equipped with a library that contains easy to use functions and an example code that can be used as a reference for further development.

Software Support
We provide a library for the Force 5 Click Board™ 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.
Library Description
The library covers all the necessary functions to control the Force 5 Click Board™. The library performs a standard I2C interface communication.
Key Functions
void force5_read_all_data ( force5_data_t *force_data )- Read all data function.float force5_get_force ( force5_calibration_t calib_data )- Get force function.float force5_get_temperature ( void )- Get temperature function.
Example Description
The application is composed of three sections :
- The application is composed of three sections :
- Application Initialization - Initialization driver enables - I2C, calibration the device, display diagnostic states and temperature.
- Application Task - (code snippet) This is an example that demonstrates the use of the Force 5 Click Board™. Force 5 Click board can be used to measure digital output force ( N ). All data logs write on USB uart changes every 500 milliseconds.
void application_task ( )
{
force_n = force5_get_force( calib_data );
FloatToStr( force_n, log_text );
mikrobus_logWrite( " Force : ", _LOG_TEXT );
mikrobus_logWrite( log_text, _LOG_TEXT );
mikrobus_logWrite( " N", _LOG_LINE );
mikrobus_logWrite( "-------------------------", _LOG_LINE );

Additional Notes and Information
Depending on the development board you are using, you may need a USB UART click, USB UART 2 click or RS232 click 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.
mikroSDK
The Force 5 Click Board™ 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.
