Library Description

The library covers all the necessary functions to control One Shot click. User can use functions to set or check state of AD5241, set or clear trigger pin and check output pin.

Key functions:

• void oneshot_setTrig( uint8_t state ) - Changes the state of trigger pin.
• uint8_t oneshot_checkOut() - Checks the state of output pin.
• float oneshot_getR() - Calculates resistance of AD5241.

Examples description

The application is composed of three sections :

• System Initialization - Initializes I2C and LOG structures, sets CS pin as output and RST pin as input.
• Application Initialization - Initialization driver enables I2C and also starts write log.
• Application Task - (code snippet) This example demonstrates the use of One Shot click. When value 0x18 is applied on AD5241, trigger pin is cleared and ressistance between TP1 i TP2 is set to 27 kohm, One Shot click produces one 0.5s pulse.

void applicationTask()
{
    oneshot_setTrig( 0 );
}

Other mikroE Libraries used in the example:

• I2C
• UART
• Conversions

Additional notes and informations

Depending on the development board you are using, you may need 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.
