One Shot Click is equipped with the monostable multivibrator (also known as a “one-shot” pulse generator) with a programmable pulse width of 1μs to 33.6 seconds. The used LTC6993-2 is part of the TimerBlox® family of versatile silicon timing devices, from Analog Devices.
We provide a library for the OneShot Click as well as a demo application (example), developed using MikroElektronika compilers. The demo can run on all the main MikroElektronika development boards.
Package can be downloaded/installed directly form compilers IDE(recommended way), or downloaded from our LibStock, or found on mikroE github account.
This library contains API for OneShot Click driver.
Config Object Initialization function.
void oneshot_cfg_setup ( oneshot_cfg_t *cfg );
Initialization function.
ONESHOT_RETVAL oneshot_init ( oneshot_t ctx, oneshot_cfg_t cfg );
Click Default Configuration function.
void oneshot_default_cfg ( oneshot_t *ctx );
This function reads the resistance data from the AD5241 chip.
float oneshot_get_resistance ( oneshot_t *ctx );
This function reads the digital signal from the RST pin.
uint8_t oneshot_digital_read_rst ( oneshot_t *ctx );
This function writes the specified digital signal to the CS pin.
void oneshot_digital_write_cs ( oneshot_t *ctx, uint8_t signal );
This example shows the user how to configure and use the One Shot Click. The Click has a monostable monovibrator which cam generate a pulse of width between 1μs and 33.6 seconds.
The demo application is composed of two sections :
This function initializes and configures the logger and Click modules. Resistance data, acquired from the AD5241, is displayed at the end of the initialization process.
void application_init ( )
{
log_cfg_t log_cfg;
oneshot_cfg_t cfg;
/**
* Logger initialization.
* Default baud rate: 115200
* Default log level: LOG_LEVEL_DEBUG
* @note If USB_UART_RX and USB_UART_TX
* are defined as HAL_PIN_NC, you will
* need to define them manually for log to work.
* See @b LOG_MAP_USB_UART macro definition for detailed explanation.
*/
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, "---- Application Init ----" );
// Click initialization.
oneshot_cfg_setup( &cfg );
ONESHOT_MAP_MIKROBUS( cfg, MIKROBUS_1 );
oneshot_init( &oneshot, &cfg );

oneshot_default_cfg( &oneshot );
Delay_100ms( );
log_printf( &logger, " * Resistance: %.1f Ohm\r\n", oneshot_get_resistance( &oneshot ) );
}
This function triggers one shot every 8 seconds.
void application_task ( )
{
oneshot_digital_write_cs( &oneshot, 1 );
Delay_ms ( 1 );
oneshot_digital_write_cs( &oneshot, 0 );

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.
