Smoke Click

Smoke Click demo application is developed using the NECTO Studio, ensuring compatibility with mikroSDK's open-source libraries and tools. Designed for plug-and-play implementation and testing, the demo is fully compatible with all development, starter, and mikromedia boards featuring a mikroBUS™ socket.


Click Library

  • Author : MikroE Team
  • Date : Feb 2020.
  • Type : I2C type

Software Support

Example Description

This Click includes internal LEDs, photodetectors, optical elements, and low-noise electronics with ambient light rejection. The sensor can detect a wide variety of smoke particle sizes. It also has an on-chip temperature sensor for calibrating the temperature dependence of the particle sensing subsystem. The temperature sensor has an inherent resolution 0.0625°C.

Example Libraries

  • MikroSDK.Board
  • MikroSDK.Log
  • Click.Smoke

Example Key Functions

Application Init

Initalizes I2C driver, and sets default configuration of device.

void application_init ( void )
{
log_cfg_t log_cfg;
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, "---- Application Init ----" );
// Click initialization.
smoke_cfg_setup( &cfg );
SMOKE_MAP_MIKROBUS( cfg, MIKROBUS_1 );
smoke_init( &smoke, &cfg );
smoke_reset( &smoke );
smoke_default_cfg ( &smoke );
log_info( &logger, "---- Application Task ----" );
Delay_ms ( 100 );
if ( smoke_read_leds( &smoke ) != SMOKE_OK )
{
log_info( &logger, "---- Init Error ----" );
for( ; ; );
}
}
#define SMOKE_OK
Definition smoke.h:78
#define SMOKE_MAP_MIKROBUS(cfg, mikrobus)
Definition smoke.h:66
void smoke_reset(smoke_t *ctx)
Reset device function.
void application_init(void)
Definition main.c:42

Application Task

This example demonstrates the use of Smoke Click board. It reads reflected red, ir, green and temperature values from an internal sensor and displays and logs it.

void application_task ( void )
{
smoke_read_leds( &smoke );
log_printf( &logger, "Red : %llu\r\n", smoke.red_value );
log_printf( &logger, "IR : %llu\r\n", smoke.ir_value );
log_printf( &logger, "Green : %llu\r\n", smoke.green_value );
log_printf( &logger, "------------------------------\r\n" );
temperature = smoke_read_temp( &smoke );
log_printf( &logger, "Read Temperature[ degC ]: %.2f\r\n", temperature );
log_printf( &logger, "------------------------------\r\n" );
Delay_ms ( 500 );
}
float smoke_read_temp(smoke_t *ctx)
Read temperature in Centigrade function.
void application_task(void)

Application Output

This Click board can be interfaced and monitored in two ways:

  • Application Output - Use the "Application Output" window in Debug mode for real-time data monitoring. Set it up properly by following this tutorial.
  • UART Terminal - Monitor data via the UART Terminal using a USB to UART converter. For detailed instructions, check out this tutorial.

Additional Notes and Information

The complete application code and a ready-to-use project are available through the NECTO Studio Package Manager for direct installation in the NECTO Studio. The application code can also be found on the MIKROE GitHub account.
