Click library

  • Author : Stefan Ilic
  • Date : Aug 2021.
  • Type : ADC type

Software Support

We provide a library for the EMG 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 from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.

Library Description

This library contains API for EMG Click driver.

Standard key functions :

Example key functions :

Example Description

This is an example which demonstrates the use of EMG Click board.

The demo application is composed of two sections :

Application Init

Initializes ADC and timer counter.

void application_init ( void ) {
log_cfg_t log_cfg;
emg_cfg_t emg_cfg;
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, " Application Init " );
// Click initialization.
emg_cfg_setup( &emg_cfg );
EMG_MAP_MIKROBUS( emg_cfg, MIKROBUS_1 );
if ( ADC_ERROR == emg_init( &emg, &emg_cfg ) ) {
log_error( &logger, " Application Init Error. " );
log_info( &logger, " Please, run program again... " );
for ( ; ; );
}
time = 0;
log_info( &logger, " Application Task " );
}

Application Task

Reads ADC value and sends results on serial plotter every 5 ms.

void application_task ( void ) {
uint16_t emg_an = 0;
if ( emg_read_an_pin_value( &emg, &emg_an ) == ADC_SUCCESS ){
log_printf( &logger, " %u,%lu\r\n ", emg_an, time );
}
time += 5;
Delay_ms( 5 );
}

The full application code, and ready to use projects can be installed directly from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.

Other Mikroe Libraries used in the example:

  • MikroSDK.Board
  • MikroSDK.Log
  • Click.EMG

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. UART terminal is available in all MikroElektronika compilers.
