- Type : UART type
Software Support
We provide a library for the EZO Carrier DO 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.

Standard key functions :
ezocarrierdo_cfg_setup
Config Object Initialization function.
void ezocarrierdo_cfg_setup(ezocarrierdo_cfg_t *cfg)
EZO Carrier DO configuration object setup function.
EZO Carrier DO Click configuration object.
Definition: ezocarrierdo.h:171
ezocarrierdo_init
Initialization function.
err_t ezocarrierdo_init(ezocarrierdo_t *ctx, ezocarrierdo_cfg_t *cfg)
EZO Carrier DO initialization function.
EZO Carrier DO Click context object.
Definition: ezocarrierdo.h:151
Example key functions :
ezocarrierdo_send_cmd
Send command function.
void ezocarrierdo_send_cmd(ezocarrierdo_t *ctx, uint8_t *cmd)
Send command function.
ezocarrierdo_send_cmd_with_par
Send command function with parameter.
void ezocarrierdo_send_cmd_with_par(ezocarrierdo_t *ctx, uint8_t *cmd, uint8_t *param_buf)
Send command function with parameter.
ezocarrierdo_send_cmd_check

void ezocarrierdo_send_cmd_check(ezocarrierdo_t *ctx, uint8_t *cmd)
Check the sent command.
Example Description
This example demonstrates the use of EZO Carrier DO click board by processing
the incoming data and displaying them on the USB UART.
The demo application is composed of two sections :
Application Init
Initializes the driver, performs the click default factory reset, and high point calibration.
{
log_cfg_t log_cfg;
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, " Application Init " );
{
log_error( &logger, " Communication init." );
for ( ; ; );
}
log_printf( &logger, "Device status \r\n" );
ezocarrierdo_error_check( error_flag );
log_printf( &logger, "Factory reset \r\n" );
ezocarrierdo_error_check( error_flag );
log_printf( &logger, "Device info \r\n" );
ezocarrierdo_error_check( error_flag );
uint8_t n_cnt = 0;
ezocarrierdo_clear_app_buf( );
ezocarrierdo_process ( &ezocarrierdo );
strcpy( last_reading, app_buf );
log_printf( &logger, "High point calibration \r\n" );
log_printf( &logger, "Waiting for stable readings \r\n" );
while ( n_cnt <= 5 )
{
{
if ( 0 == strstr( app_buf, last_reading ) )
{
n_cnt++;
}
else
{
strcpy( last_reading, app_buf );
n_cnt = 0;
}
}
log_printf( &logger, "- " );
Delay_ms( 1000 );
ezocarrierdo_clear_app_buf( );
}
log_printf( &logger, "\r\n Calibration \r\n" );
ezocarrierdo_error_check( error_flag );
#define DISABLE_CONT_READ "0"
log_printf( &logger, "Disable continuous reading mode \r\n" );
ezocarrierdo_error_check( error_flag );
log_info( &logger, " Application Task " );
}

Application Task
Reads and processes all incoming dissolved oxygen data from the probe, and displays them on the USB UART in mg/L.
{
log_printf( &logger, "Reading... \r\n" );
ezocarrierdo_error_check( error_flag );
Delay_ms( 5000 );

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.
