4-20mA T Click is an add-on board in mikroBUS form factor. It’s a compact and easy solution for adding 4-to-20mA industry standard communication protocol to your design
We provide a library for the C420mat 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 C420mat Click driver.
Config Object Initialization function.
void c420mat_cfg_setup ( c420mat_cfg_t *cfg );
Initialization function.
C420MAT_RETVAL c420mat_init ( c420mat_t ctx, c420mat_cfg_t cfg );
This function sets the output of DAC.
void c420mat_dac_output ( c420mat_t *ctx, uint16_t value_dac );
This function sets the output current to selected value.
void c420mat_set_i_out ( c420mat_t *ctx, uint8_t i_out );
This aplication changes the value of the output current.
The demo application is composed of two sections :
Initializes Click SPI driver.
void application_init ( void )
{
log_cfg_t log_cfg;
c420mat_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.
c420mat_cfg_setup( &cfg );
C420MAT_MAP_MIKROBUS( cfg, MIKROBUS_1 );
c420mat_init( &c420mat, &cfg );
}
Periodically changes Iout value.
void application_task ( void )
{
c420mat_set_i_out( &c420mat, 56 ); // sets Iout to 5.6mA
Delay_ms ( 1000 );
Delay_ms ( 1000 );
Delay_ms ( 1000 );
c420mat_set_i_out( &c420mat, 158 ); // sets Iout to 15.8mA
Delay_ms ( 1000 );
Delay_ms ( 1000 );
Delay_ms ( 1000 );
}
The full application code, and ready to use projects can be installed directly form compilers IDE(recommneded) or found on LibStock page or mikroE GitHub accaunt.

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.
