DIGI Isolator 2 click

DIGI Isolator 2 Click is a compact add-on board that provides isolated digital input signals to your application. This board features the ISO1228, an eight-channel isolated digital input from Texas Instruments. It comes with 8-channel isolated 24V digital input receivers, with a current limit and diagnostics. The device also provides a field-side input-current-powered LED indication to reduce system power dissipation and reduce the board temperatures.

Software Support

We provide a library for the DIGI Isolator 2 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 DIGI Isolator 2 Click driver.

Example Description

This example demonstrates the use of DIGI Isolator 2 click board by reading and displaying the state of 8 digital input channels.

The demo application is composed of two sections :

Application Init

Initializes the driver and enables isolator outputs.

void application_init ( void )
{
log_cfg_t log_cfg;
digiisolator2_cfg_t digiisolator2_cfg;
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, " Application Init " );
// Click initialization.
digiisolator2_cfg_setup( &digiisolator2_cfg );
DIGIISOLATOR2_MAP_MIKROBUS( digiisolator2_cfg, MIKROBUS_1 );
if ( DIGIISOLATOR2_OK != digiisolator2_init( &digiisolator2, &digiisolator2_cfg ) )
{
log_error( &logger, " Communication init." );
for ( ; ; );
}
digiisolator2_enable_output( &digiisolator2 );
log_info( &logger, " Application Task " );
}

Application Task

Reads the state of 8 digital input channels in hex format where MSB represents IN8 and LSB the channel IN1. The results are displayed on the USB UART every 500ms.

void application_task ( void )
{
uint8_t input_data = 0;
if ( DIGIISOLATOR2_OK == digiisolator2_read_inputs ( &digiisolator2, &input_data ) )
{
log_printf( &logger, " INPUT: 0x%.2X\r\n\n", ( uint16_t ) input_data );
Delay_ms ( 500 );
}
}

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.DIGIIsolator2

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.
