ISO ADC 3 click

ISO ADC 3 Click is a compact add-on board that contains a single-channel precision isolation amplifier. This board features the AMC1100, a precision isolation amplifier with an output separated from the input circuitry by a silicon dioxide barrier that is highly resistant to magnetic interference from Texas Instruments.

Software Support

We provide a library for the ISOADC3 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 ISOADC3 Click driver.

Standard key functions :

Example key functions :

Example Description

This example shows the capabilities of the ISO ADC 3 click.

The demo application is composed of two sections :

Application Init

Initalizes I2C driver and makes an initial log.

void application_init ( void ) {
log_cfg_t log_cfg;
isoadc3_cfg_t isoadc3_cfg;
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, " Application Init " );
// Click initialization.
isoadc3_cfg_setup( &isoadc3_cfg );
ISOADC3_MAP_MIKROBUS( isoadc3_cfg, MIKROBUS_1 );
err_t init_flag = isoadc3_init( &isoadc3, &isoadc3_cfg );
if ( I2C_MASTER_ERROR == init_flag ) {
log_error( &logger, " Application Init Error. " );
log_info( &logger, " Please, run program again... " );
for ( ; ; );
}
log_info( &logger, " Application Task " );
}

Application Task

Measures ADC voltage level and prints it via USB UART terminal.

void application_task ( void ) {
log_printf( &logger, " ADC voltage Level: %d mV \r\n", voltage );
log_printf( &logger, "------------------------\r\n" );
Delay_ms( 1000 );
}

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.ISOADC3

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.
