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.
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.
This library contains API for ISOADC3 Click driver.
isoadc3_cfg_setup
Config Object Initialization function.
void isoadc3_cfg_setup ( isoadc3_cfg_t *cfg );
isoadc3_init
Initialization function.
err_t isoadc3_init ( isoadc3_t *ctx, isoadc3_cfg_t *cfg );
isoadc3_read_adc
Read ADC function.
uint16_t isoadc3_read_adc ( isoadc3_t *ctx );
isoadc3_get_adc_voltage
Read ADC voltage function.
uint16_t isoadc3_get_adc_voltage ( isoadc3_t *ctx, uint16_t v_ref );
isoadc3_read_voltage
Read voltage function.
uint16_t isoadc3_read_voltage ( isoadc3_t *ctx, uint16_t v_ref );
This example shows the capabilities of the ISO ADC 3 Click.
The demo application is composed of two sections :
Initalizes I2C driver and makes an initial log.
void application_init ( void ) {
log_cfg_t log_cfg; /**< Logger config object. */
isoadc3_cfg_t isoadc3_cfg; /**< Click config object. */
/**
* 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.
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 " );
}
Measures ADC voltage level and prints it via USB UART terminal.
void application_task ( void ) {
voltage = isoadc3_read_voltage( &isoadc3, ISOADC3_VREF_3V3 );
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.

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.
