Library Description

Library provides function for reading ADC data from device and converting that data to power draw of connected device.

Key functions:

• uint16_t isoadc_read_adc ( void ) - Function for reading ADC data
• void isoadc_get_rshunt ( uint16_t adc_data, isoadc_rshunt_t *rshunt_param ) - Function for converting ADC to power supply and current on rshunt
• float isoadc_get_power ( isoadc_rshunt_t *rshunt_param ) - Function for reading power draw

Examples description

The application is composed of three sections :

• System Initialization - Initialization of SPI module
• Application Initialization - Timer interrupt initialization, and sets vext
• Application Task - Reads ADC data from device and avarages it

void application_task ( )
{
    adc_data = isoadc_read_adc();
    avg_data += adc_data;
    avg_cnt++;
}

Additional Functions :

• void InitTimer2() - Function for interrupt initialization
• void Timer2_interrupt ( ) iv IVT_INT_TIM2 - Funcion when interrupt occurred writes converted values

Other mikroE Libraries used in the example:

• SPI
• Conversions
• UART

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.
