Library Description

The library contains basic communication with the module and allows the user to read and write data to the module. The user can read the current data of current, voltage and power measured by the sensor.

Key functions:

• float vcpmonitor2_get_shunt_voltage ( uint8_t channel ) - Get Shunt voltage in mV
• float vcpmonitor2_get_current ( uint8_t channel ) - Get Current data in mA
• float vcpmonitor2_get_power ( uint8_t channel ) - Get Power in W

Examples description

The application is composed of three sections :

• System Initialization - Initialization I2C module and RST pin on OUTPUT
• Application Initialization - Initiaization driver init, device configuration for measurement, alert status reset and configuration
• Application Task - Display Voltage on the BUS and Shunt, current and power data. Display Alert status informations.

void application_task ( )
{
    mikrobus_logWrite( ">> CHANNEL 1 <<", _LOG_LINE );
    display_channel_data( VCPMONITOR2_CHANNEL_1 );
    mikrobus_logWrite( ">> CHANNEL 2 <<", _LOG_LINE );
    display_channel_data( VCPMONITOR2_CHANNEL_2 );
    mikrobus_logWrite( ">> CHANNEL 3 <<", _LOG_LINE );
    display_channel_data( VCPMONITOR2_CHANNEL_3 );
    display_alert_status( );
    mikrobus_logWrite( "---------------------", _LOG_LINE );
    Delay_ms( 4000 );
}

Additional Functions :

• display_alert_status() - Alert status
• display_channel_data() - Channel data

Other mikroE Libraries used in the example:

• I2C Library
• UART Library

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.
