Voltmeter click is a mikroBUS™ add-on board for measuring voltage in an external electric circuit. The board is designed to measure Direct Current only, and has a measurement range from 0 to 24V (it’s possible to measure both positive and negative charges).
We provide a library for the Voltmeter 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 form compilers IDE(recommended way), or downloaded from our LibStock, or found on mikroE github account.
This library contains API for Voltmeter Click driver.
void voltmeter_cfg_setup ( voltmeter_cfg_t *cfg );
VOLTMETER_RETVAL voltmeter_init ( voltmeter_t *ctx, voltmeter_cfg_t *cfg );
void voltmeter_write_data ( voltmeter_t *ctx, uint16_t write_data );
uint8_t voltmeter_read_byte ( voltmeter_t *ctx );
uint16_t voltmeter_read_data ( voltmeter_t *ctx );
This application give a voltage in milivolts
The demo application is composed of two sections :
Initialization driver enables - I2C,
start calibration reading and also write log.
This is an example which demonstrates the use of Voltmeter Click board.
These examples read ADC value from the register of MCP3201 chip on the Voltmeter click board and calculate the voltage value [ mV ]. Results are being sent to the Usart Terminal where you can track their changes.
The full application code, and ready to use projects can be installed directly form compilers IDE(recommneded) or found on LibStock page or mikroE GitHub accaunt.

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.
