PAC1934 click carries the PAC1934 four channel DC power/energy monitor from Microchip. The click is designed to run on either 3.3V or 5V power supply. It communicates with the target microcontroller over an I2C interface.
We provide a library for the Pac1934 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 Pac1934 Click driver.
void pac1934_cfg_setup ( pac1934_cfg_t *cfg );
PAC1934_RETVAL pac1934_init ( pac1934_t *ctx, pac1934_cfg_t *cfg );
void pac1934_write_byte ( pac1934_t *ctx, uint8_t wr_addr, uint8_t wr_data );
uint8_t pac1934_read_byte ( pac1934_t *ctx, uint8_t rd_addr );
void pac1934_send_command ( pac1934_t *ctx, uint8_t wr_cmd );
This application measures the voltage.
The demo application is composed of two sections :
Initalizes device, enables the device and makes an initial log.
This is an example that shows the most important functions that PAC1934 click has, it mesures voltage, current, power and energy.
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.
