Library Description

Librari provides functions for reading and writing to registers. You have functions for setting parameters, sending commands and configurating device channels. There is function for reading all channels if they are enabled.

Key functions:

• uint8_t proximity13_generic_read ( uint8_t reg_adr ) - Generic read function from registers
• void proximity13_generic_write ( uint8_t reg_adr, uint8_t write_data ) - Generic write function to registers
• uint8_t proximity13_get_int_pin_status ( void ) - Function for reading status of int pin
• uint8_t proximity13_send_command ( uint8_t cmd_val ) - Function for sending commands
• uint8_t proximity13_set_parameter ( uint8_t param, uint8_t cmd_val ) - Function for setting parameters
• uint8_t porximity13_config_channel ( uint8_t chn_num, proximity13_cfg_t cfg_val ) - Function for configurating specific channel
• void proximity13_read_channels ( proximity13_chn_val_t *chn_val ) - Fucnction for reading from all enabled channels

Examples description

The application is composed of three sections :

• System Initialization - Initialization of I2C module and setting int pin to output
• Application Initialization - Check id status, configures device and sends command for measurement
• Application Task - Appliction measures values very 100ms and converts it to 24bit

void application_task ( )
{
    proximity13_chn_val_t chn_val;
    char txt[ 30 ];

    proximity13_read_channels( &chn_val );

    WordToStr( chn_val.channel_1, txt );
    mikrobus_logWrite( "Data :", _LOG_TEXT );
    mikrobus_logWrite( txt, _LOG_LINE );

    Delay_ms ( 100 );
}

Other mikroE Libraries used in the example:

• I2C
• UART
• Conversions

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.
