Library Description

Library provides control over reading and writing data via I2C module. You can use 2 specific functions for reading and writing to memory.

Key functions:

  • void fram3_read_data ( uint8_t *data_buf, uint8_t n_buf_size ) - Generic read data function
  • void fram3_write_data ( uint8_t *data_buf, uint8_t n_buf_size ) - Generic write data function
  • uint8_t fram3_read_free_access_memory ( uint8_t start_addr, uint8_t *data_buf, uint8_t n_buf_size ) - Memory read function
  • uint8_t fram3_write_free_access_memory ( uint8_t start_addr, uint8_t *data_buf, uint8_t n_buf_size ) - Memory write function

Examples description

The application is composed of three sections :

  • System Initialization - Initializes I2C module
  • Application Initialization - Initializes driver init
  • Application Task - Writes and then reads data from memory
void application_task (  )
{
    mikrobus_logWrite( " - Writing... ", _LOG_LINE );
    Delay_ms( 500 );
    status_check = fram3_write_free_access_memory( 0x00, &write_data[ 0 ], 7 );
    if ( status_check == FRAM3_ERROR )
    {
        mikrobus_logWrite( " - ERROR WRITING!!! ", _LOG_LINE );
        for ( ; ; );
    }
    
    mikrobus_logWrite( " - Reading... ", _LOG_LINE );
    Delay_ms( 500 );
    status_check = fram3_read_free_access_memory( 0x00, &read_data[ 0 ], 7 );
    if ( status_check == FRAM3_ERROR )
    {
        mikrobus_logWrite( " - ERROR READING!!! ", _LOG_LINE );
        for ( ; ; );
    }

    for ( cnt = 0; cnt < 7; cnt++ )
    {
        mikrobus_logWrite( &read_data[ cnt ], _LOG_BYTE );
        Delay_ms( 100 );
    }
    mikrobus_logWrite( "", _LOG_LINE );
    Delay_ms( 1000 );
    mikrobus_logWrite( "__________________________", _LOG_LINE );
    Delay_ms( 500 );
}

  • I2C
  • UART

Additional notes and informations

Depending on the development board you are using, you may need USB UART clickUSB 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.

Angle 6 Click

0

Angle 6 Click is a compact add-on board that detects the absolute angular position of a permanent magnet, typically a diametrically magnetized cylinder on a rotating shaft. This board features the MAQ470GQE, a 12-bit contactless angle sensor with PWM output from Monolithic Power Systems. It supports a wide range of magnetic field strengths and spatial configurations, with both end-of-shaft and off-axis (side-shaft mounting), supported configurations. Fast data acquisition and processing provides accurate angle measurement at speeds from 0 to 60,000 rpm, alongside magnetic field strength detection with programmable thresholds.
