Library Description

The library contains functions to provide communication between 2 or more click boards.

Key functions:

  • void ft_send_package( uint8_t *data_buf, uint16_t len, uint8_t queue ) - Sends full package to other module
  • void ft_process ( uint8_t rsp_data ) - Collecting and preserving data received via uart interrupt routine
  • uint16_t ft_get_data ( uint8_t *data_buf ) - Gets new received data

Examples description

The application is composed of three sections :

  • System Initialization - Initialize UART module and sets aplication mode (RX or TX)
  • Application Initialization - Initialize driver init
  • Application Task - RX mode : Reads and logs new receive data. TX mode : sends (MikroE) data every 1 seconds.
void application_task ( )
{
    if ( app_mode == APP_MODE_RX )
    {
        if ( ft_get_data_status( ) == FT_NEW_DATA_AVAILABLE )
        {
            rsp_data_num = ft_get_data( &rsp_data_buf[ 0 ] );
            if( rsp_data_num != 0 )
            {
                mikrobus_logWrite( "---------------------------", _LOG_LINE );
                mikrobus_logWrite( "--> READ: ", _LOG_TEXT );
                mikrobus_logWrite( rsp_data_buf, _LOG_LINE );
                mikrobus_logWrite( "---------------------------", _LOG_LINE );
            }
        }
    }
    else
    {
        mikrobus_logWrite( "--------------------------", _LOG_LINE );
        mikrobus_logWrite( "-->  SEND MIKROE DATA  <--", _LOG_LINE );
        mikrobus_logWrite( "--------------------------", _LOG_LINE );
        ft_send_package( &MIKROE_DATA_BUF[ 0 ], MIKROE_DATA_BUF_LEN, MIKROE_DATA_QUEUE );
        Delay_ms( 1000 );
    }
}

Note - Before the start program check uart interrupt routine in the Click_FT_other peripherals file.

  • UART Library
  • Conversions library

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.

MRAM 4 Click

0

MRAM 4 Click is a compact add-on board representing a magneto-resistive random-access memory solution. This board features the EM064LX, an industrial STT-MRAM persistent memory from Everspin Technologies. It is a 64Mb MRAM IC RAM and can achieve up to 200MHz as a single and double data rate (STR/DTR). The MRAM technology is analog to Flash technology with SRAM-compatible read/write timings (Persistent SRAM, P-SRAM), where data is always non-volatile. It also has a hardware write-protection feature and performs read and write operations with data retention for ten years and unlimited read, write, and erase operations for the supported life of the chip.

AC Current Click

0

AC Current Click is a device that is able to measure the alternating current (AC) running through the conductor, using the so-called non-invasive current sensor. The non-invasive sensor works by utilizing the electromagnetic induction phenomenon, similar to a transformer. The primary coil does not exist though, the electromagnetic field is generated by the AC Current running through the cable which is measured. The core of the sensing probe is split, allowing it to clamp on the current conducting cable. Since the sensor does not influence the measurement circuitry in any way while being galvanically isolated at the same time, it is an ideal solution to measure current running through mains, or similar high voltage installations.
