Library Description
The library covers all the necessary functions to control SPI Isolator 2 Click board™. Library performs a standard SPI interface communication.
Key functions:
void spiisolator2_output_enable ( uint8_t en_out )
- Output enable function.int8_t addr_n_bytes, uint8_t *p_tx_data, uint8_t tx_data_n_bytes )
- Multi write function.uint8_t addr_n_bytes, uint8_t *p_rx_data, uint8_t tx_data_n_bytes )
- Multi read function.Examples description
The application is composed of three sections :
void application_task ( )
{
spiisolator2_set_cmd( SPIISOLATOR2_EEPROM5_CMD_WRITE_ENABLE );
Delay_ms( 10 );
spiisolator2_multi_write( SPIISOLATOR2_EEPROM5_CMD_WRITE | memory_address,
4,
&demo_data[ 0 ],
9 );
mikrobus_logWrite( " Write data : ", _LOG_TEXT );
for ( n_cnt = 0; n_cnt < 9; n_cnt++ )
{
mikrobus_logWrite( &demo_data[ n_cnt ], _LOG_BYTE );
}
mikrobus_logWrite( "- - - - - - - - - - - ", _LOG_LINE );
Delay_ms( 100 );
mikrobus_logWrite( " Read data : ", _LOG_TEXT );
spiisolator2_multi_read( SPIISOLATOR2_EEPROM5_CMD_READ | memory_address,
4,
&read_data[ 0 ],
9 );
Delay_ms( 1000 );
for ( n_cnt = 0; n_cnt < 9; n_cnt++ )
{
mikrobus_logWrite( &read_data[ n_cnt ], _LOG_BYTE );
}
mikrobus_logWrite( "----------------------", _LOG_LINE );
Delay_ms( 5000 );
}

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.
