Library Description
Library provides functions for using SPI module, changing pin states. Also it gives you function for controlling memory of device.
Key functions:
void semperflash2_send_cmd ( uint8_t cmd )
- Function for sending one byte of datavoid semperflash2_transfer_data ( uint8_t *write_buf, uint8_t *read_buf, uint16_t buf_size )
- Function for transfering data via SPI modulevoid semperflash2_write_data ( uint8_t *data_buf, uint16_t buf_size )
- Function for writing data via SPI modulevoid semperflash2_write_config ( seperflash2_cfg_t *cfg_data )
- Function for writing new config to deviceuint8_t semperflash2_read_memory ( uint32_t addr, uint8_t *data_buf, uint16_t buf_size )
- Function for reading memory from specific addressuint8_t semperflash2_write_memory ( uint32_t addr, uint8_t *data_buf, uint16_t buf_size )
- Function for writing memory to specific addressExamples description
The application is composed of three sections :
void application_task ( )
{
memset( &read_buf_data[ 0 ], 0, 13 );
semperflash2_send_cmd( SEMPERFLASH2_WRITE_ENABLE );
semperflash2_erase_memory( ADRESS_MEMORY );
Delay_ms( 1000 );
if ( COMPANY_FLAG == txt_flag )
{
semperflash2_send_cmd( SEMPERFLASH2_WRITE_ENABLE );
status_data = semperflash2_write_memory( ADRESS_MEMORY, &write_data_com[ 0 ], 7 );
error_handler( status_data );
status_data = semperflash2_read_memory( ADRESS_MEMORY, &read_buf_data[ 0 ], 7 );
error_handler( status_data );
mikrobus_logWrite( read_buf_data, _LOG_LINE );
txt_flag = CLICK_FLAG;
}
else if ( CLICK_FLAG == txt_flag )
{
semperflash2_send_cmd( SEMPERFLASH2_WRITE_ENABLE );
status_data = semperflash2_write_memory( ADRESS_MEMORY, &write_data_clk[ 0 ], 13 );
error_handler( status_data );
status_data = semperflash2_read_memory( ADRESS_MEMORY, &read_buf_data[ 0 ], 13 );
error_handler( status_data );
mikrobus_logWrite( read_buf_data, _LOG_LINE );
txt_flag = COMPANY_FLAG;
}
mikrobus_logWrite( "....................", _LOG_LINE );
Delay_ms( 2000 );
}

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.
