Library Description

The library covers all the necessary functions to control Flash 7 Click board™. Library performs a standard SPI interface communication.

Key functions:

• void flash7_chip_erase ( void ) - Chip erase function.
• uint8_t flash7_page_program ( uint32_t mem_addr, uint8_t *p_tx_data, uint16_t n_bytes ) - Page program function.
• void flash7_read_memory ( uint32_t mem_addr, uint8_t *p_rx_data, uint16_t n_bytes ) - Read memory function.

Examples description

The application is composed of three sections :

• System Initialization - Initializes SPI and UART LOG, sets CS, PWM and INT pins as outputs.
• Application Initialization - Initialization driver enables SPI, disables write protect and hold, performs whole chip erase, targets the memory address at "4096" for page program starting point and writes data which is also displayed on the log.
• Application Task - This is an example that demonstrates the use of the Flash 7 Click board™. In this example, the data is read from the targeted memory address. The results are being sent to the Usart Terminal. This task repeats every 5 sec.

void application_task ( )
{
    mikrobus_logWrite( "-----------------------", _LOG_LINE );
    mikrobus_logWrite( "<- Read data  : ", _LOG_TEXT );
    flash7_read_memory( memory_addr, &rx_data[ 0 ], 9 );
    mikrobus_logWrite( rx_data, _LOG_LINE );
    Delay_ms( 5000 );
}

Other mikroE Libraries used in the example:

• SPI
• UART

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.
