Key functions:

• void flash2_read( uint32_t address, uint8_t *buffer,uint32_t data_count ); - The function reads data from selected address.
• void flash2_write( uint32_t address, uint8_t *buffer,  uint32_t data_count ); - The function writes data to  selected address.
• void flash2_chipErase( void ); - The chip erase function clears all bits in the device 1.

Examples Description

The application is composed of three sections:

• System Initialization - GPIO and SPI module Initialization.
• Application Initialization - Flash Driver Initialization, initialization of click by setting mikorBUS to appropriate logic levels, performing global block unlock and chip erase functions.
• Application Task - Writing data to click memory and displaying the read data via UART.

void applicationTask()
{

 mikrobus_logWrite("Writing MikroE to Flash memory, from address 0x015015:",
_LOG_LINE);
 flash2_write (0x015015, &wrData[0], 9);
 mikrobus_logWrite("Reading 9 bytes of Flash memory, from address 0x015015:",
_LOG_LINE);
 flash2_read(0x015015,&rdData[0],9);
 mikrobus_logWrite("Data read: ",_LOG_TEXT);
 mikrobus_logWrite(rdData,_LOG_LINE);
 Delay_ms(1000);
}

Other mikroE Libraries used in the example:

• SPI
• UART

Additional notes and information

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.
