Library Description

Key functions:

• void fram_write(uint16_t address, uint8_t *buffer, uint16_t counter) - The function writes to sequential memory locations from the buffer.
• void fram_read(uint16_t address, uint8_t *buffer, uint16_t count) - The function reads sequential memory locations to the buffer.
• void fram_writeEnable() - The function enables data writing in the FRAM memory space.

Examples Description

The application is composed of three sections:

• System Initialization - GPIO and SPI module Initialization.
• Application Initialization -  Fram Driver Initialization, initialization of click by setting mikorBUS pins to an appropriate logic level, performing erase all and write enable functions.
• Application Task - Writing data to click memory and displaying the read data via UART.

void applicationTask()
{
 mikrobus_logWrite("Writing MikroE to Fram memory, from address 0x0150:",
_LOG_LINE);
 fram_write (0x0150, &wrData[0], 9);
 mikrobus_logWrite("Reading 9 bytes of Fram memory, from address 0x0150:",
_LOG_LINE);
 fram_read(0x0150,&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.
