• CIC Prefix : FRAM
• Author : MikroE Team
• Verison : 1.0.0
• Date : jan 2018.

We provide a library for the FRAM Click on our LibStock page, as well as a demo application (example), developed using MikroElektronika compilers. The demo can run on all the main MikroElektronika development boards.

Library Description

Key functions :

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

Examples Description

• System Initialization - GPIO and SPI module Initalization
• Application Initialization -Fram Driver Initialization, initialization of click by setting mikorBUS pins to approprieate 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);
}

The full application code, and ready to use projects can be found on our LibStock page.

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.
