# FRAM Click | ||
|
||
--- | ||
|
||
- **CIC Prefix** : FRAM | ||
- **Author** : MikroE Team | ||
- **Verison** : 1.0.0 | ||
- **Date** : jan 2018. | ||
|
||
--- | ||
|
||
### Software Support | ||
|
||
We provide a library for the FRAM Click on our [LibStock](http://libstock.mikroe.com/projects/view/776/fram-click-example) | ||
page, as well as a demo application (example), developed using MikroElektronika | ||
[compilers](http://shop.mikroe.com/compilers). The demo can run on all the main | ||
MikroElektronika [development boards](http://shop.mikroe.com/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. | ||
|
||
|
||
|
||
```.c | ||
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](http://libstock.mikroe.com/projects/view/776/fram-click-example) 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](http://shop.mikroe.com/usb-uart-click), | ||
[USB UART 2 Click](http://shop.mikroe.com/usb-uart-2-click) or | ||
[RS232 Click](http://shop.mikroe.com/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](http://shop.mikroe.com/compilers), or any other terminal application | ||
of your choice, can be used to read the message. | ||
