Library Description

Key functions:

• void eeram5v_read (uint16_t address, uint8_t * pDataOut, uint8_t countOut); - Reads the data from the selected SRAM address onwards.
• void eeram5v_write (uint16_t address, uint8_t * pDataIn, uint8_t countIn); - Writes the data to SRAM memory array.

Examples Description

The application is composed of three sections:

• System Initialization - I2C module initialization
• Application Initialization - EERAM5V driver initialization
• Application Task - Writing data to click memory and displaying the read data via UART.

void applicationTask()
{
 mikrobus_logWrite("Writing MikroE to SRAM memory, from address 0x0150:",
_LOG_LINE);
 eeram5v_write(0x0150, wrData, 9);

 mikrobus_logWrite("Reading 9 bytes of SRAM memory, from address 0x0150:",
_LOG_LINE);
 eeram5v_read(0x0150, rdData, 9);

 mikrobus_logWrite("Data read: ",_LOG_TEXT);
 mikrobus_logWrite(rdData,_LOG_LINE);
 Delay_ms(1000);
}

Other mikroE Libraries used in the example:

• I2C
• 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.
