How to use this library

The I2C Memory library can be used as follows:

1. Add .h and source file in project.

2. Config Chipset in 'i2c_memory_conf.h' header, for example:

• Options:

  #define _AT24C04 // Chipset code
  
  #define _MEMORY_A0_PIN_STATE 0  // Address pin 0 state
  #define _MEMORY_A1_PIN_STATE 1  // Address pin 1 state
  #define _MEMORY_A2_PIN_STATE 0  // Address pin 2 state
  
  #define _WP_DISABLE  // Write Protect disable macro
  
  #define _WRITE_PROTECT_PORT  GPIOA  // Connected Port for 'Write Protect'
  #define _WRITE_PROTECT_PIN   9      // Connected Pin for 'Write Protect'
  

3. Config I2C and initialize it.

4. Using initialize methods for initialize hardware and chipset, for example:

I2C_Memory_Init();

5. Using operation methods, for example:

int main(void)
{
   
   I2C_Memory_Init();   // Initialize
      
   while()
   {
     I2C_Memory_SingleWrite(0, 'a', 100);
     
     if (I2C_MemoryIsReady(100) == 0)
     {
       // Memory error
     }
     
   }
}
   

Supported Chipset:

• AT24 Series
• AT25 Series

How transfer data from PC to EEPROM

Hello!

I2C EEPROM ICs are very popular. Thank you for your code.

There is another interesting open source project about How transfer data from PC to EEPROM IC. I think it is great idea to add information about this project to description of repo.
