The is code snippet of I2C for STM32 use GPIO

Note: All VirtualI2C_s structure parameters of the function can be modified to point to VirtualI2C_s has speeded up access and execution speed

Usage

• ./test directory is a AT24XX EEPROM device access code

• Declare VirtualI2C variable and check the I2C bus if exist AT24XX device:

   VirtualI2C_s g_sVirtualI2c = {
   	{GPIOB, 10, 11},
   	I2C_STANDARD_100KHz,
   	0,
   	i2cDelay
   };
  
   at24cxxCheck();
   ...

• Please check for details the file ./test/hal_24cxx.c
