I2C_ReadRandom

The function I2C_ReadRandom reads one byte from a given i2c-address.

int I2C_ReadRandom(     
  UCHAR SlaveAddress, 
  UCHAR SubAddress
); 
int i2c_RandomByteRead(     
  UCHAR SlaveAddress, 
  UCHAR SubAddress
); 

SlaveAddress SlaveAddress of i2c-device.

SubAddress SubAddress of i2c-device.

If the function succeeds, the return value is the byte read from the i2c-device.

If the function fails, the return value is -1.

Issues following sequence:

1. Lock
2. Start
3. SlaveAddress with write-bit
4. SubAddress
5. SlaveAddress with read-bit
6. Read one byte
7. Stop
8. Unlock

This function calls I2C_Lock and I2C_Unlock to prevent multiple accesses to the i2c-bus. Don't lock access to i2c-bus prior to using this function!!
