How to use this library

The Buffer library can be used as follows:

1. Add .h and source file in project.

2. Config buffer options in 'buffer_conf.h' header, for example:

• Options:

  #define _BUFFER_LENGTH        10
  #define _NUMBER_OF_OVERFLOW   5

• Parameters:
  • _BUFFER_LENGTH : Length of buffer
  • _NUMBER_OF_OVERFLOW : Number of overflows

3. Create Buffers and initialize it, for example:

• Example:

  Buffer_TypeDef serialDataBuff;
  Buffer_TypeDef sensorDataBuff;
   
  Buffer_Init(&serialDataBuff);
  Buffer_Init(&sensorDataBuff);
   

4. Using operation methods for manage data, for example:

int main(void)
{
   
   int nmbOfData = 0;
      
   Buffer_TypeDef serialDataBuff;
   Buffer_TypeDef sensorDataBuff;
   
   Buffer_Init(&serialDataBuff);
   Buffer_Init(&sensorDataBuff);
      
   while()
   {
     Save_In_Buffer(&serialDataBuff, 'a');
     Save_In_Buffer(&sensorDataBuff, 15);
     
     nmbOfData = Available_In_Buffer(&serialDataBuff); /* nmbOfData is number of available data in buffer */
     
     if (nmbOfData > 5)
     {
       Clean_Buffer(&serialDataBuff);
     }
     
   }
}
   

Buffer Type:

• Linear
• Circular
