int main ( void  )

Main function, execution starts here. RS232 is used to input/output information. The example lets you issue the following commands on RS232 using POSIX interfaces (open, read, write, close):

  • read a file from the memory files system;
  • concatenate a file to an existing one;
  • copy the content of a file to a new one.

Connect USART_1 to your serial port via a standard RS-232 D-SUB9 cable Set the following settings in your terminal of choice: 57600 8N1
