void usart_clear_structure

(

rs232_struct_delete

rs232_del

)

usart_printf(): This function is called to send formatted bytes via USART

This function is called on usart as an usart formatted writing mechanism

Parameters:

void

Returns:

void usart_clear_structure(): This function is called to clear working parameters of RS232 This function is called to initialize the structure

Parameters:

rs232_del

(which should we delete)

Returns:

void

int usart_write

(

buffer

)

usart_write(): This function is called to send bytes via USART

This function is called on usart as an usart writing mechanism
only called when the first character is sent of a string

Parameters:

buffer

The Buffer we want to write

Returns:

1 on SUCCESS, -1 if FAILS (sending data to big)
