Exemple d'utilisation du terminal comme afficheur, en C et sous CodeWarrior V10.
( Liaison série SCI <> port COM PC )
Windows 7 ne comporte plus Hyperterminal, sur l'exemple j'utilise TeraTerm
Pour l'utilisation de la fonction printf, j'ai modifié la librairie termio.h :
/******************************************************/
/** * @file termio.h
* Terminal: terminal low level functions.
* Note that the low level functionality is depending on * the hardware used (see implementation module termio.c),
* especially TERMIO_Init(). The provided implementation
* works in the simulator (component Terminal), but as
* well on most hardware. */

#ifndef TERMIO_H
#define TERMIO_H
#ifdef __cplusplus
extern "C" {
#endif
** * Sends a character to the terminal channel.
* @param ch Character to be sent to the terminal channel. */
void TERMIO_PutChar(char ch){ sci_tx(ch); }
/** * Receives a character from the terminal channel.
* @return The character received from the terminal channel. */
char TERMIO_GetChar(void){
char recept;
recept = sci_rx();
return recept; }
/** * Initializes the communication channel.
* It sets up the baudrate as well. Note that the implementation is
* heavily depending on the hardware used. */
void TERMIO_Init(void){ Init_SCI(); }
#ifdef _TERMIO_HAS_PUT_STRING_
/** * Writes a string at once (more efficient).
* @param p Pointer to the string to be written. */
void TERMIO_PutString(const char *p);
#endif
#ifdef __cplusplus
}
