Title (EN) EXTERNAL MICROCONTROLLER COMMUNICATIONS
(FR) COMMUNICATIONS DE MICROCONTRÔLEUR EXTERNE
Abstract:
(EN) Messaging between an ultra-tag and external microcontroller. In an embodiment, a transmitting device is communicatively connected to a receiving device by a clear-to-communicate line and request line. When data to be transmitted has normal priority, the transmitting device detects whether the clear-to-communicate line indicates that the receiving device is available, indicates a request to transmit on the request line if so, waits until the receiving device is available and then indicates a request to transmit on the request line if not, after indicating a request to transmit, transmits the data when the clear-to-communicate line indicates that the receiving device is unavailable, and, after transmitting the data, releases the indication of the request to transmit on the request line. On the other hand, when the data has high priority, the transmitting device indicates a request to transmit on the request line, regardless of an indication on the clear-to-communicate line.
(FR) L'invention concerne une messagerie entre une ultra-étiquette et un microcontrôleur externe. Dans un mode de réalisation, un dispositif de transmission est connecté en communication à un dispositif de réception par une ligne prête à communiquer et une ligne de demande. Lorsque des données à transmettre ont une priorité normale, le dispositif de transmission détecte si la ligne prête à communiquer indique que le dispositif de réception est disponible, indique une demande de transmission sur la ligne de demande si tel est le cas, attend que le dispositif de réception soit disponible et indique ensuite une demande de transmission sur la ligne de demande si tel n'est pas le cas, après avoir indiqué une demande de transmission, transmet les données lorsque la ligne prête à communiquer indique que le dispositif de réception n'est pas disponible et, après la transmission des données, libère l'indication de la demande de transmission sur la ligne de demande. D'autre part, lorsque les données ont une priorité élevée, le dispositif de transmission indique une demande de transmission sur la ligne de demande, indépendamment d'une indication sur la ligne prête à communiquer.
