Descrizione Ordinata cronologicamente, centrata sui programmi di maggior successo, ricca di curiosita, la storia della televisione italiana viene riproposta aggiornata e arricchita da numerosi saggi. R., dalla Domenica sportiva a Mai dire gol, dal Karaoke al Grande fratello. Riproposta ora, riveduta, aggiornata e ampliata, la Storia di Aldo Grasso si conferma unica non solo per la quantita delle informazioni e per la profondita dell'analisi, ma anche per i suo punti di partenza:i 'testi' della TV, ovvero i programmi, dal Festivalbar a Sanremo a Rischiatutto, dal Musichiere alla Corrida, dall'Amico del giaguaro alle varie edizioni dei Promessi sposi, da Dallas a E. Quarta di copertina Quando nel 1992 usci la prima edizione di questa Storia della televisione italiana, non esisteva un'opera che raccontasse con tanta precisione e ampiezza l'evoluzione della televisione in Italia, dai primi esperimenti ai tempi del fascismo all'eta dell'oro della RAI, dal duopolio con le reti Mediaset all'emergere delle nuove tecnologie. QSerialPort class has constructor with signature QSerialPort(const QString &, QObject *), where QString may contain even device which is not included in the QList that QSerialPortInfo::availablePorts() returns.So I strongly recommend to take this approach.

Worked like a charm and the resulting driver worked out-of-box for my latest Raspbian Wheezy (4.1.7+ #817). I myself feared about RaspiComm RS-485 driver /dev/ttyRPC0 based on some forums complaints and not clear versioning, however found out, that the forum thread was heavy outdated. I succeeded to implement it based on kernel /dev/spidev0.0 only to find out that even this partially system driver supported solution is too slow for even 19 200 Bd speed (loosing about 5 characters on one received).

Do not try to implement communication with MAX3140 UART chip yourself (maybe except of asm based implementation, what is however most probably unnecessary exertion).

Getting back to document conclusions of my research on best practice of using RaspiComm RS-485 under Qt for anybody, who finds this thread useful (I expect many of it is valid for RS-232 on same board as well, did not test myself): Is there something in Qt (ready or WIP) about this (not to re-invent wheel) or is there some design skeleton/advice allowing eventually later extend QtSerialPort by this 'device'? (I am willing to contribute, should my development be evaluated as worth it.). Now I intend to develop some object for accessing RS-485 UART on RaspComm board (which is itself driven via SPI). SPI has same basic characteristics like serial port (baud rate, parity.) and even (kind of) asynchronous in/out driven by kernel device so this is why I expected same object could manage them both. (I am able to workaround based on QFile of course, however I would love to do things Qt way ).). What to do to make /dev/spidev0.0 appear in the list? Any clues and advices heartily welcome. I guess I can not (simply) use QSerialPort constructor with '/dev/spidev0.0' parameter before 'somehow' getting /dev/spidev0.0 accepted by QSerialPortInfo. Looks like your connection to Qt Forum was lost, please wait while we try to reconnect.ĭid anybody make QSerialPort(Info) work on /dev/spidev* kernel driver? I have running (visible, configured, operable via spidev_test.c) /dev/spidev0.0, however QSerialPortInfo::availablePorts returns list with just one member, for /dev/ttyAMA0. QextSerialPort add new BaudRate QextSerialPort add new BaudRate. Hey, I want to add the '691200' and '921600' baud rate to the Qextserialport baud rates list.
