Sangon Elettronica Port Devices Driver Download For Windows 10

  

Connecting to your Floureon IP camera. Try the following connection options in iSpy or Agent to connect to your Floureon IP camera.If an FFMPEG option is available we recommend you try that first as it will often be faster and include audio support. The package provides the installation files for SAMSUNG Mobile USB Serial Port Driver version 2.12.1.0. If the driver is already installed on your system, updating (overwrite-installing) may fix various issues, add new functions, or just upgrade to the available version. This is the quick start information for installation of the Windows drivers, the driver must be installed before you can use SDR Console. See: driver installation for latest information. Download the Windows drivers from Windows drivers as a ZIP file.

Gestione porta parallela da shell

Di seguito viene presentato un metodo per accedere alle varie linee di ingresso ed uscita presenti nella porta parallela tramite la shell bash di linux.
Tutto quello di cui abbiamo bisogno è un driver per la porta parallela che renda disponibili queste informazioni a livello utente, a tale scopo dopo alcune ricerche ho trovato il driver ppin scritto da Alexander Barton e disponibile sul suo sito web.
Il suo driver tuttavia, nella versione cc46065, permetteva solo di scrivere sulle linee dati della porta parallela, mentre per poter pilotare il mio programmatore ICSP avevo bisogno di poter leggere anche le altre linee di ingresso, quindi ho apportato alcune modifiche che permettono di visualizzare anche lo stato dei registri di stato e controllo della porta parallela.
Questa è la versione del file ppin.c da me modificato, visto il contributo banale da me portato a tale driver, ho lasciato invariato il nome dell'autore e tutto il resto:
* Parallel Port Pin driver for Linux 2.6: ppin
* This kernel module will register the /dev/ppin (10, 151)
* device which controls up to eight pins through the first
*
* Controlling the pins is as easy as 'echo Num State >/dev/ppin',
* where Num is 0 to 7 and State is one of 'H', 'L'.
* For example: 'echo 3 H >/dev/ppin' switches the 3rd pin on.
* You can read the status of the pins with 'cat /dev/ppin'.
* This program is free software; you can redistribute it and/or
* modify it under the terms of the GNU General Public License
* as published by the Free Software Foundation; either version
* 2 of the License, or (at your option) any later version.
* Authors: Alexander Barton, <[email protected]> (for Linux 2.6, 2009)
* This work is heavily(!) based on the 'devled' driver written by
* Konstantinos Natsakis, <[email protected]> (for Linux 2.2/2.4).

module_exit(ppin_cleanup);
Il driver è stato scritto per un kernel 2.6, ma io riesco a compilarlo e caricarlo anche su un kernel 3.1.

sudo make install
sudo insmod /lib/modules/$(uname -r)/extra/ppin.ko


PIN #: 0 1 2 3 4 5 6 7
State: L L L H H H H L

Ora è ancora possibile inviare comandi alla porta parallela,
Ad esempio se voglio portare allo stato logico alto il pin 2 della porta parallela che corrisponde al bit 0 del registro dati:
Mentre se voglio leggere il valore del pin 10 della porta parallela (ACK), che corrisponde al bit 6 del registro di stato:
Il mio GuruProg, utilizza le linee dati 0, 1, 2 e 3 per la scrittura e la linea ACK per la lettura ( pin 2,3,4,5,10 della porta parallela ), con questo driver riesco a pilotarlo con dei semplici script bash ed a programmare diversi dispositivi che comunicano tramite bus I2C come memorie 24cxx, microcontrollori pic ecc...
