Extension of mplay-driver for MonCaso 312/320

Hi!

This is a re-send of my e-mail from 2011-10-24, as there has been no reaction so far...

Here comes a modification for the mplay-driver. It extends the LIRC driver in order to support the case "MonCaso 312/320" with a built-in IR. Now, the wheel is supported, and the record button is recognised reliably. I have added a patch containing the following changes:
  • The IR receiver reports the wheel position by a two bit value, which is given in Gray code. The code is transported via two status lines of the serial port.
  • The driver establishes a thread polling the status lines, thus recognising wheel turn actions.
  • The thread reads from the serial port the remote control button presses, as it used to be the case before.
  • Wheel turn actions produce button presses for counterwise (0x81) and counter clockwise (0x80) turns.
  • Detected button presses are piped into the LIRC framework. The driver serves the write end, the LIRC framework has the read end.
  • Once a wheel action has been found, the driver temporarily reduces the polling period in order to get all wheel actions.
  • The driver uses an option "nowheel" appended to the driver parameter as in --driver="/dev/ttyUSB0,nowheel" or DRIVER="/dev/ttyUSB0,nowheel". This option switches off the creation of a polling thread. Instead, remote button presses are directly read from the serial  port, as it used to be the case before.
  • In order to avoid copy and paste, there is an init function for both mplay and mplay2.
The algorithms are explained in more detail in the source code comments.

I would be happy if the patch helps. Perhaps it is even a candidate to be included into the LIRC package. In addition, I added the forum post http://ubuntuforums.org/showpost.php?p=11385428&postcount=60, where you could reply to if you like to.

Unfortunately, only Ubuntu 11.04 is available for me, which is also the base for the patch.

Regards,
Wolfgang

Extension of mplay-driver for MonCaso 312/320: improved knob support [patch available]

Hi!

Here comes a LIRC patch with improved handling of the wheel/knob (turn and press actions). The patch removes knob bouncing effects, and has removed some subtle bugs when using wheel/knob and IR control in parallel.

It is available at http://ubuntuforums.org/showpost.php?p=12120799&postcount=99 (lirc-0.9.0.patch.gz).

The change has been in use for quite a while now, and works fine.

Please consider this e-mail as submission to include this patch into LIRC. I'd be glad if it were useful to some LIRC users.

Regards,
Wolfgang
