Hi all,
|
|
|
|
|
|
This module provide a serial interface to use your
|
|
IUU unit in phoenix mode. Loading this module will
|
|
bring a ttyUSB[0-x] interface. This driver must be
|
|
used by your favorite application to pilot the IUU
|
|
|
|
This driver is still in beta stage, so bugs can
|
|
occur and your system may freeze. As far I now,
|
|
I never had any problem with it, but I'm not a real
|
|
guru, so don't blame me if your system is unstable
|
|
|
|
You can plug more than one IUU. Every unit will
|
|
have his own device file(/dev/ttyUSB0,/dev/ttyUSB1,...)
|
|
|
|
|
|
|
|
How to tune the reader speed ?
|
|
|
|
A few parameters can be used at load time
|
|
To use parameters, just unload the module if it is
|
|
already loaded and use modprobe iuu_phoenix param=value.
|
|
In case of prebuilt module, use the command
|
|
insmod iuu_phoenix param=value.
|
|
|
|
Example:
|
|
|
|
modprobe iuu_phoenix clockmode=3
|
|
|
|
The parameters are:
|
|
|
|
parm: clockmode:1=3Mhz579,2=3Mhz680,3=6Mhz (int)
|
|
parm: boost:overclock boost percent 100 to 500 (int)
|
|
parm: cdmode:Card detect mode 0=none, 1=CD, 2=!CD, 3=DSR, 4=!DSR, 5=CTS, 6=!CTS, 7=RING, 8=!RING (int)
|
|
parm: xmas:xmas color enabled or not (bool)
|
|
parm: debug:Debug enabled or not (bool)
|
|
|
|
- clockmode will provide 3 different base settings commonly adopted by
|
|
different software:
|
|
1. 3Mhz579
|
|
2. 3Mhz680
|
|
3. 6Mhz
|
|
|
|
- boost provide a way to overclock the reader ( my favorite :-) )
|
|
For example to have best performance than a simple clockmode=3, try this:
|
|
|
|
modprobe boost=195
|
|
|
|
This will put the reader in a base of 3Mhz579 but boosted a 195 % !
|
|
the real clock will be now : 6979050 Hz ( 6Mhz979 ) and will increase
|
|
the speed to a score 10 to 20% better than the simple clockmode=3 !!!
|
|
|
|
|
|
- cdmode permit to setup the signal used to inform the userland ( ioctl answer )
|
|
if the card is present or not. Eight signals are possible.
|
|
|
|
- xmas is completely useless except for your eyes. This is one of my friend who was
|
|
so sad to have a nice device like the iuu without seeing all color range available.
|
|
So I have added this option to permit him to see a lot of color ( each activity change the color
|
|
and the frequency randomly )
|
|
|
|
- debug will produce a lot of debugging messages...
|
|
|
|
|
|
Last notes:
|
|
|
|
Don't worry about the serial settings, the serial emulation
|
|
is an abstraction, so use any speed or parity setting will
|
|
work. ( This will not change anything ).Later I will perhaps
|
|
use this settings to deduce de boost but is that feature
|
|
really necessary ?
|
|
The autodetect feature used is the serial CD. If that doesn't
|
|
work for your software, disable detection mechanism in it.
|
|
|
|
|
|
Have fun !
