Hi Benjamin,

do you want I install a wiki so that we can both modify the USB doc ?
Or, is the SVN access enough for you ?

Hi Benjamin,

while transferring variables, buffer request/negotiation seems not to be
compulsory between each variable. But, a pause (50 ms) is required
otherwise transfer fails.

SVN is fine.

Incidentally, I have an idea about the BB00 packet.  Its contents seem to
be used as a timeout.  Perhaps it simply means "wait for X milliseconds
for the next packet," and it's sent whenever the calculator expects to
take a long time to respond.  That would seem to make sense in the
contexts where it is used.

[TiLP-devel] TiLP2 & TI84+ USB: beta release

[Romain <ro...@li...>]

Hi,

on the TiLP news page, I have released an experimental/beta release of
TiLP-II with partial TI84+ USB support (all transfers are supported except
for FLASH ones).

Please keep in mind this release may crash or corrupt your data. Use it
with care !

Great. I'll test that right now.

By the way, is it possible to anonymously checkout from the svn repository?=
 It
would be easier than downloading the entire tarballs whenever there is a new
snapshot.

[TiLP-devel] TiLP2 & TI84+ USB: beta release: issues

[Alexandre S. <st...@gm...>]

Hi,

I'm getting some trouble trying to make my TI84+ and DirectUSB work with Ti=
LP.

First, when I start as a normal user I get:

---------------------------------------------------------------------------=
---
ticables-INFO: Check for lib-usb usability:
ticables-INFO:     usb filesystem (/proc/bus/usb): mounted
ticables-INFO:     node /proc/bus/usb/devices: exists
ticables-INFO:     permissions/user/group: -r--r--r-- root root
ticables-INFO:     is user can r/w on device: no
ticables-INFO:     are others can r/w on device: no
ticables-INFO:     is the user 'alex' in the group 'root': no
ticables-INFO:     =3D> you should add your username at the group 'root' in
'/etc/group'
ticables-INFO:     =3D> you will have to restart you session, too
tilp-INFO: Msg: illegal operation or argument.
Cause: the program which uses this library is buggy. Fire-up the developer!
---------------------------------------------------------------------------=
---

This is probably due to my system configuration, though. Anyway, I tried Ti=
LP
as root. I have permissions to access usb devices,...  But when I change the
device settings to DirectUSB, with any port, and TI84+, I getthis error:

---------------------------------------------------------------------------=
---
Msg: illegal operation or argument.
Cause: the program which uses this library is buggy. Fire-up the developer!
System: Inappropriate ioctl for device (errno =3D 25)
---------------------------------------------------------------------------=
---

I compiles with logging support, but there's nothing in ~/ticables.log.

Here's the output of lsusb:

---------------------------------------------------------------------------=
---
# lsusb
Bus 001 Device 003: ID 0451:e003 Texas Instruments, Inc.=20

I think so. Perms are r only according to your log. They should be rw.
