Hi Greg,
hi all in the mailing list
first, thanks for the reply.
I have succefully integrated the 0.90 calibration feature into my
microwindows 0.89. On PC side, with the new modified libnano-X, I have
compiled the nxcal.c and
got the binary. It works and it generates the "nxcal.dat" file.
Then I've successfully cross-compiled it with arm-linux-gcc and tested it on
the board.
The problem is that on the TFT the cross and the msg ("Microwindows
Calibration" - "Touch the cross hairs firmly to"- "calibrate your handheld")
are correctly displayed but if I touch the cross hairs nothing happens as
there is no event.type = GR_EVENT_TYPE_MOUSE_POSITION
if (event.type == GR_EVENT_TYPE_MOUSE_POSITION)
if (handle_pos(&event.mouse)) {
calculate_transform(trans);
return; }
Of course, no nxcal.dat file is created. Any help?
An other question. I have investigated in the 090 project any reference to
"nxcal.dat" ***without*** result. So, in which way the values saved in the
.dat file are used by the other application? Those values are corrections to
the mouse position, right? a sort of compensation... any help? any reference
of "how to use" application? I also figure that on PC side there is no wrong
mouse position...
For the problem with cross-compile for ARM the microwindows 0.90, the error
was:
In file included from /usr/include/string.h:375,

For my problem accessing the Microwin CVS it should be a problem of our LAN,
I hope I will solve it soon...
Thanks in advance for any help and suggestions.
