So, when the shuttlexpress.c was written, how were the number of packets it uses determined? And how are the bit mask names determined?

I expect that Seb put in HAL pins that reported the raw values, and stared intently at the numbers while operating the device.

I am working on generalising the driver, but not very rapidly.

As I said, just try changing the product ID and see if you end up with something that nearly works, but with only 4 buttons active.

Andy, I tried this and at the point I get to the ./auto gen.sh, it says no such file or directory?

Ah, sorry, you need to be in the src directory.

OK, now I get hung up at make.

It says: Makefile:55: Make file.inc no such file or directory. Makefile:66: *** Make file.inc must specify RTPREFIX and other variables. Stop.

Did you ./configure?

Yes.

Could you give me the instructions again referencing there proper directory structure? I am not certain I was in the proper directory.

You need to be on linuxcnc-dev/src

(Assuming you have put the git repository in linuxcnc-dev)

Then for testing.

./autogen.sh
./configure
make
sudo make setuid

That will create a run-in-place config, or it should tell you why it hasn't.

To use the run-in-place version you just compiled you need to move down a level to the linuxcnc-dev directory, then

. ./scripts/rip-environment

(Yes, that is dot space dot slash)

Then start linuxcnc or halrun from the same command prompt as you just ran the rip-environment script.
