NO , jim , you don't need to invent summary .. I'm only curious, and
try to find an i/o which work !
My first test is with my driver (kernel module). I toggle only DIO_0
(PB.0) , and it's does'nt work !
My 2nd test, was with the small user program I sent, to find a good
i/o,so to toggle all the i/o of DIO1 header and I find the DIO_7 (PB.7).
My 3nd test, was with my driver , to toggle the DIO_7, and it'work !
My 4th extra test, was to verify, the DIO_0, with a user program, so
to toggle only DIO_0(PB.0) and DIO_7(PB.7) and I have to notice that
DIO_7 toggle and not DIO_0 !!
I look for information un the ep9301 user manual and I find nothing. I
look also on the TS7300 shematic, and I can't explain it ... DIO_0
should be linked to PB.0.
Perhaps my approach seem you not be logic, but you can't explain why
it does'nt work !
