I have plugged the pullup resister, but have no effect, the signal is
allways low.
Meanwhile i have try using the peek and peekpoke programs to change
the data and direction directily on GIO address similiar to my C code
posted before, and i noticed that the data value on register does not
change!!!!!
I have do this steps:
(Setting all pins has outputs by changing the value on PBDDR)
peekpoke 32 0x8084004 0xFF
(Read the value on PBDR)
peek 32 0x8084004
=> The value printed on screen is 0x18
(Write the new value on PBDR, 0xFF to set all 8 pins to high level)
peekpoke 32 0x8084004 0xFF
(Read the value on PBDR)
peek 32 0x8084004
=> The value printed on screen should be 0XFF, but still being 0x18
It seems that could not change the register value for some reason,
what implicates not changing the output... So the problem is not the
pullups resisters for now, but modifing register value. Do have any
ideas????
