simple IN/OUT commands. The following lines show an example how to
do this. (The GPIO is
open drain)
GPIO0…..GPIO7 bit0……bit7
-o 4E 87 ;enter configuration
-o 4E 87
-o 4E 07
-o 4F 07 ;enale GPIO function
-o 4E 30
-o 4F 10 ;enable GPIO configuration
-o 4E F0
-o 4F xx ;set GPIO as input/output; set ‘1’ for input,’0’for
output
-o 4E F1
-o 4F xx ;if set GPIO’s as output,in this register its value can
be set
Optional :
-o 4E F2
-o 4F xx ; Data inversion register ; ‘1’ inverts the current valus
of the bits ,’0’ leaves them as they are
-o 4E 30
-o 4F 01 ; active GPIO’s
