hi
i have the above board and this are the pins:
my question : there are a few pins which are bound to different things like IO8 is U1RXD as also b(lue)0 for parallel output pin for display.
So it is possible to share pins between different functions? The pins on the right like SPI 2 is for the TFCard as also for SPI. So could i use SPI (an 4pin expansion on the board) and the TFCard simultaneously?
Someone any ideas
regards
hape
