Posted on February 14, 2013 at 01:33 i failed in portc0 as input... as it has a output voltage of 2++ so i dont want to play tug of war with that voltage as I don't want to cause any damage so instead of pc0-pc7 i have used pc1-pc8 anyweyz instead i tried pc8 now heres another trivia my code is Data = 255 - (GPIOC ->IDR>>1 & 0x00FF) ; so in my portc.1-portc.8 heres my input ->00111111 I expect my data to be 3 but what comes out is 131 so there's an excess 128 when i try portc.1-portc.8 heres my input ->00111110 I expect my data to be 131 but what comes out is 3 so there's a missing 128 when i try portc.1-portc.8 heres my input ->11111111 I expect my data to be 0 but what comes out is 128 so there's an excess 128 my portc.8 is being inverted in nature.. is there something wrong with what i did?
