## GPIO Pins
## GPIO Pins
The GPIO pins, even though rather simple, were a little bit confusing in the first place. The technical drawings of the Raspberry Pi has linearly incrementing pin numbers. However, this numeration is different at kernel level. Since we did not expect that, we spent several hours of checking all other code snippets before we considered that our error must lie there. When we discovered the correct pin numbers, we were also drawing the cirquit diagram to make our decision about which pins to use final. We also defined some macros (found in [src/include/defines.h](/fk16790/SevenSegController/src/include/utils.h)) in order to access the pins easier.
