====== GPIO over MCU ======

These two ports are directly connected to the [[stm32:peripherals:gpio|GPIO ports A and B]] on the microcontroller. \\
All [[stm32:peripherals:gpio#alternate_functions|functions]] of theese GPIO ports are available. \\ \\

> {{ctboard:ctboard_mode_no.svg?48px }} This functionality is independent of the CT Board mode.
> Supported modes: Available in all [[ctboard:mode_switch|modes]]. 
\\

===== Programming Example =====

To configure and use these Ports, setup [[stm32:peripherals:gpio|GPIO port A / B]] on the microcontroller. \\ \\

===== Diagram =====

> Only pins 0..11 are connected to P5 / P6! The other 4 pins are used for 5V, 3.3V and GND.
