The Arm Cortex M4 is a powerful 32-bit microcontroller that is significantly more capable than traditional 8-bit microcontrollers like the ATMega-Series by Atmel or the PIC-Series by Microchip. However, getting started with this device is a bit more involved compared to more simpler microcontrollers. Thus, I wrote an introductory tutorial (in German) for the Cortex M4 that not only guides you through the step-by-step setup procedure this controller requires, but also teaches you how to read and use the extensive documentation that comes with this device. You can find the tutorial on GitHub.
