switched to STM32

A project log for (BCD)WristWatch

It all started with the idea of a PCB which could display the time in BCD code....

since the ATMega328P has a lot of reserved pins there are not enough usable pins to
supply the BMA and the 42 LEDs for the analog Version (only one Pin was missing).  I switched to the STM32 Controller. But for simplicity i started with the Binary Version. To make the PCB look more like an actual PCB i also moved the BMA Sensor to the front of the Watch right next to the CPU.
