UART communicatoin between boards works
Temp Read with dht11 and arduino works
Temp read with dht11 and stm doesnt crash but not send messages to console
RGB LED works with PWM
probably need pull up resistor with dht11, message to console is sending
i think: 16 MHz SYSCLCK, 15 prescaler, period 65535 -> delay(#microseconds) to be checked
