using a serial port

Due to non working usb-uart plugs, I used what I had : an orange pi pc, running armbian. This allowed me to configure 3 serial ports.

Later on in my project I configured a stm32f103c6 to be used as an uart bridge.

I use armbian on a orange pi.

sudo armbian-config

In the Armbian configuration utility, navigate to System > Hardware and select the appropriate option to apply device tree overlays.
