Logging and settings

---

The device exposes two virtual UART ports. One for logging and one for shell.

Shell commands allow you to adjust parameters and save them permanently.

Essential shell commands:

---

* `bootloader` Reboot MCU to bootloader

* `help` Prints the help message.

* `joystick` Prints joystick position. Optionally, you can specify the number of samples to take.

* `params` Print current params

* `pause`  Suspends normal motor operations to set up parameters

* `reboot` Reboots the device

* `resume` Resumes normal motor operation

* `set center` Sets joystick central(neutral) position [0..359]

* `set pwm_min` Sets minimal pwm [0..99]

* `set dead_angle` Sets joystick dead angle [0..180]

* `set max_angle` Sets joystick max angle [0..180]
