## Buttons Configurations and Functions with Ports
#### Ports
* nRF Port: Connect to a nRF modules to have wireless control of the WB. (Instead we are using Bluetooth currently.)
* SWD Port: For code flashing to the Garuda. Most of the time we just have to flash once before used.
* UART Port: Connect a Can wire (since the T and R port here is flipped) to the WB to control the WB, or connect to a Bluetooth modules to control the WB. (We are currenly using Bluetooth.)
* Toggle: A switch. (HW has not yet soldier this on to our Garuda. Actually I am planning to use this to switch between Manual mode and Auto mode.)
#### Buttons
* **Rst_MB**: I don't know what is the use of this button Lol. (From what I have read from the code, this should be the reset button for the toggle. But I am not sure how its works exactly.)

* **TopLeft**: Press to turn the TFT on the mainboard to the previous page.

* **TopRight**: Press to turn the TFT on the mainboard to the next page.

* **Up**: Click to jump to the next state of the whole sequence. The whole sequence would be:
  1. Move the WB from the corner to the Start Zone which the WB will not be counted as violation. The magazine will be lifted. Arrows with ID.1 and ID 3 will be loaded by the two shooters.
  2. Move the WB from the Start Zone to Point A which is the first shooting point.
  3. Move the WB from Point A to Point C which is in front of the rack to load arrows.
  4. Move the WB from Point C to Point D which is the second shooting point.
  5. Move the WB from Point D to Point C to load arrows again.
  6. (Move the WB from Point C to Point D but not yet written to the code.)
* **Left**: Click to jump to the next sub-state for each shooting point (Point A and Point D).
