# Minesweeper on the Fruit Jam and Metro RP2350
## Overview
This project demonstrates how to run the [Minesweeper](https://en.wikipedia.org/wiki/Minesweeper_(video_game)) logic puzzle game on the Metro RP2350 using the mouse attached through its USB host pins. It includes controls such as dropdown menus in order to set the difficulty and confirm a reset. This is a take on the classic game of Minesweeper that has been implemented on many systems. It allows right clicking to set flags on known mines or tag squares as unknown with a question mark square.
The game is displayed on any HDMI compatible display using the HSTX ribbon connector on the Metro and a DVI breakout.
## Parts
This project can be done with either the Fruit Jam or the Metro RP2350.
If using the Fruit Jam, you will need:

# Minesweeper on the Fruit Jam and Metro RP2350
## Preparing the Metro RP2350
Primary: If you have a Fruit Jam instead of a Metro RP2350, you can go to the next page.
The USB Host port is the only part of this project that required soldering and only if you use standard header pins.
The USB Host pin connections are highlighted on the Metro image to the left. You will need a small piece of 0.1 inch male header, with 4 pins, to fit the holes.
You can cut header with diagonal cutters or break them with pliers or even your fingers. Just be sure to wear eye protection as they can fly when cut.
Put the short end of the header into the holes in the Metro marked USB Host.
If you are using solderless header then they are press fit into the holes. You will need some pressure to get them in if they are the Press-Fit version, pliers will be required. While they are designed to make electrical contact, you might want to solder them to be sure.
If using standard header, secure them with putty, blutack, tape, etc.
Turn the Metro over and you should see the header barely poking out of the bottom of the board. If the pins stick through a great deal you may have the header pins upside down, double check the short end is sticking into the board.
Solder the 4 pin "nubbins" to the board.
Turn the board over and remove the material securing the pins. Now there is a new 4-pin header.
Get the USB Host cable and wire as follows:
**GRD** to **Black**
**D+** to **Green**
**D-** to **White**
**5V** to **Red**
## HSTX Connection to DVI
Get the HSTX cable. Any length Adafruit sells is fine. CAREFULLY lift the dark grey bar up on the Metro, insert the cable silver side down, blue side up, then put the bar CAREFULLY down, ensuring it locks. If it feels like it doesn't want to go, do not force it.
Do the same with the other end and the DVI breakout. Note that the DVI breakout will be inverted/upside down when compared to the Metro - this is normal for these boards and the Adafruit cables.

## CircuitPython for the Metro RP2350
[CircuitPython](https://github.com/adafruit/circuitpython) is a derivative of [MicroPython](https://micropython.org) designed to simplify experimentation and education on low-cost microcontrollers. It makes it easier than ever to get prototyping by requiring no upfront desktop software downloads. Simply copy and edit files on the **CIRCUITPY** drive to iterate.
## CircuitPython Quickstart
Follow this step-by-step to quickly get CircuitPython running on your board.
[Download the latest version of CircuitPython for this board via circuitpython.org](https://circuitpython.org/board/adafruit_metro_rp2350/)
**Click the link above to download the latest CircuitPython UF2 file.**
Save it wherever is convenient for you.
To enter the bootloader, hold down the **BOOT/**** BOOTSEL button**(highlighted in red above), and while continuing to hold it (don't let go!), press and release the**reset button**(highlighted in red or blue above). **Continue to hold the BOOT/BOOTSEL button until the RP2350 drive appears!**
If the drive does not appear, release all the buttons, and then repeat the process above.
You can also start with your board unplugged from USB, press and hold the BOOTSEL button (highlighted in red above), continue to hold it while plugging it into USB, and wait for the drive to appear before releasing the button.
A lot of people end up using charge-only USB cables and it is very frustrating! **Make sure you have a USB cable you know is good for data sync.**
You will see a new disk drive appear called **RP2350**.
Drag the **adafruit-circuitpython-_boardname_-_language_-_version_.uf2** file to **RP2350.**
The **RP2350** drive will disappear and a new disk drive called **CIRCUITPY** will appear.
That's it, you're done! :)
## Safe Mode
You want to edit your **code.py** or modify the files on your **CIRCUITPY** drive, but find that you can't. Perhaps your board has gotten into a state where **CIRCUITPY** is read-only. You may have turned off the **CIRCUITPY** drive altogether. Whatever the reason, safe mode can help.
Safe mode in CircuitPython does not run any user code on startup, and disables auto-reload. This means a few things. First, safe mode _bypasses any code in_ **boot.py** (where you can set **CIRCUITPY** read-only or turn it off completely). Second, _it does not run the code in_ **code.py**. And finally, _it does not automatically soft-reload when data is written to the_ **CIRCUITPY** _drive_.
Therefore, whatever you may have done to put your board in a non-interactive state, safe mode gives you the opportunity to correct it without losing all of the data on the **CIRCUITPY** drive.
### Entering Safe Mode
To enter safe mode when using CircuitPython, plug in your board or hit reset (highlighted in red above). Immediately after the board starts up or resets, it waits 1000ms. On some boards, the onboard status LED (highlighted in green above) will blink yellow during that time. If you press reset during that 1000ms, the board will start up in safe mode. It can be difficult to react to the yellow LED, so you may want to think of it simply as a slow double click of the reset button. (Remember, a fast double click of reset enters the bootloader.)
### In Safe Mode
If you successfully enter safe mode on CircuitPython, the LED will intermittently blink yellow three times.
If you connect to the serial console, you'll find the following message.
```terminal
Auto-reload is off.
Running in safe mode! Not running saved code.
CircuitPython is in safe mode because you pressed the reset button during boot. Press again to exit safe mode.
Press any key to enter the REPL. Use CTRL-D to reload.
```
You can now edit the contents of the **CIRCUITPY** drive. Remember, _your code will not run until you press the reset button, or unplug and plug in your board, to get out of safe mode._
## Flash Resetting UF2
If your board ever gets into a really _weird_ state and CIRCUITPY doesn't show up as a disk drive after installing CircuitPython, try loading this 'nuke' UF2 to RP2350. which will do a 'deep clean' on your Flash Memory. **You will lose all the files on the board** , but at least you'll be able to revive it! After loading this UF2, follow the steps above to re-install CircuitPython.

# Minesweeper on the Fruit Jam and Metro RP2350
## Software Setup
## CircuitPython Usage
To use the game, you need to add the game program files to the **CIRCUITPY** drive. The game consists of a handful of Python files and bitmaps.
Thankfully, installing everything be done in one go. In the code block below, click the **Download Project Bundle** button to download the necessary libraries and game files in a zip file.
Connect your board to your computer via a known good data+power USB cable. The board should show up in your File Explorer/Finder (depending on your operating system) as a flash drive named **CIRCUITPY**.
Extract the contents of the zip file, copy the **lib** directory files to **CIRCUITPY/lib**. Copy the entire contents of the appropriate CircuitPython folder to your **CIRCUITPY** drive. The program should self start.
## Drive Structure
After copying the files, your drive should look like the listing below. It can contain other files as well, but must contain these at a minimum.
## Code
The **code.py** for the game is shown below.
https://github.com/adafruit/Adafruit_Learning_System_Guides/blob/main/Metro/Metro_RP2350_Minesweeper/code.py
# Minesweeper on the Fruit Jam and Metro RP2350
## Code Overview
The code for minesweeper is divided into 4 files: The main code (which glues everything together), the game logic, and a couple of custom UI elements. In many games, I try and separate the game logic from the user interface, which makes porting to other platforms much easier.
### Main Code
The main **code.py** file handles setting everything up, responding to the user inputs, and updating the User Interface. Everything within the UI is handled by CircuitPython's [displayio](https://docs.circuitpython.org/en/latest/shared-bindings/displayio/index.html). There are some custom controls such as dialogs made using the [TextBox](https://github.com/adafruit/Adafruit_CircuitPython_Display_Text/blob/main/adafruit_display_text/text_box.py) component of the [adafruit\_display\_text](https://github.com/adafruit/Adafruit_CircuitPython_Display_Text) library as well as an event button and menu control, which will be looked at in more detail below. This file is fairly self explanatory with comments throughout the file.
The setup mainly consists of setting up the game board, setting up the menus and dialogs, and setting up the mine count and time labels.
https://github.com/adafruit/Adafruit_Learning_System_Guides/blob/main/Metro/Metro_RP2350_Minesweeper/code.py
### Game Logic
The game logic handles the Minesweeper game logic. Much of the logic was borrowed from the [CircuitPython Minesweeper Game](https://learn.adafruit.com/circuitpython-pyportal-minesweeper-game) guide, which is a basic version of Minesweeper designed for the PyPortal with touch input. This version adds difficulty levels as well as a timer.
This file starts by defining the difficulty levels. Each difficulty level has a label (which automatically appears in the Difficulty menu), the size of the grid, and the number of mines. Feel free to add your own additional levels, but keep in mind, the maximum grid size is limited by the screen size to 20x14. The mine count will need to be at least 10 and no more than `grid_width - 1 * grid_height - 1`, which effective makes 4x5 the smallest possible grid size.
```auto
DIFFICULTIES = (
{
'label': "Beginner",
'grid_size': (8,8),
'mines': 10,
},
{
'label': "Intermediate",
'grid_size': (14, 14),
'mines': 30,
},
{
'label': "Expert",
'grid_size': (20, 14),
'mines': 58,
},
)
```
The choices are automatically added to the Difficulty menu in the order in which they appear in the `DIFFICULTIES` list. Also, having more than about 14 level choices may cause the menu to be longer than the screen height, which would make the choice unavailable. Here are the default difficulty settings.
https://github.com/adafruit/Adafruit_Learning_System_Guides/blob/main/Metro/Metro_RP2350_Minesweeper/gamelogic.py
### Event Button
The event button builds on the [standard button](https://github.com/adafruit/Adafruit_CircuitPython_Display_Button/blob/main/adafruit_button/button.py) available in the [adafruit\_button](https://github.com/adafruit/Adafruit_CircuitPython_Display_Button) library. It adds the option to specify a callback function when the button is clicked as well as some mouse handling code so that a click is only registered if another element wasn't already selected and the click is within the boundaries of the button. This way if another UI element is selected and the mouse is dragged onto the button, it is handled properly.
https://github.com/adafruit/Adafruit_Learning_System_Guides/blob/main/Metro/Metro_RP2350_Minesweeper/eventbutton.py
### Menu
The menu is used for handling the options at the top. This allows selecting the difficulty or resetting the game. The reason that the reset option is inside a menu is to help avoid accidentally clicking the button when playing with some of the larger game grids. It was cleaner to implement this way than a dialog that popped up asking to confirm.
The menu class is really just a container for the submenus with similar mouse handling code to that of the event button. When one of the menu items is clicked (which is really just an event button), the submenu's contents are drawn below it, which also consists of event buttons. Each submenu is in a separate displayio to help with controlling the visibility.
Submenu items can also be "selected", which highlights the selected item in green. This is useful for showing the currently selected difficulty level.
https://github.com/adafruit/Adafruit_Learning_System_Guides/blob/main/Metro/Metro_RP2350_Minesweeper/menu.py
# Minesweeper on the Fruit Jam and Metro RP2350
## Usage
To play Minesweeper is simply a matter of loading it up. The goal is to correctly identify all of the mines using a combination of logic and pattern recognition. When squares without mines are clicked with the mouse, they are revealed. If the square contains a mine, all mines will be shown and the game is over. If there isn't a mine where you clicked, it will behave in a couple of different ways depending on whether it is next to a mine. If the square is next to a mine, it will have a number that indicates the number of mines adjacent to the square; that is any mines to the side of, above, below, or diagonally.
If the square is not next to a mine, it will appear as blank. If there are other blank squares next to the clicked square, they will also be revealed. The first click will never be a mine because the mine placements are not generated until after the first click.
You can also right-click the mouse on any square to flag it as a mine. Right-clicking a second time will turn it into a question mark in case you aren't sure between a couple of different squares. Flagged mines don't respond to a normal click. Question marked mines still act like normal squares.
## Strategies
The basic strategy is to start by clicking any square. Some people prefer to click near the edge and some people in the middle, however the middle tends to be the best place to start due to more possible openings.
Once you have clicked on the opening square, your next move will depend on what you clicked on. If you are lucky, a bunch of squares will be revealed and you can continue with pattern recognition strategies. If not and the square is a number, you will likely need to take a guess as to the next square you click.
Flag mines that you are certain about. This prevents accidentally clicking and decrements the mine counter so you know how many unmarked mines are remaining.
If you are unsure between a couple of different spots, using the question mark will come in handy. It will not reduce the mine counter and the square can still be clicked.
Save any squares you are uncertain about until the end. Watch the mine counter too because it can also help determine between a uncertain squares based on how many are left.
Because Minesweeper has been around awhile, you can find many more strategies on the internet.
