Tic-tac-toe Game Based on STONE TFT LCD and STM32
Summary
Tic-tac-toe is a game played on a 3 by 3 grid, similar to gobang. It gets its name because the board generally does not draw borders and the grid lines are arranged into tic-tac-toe. The tools needed for the game are only paper and pen. Then, two players representing O and X take turns to leave marks on the grid. Any three marks form a straight line, which is the winner.
This article is to use microcontroller STM32 and STONE LCD display to develop a simple tic-tac-toe game.
Materials required for the experiment
The system principle
Specify the first tap on the screen must be O, the second tap on the screen is X, has been doing this cycle. Set 8 arrays to store the number of O and X in each row, column and diagonal of each grid, as long as there are three of the same mark is the victory, then there will be a flashing red box to prove the victory of the row, column or diagonal, and then tap reset to start the game again.
The following is the flow chart :

(B) STM32 board
Using a STM32 board, the chip of the STM32 is CKS32F303.
The STM32 family of ARM Cortex-M0, M0+, M3, M4 and M7 cores is designed for embedded applications requiring high performance, low cost and low power consumption.
- 2.0V-3.6V power supply
- 5V compatible I/O pins
- Excellent safe clock mode
- Low power mode with wake-up function
- Internal RC oscillator
- Embedded reset circuit
- Operating temperature range.
- -40°C to +85°C or 105°C
System software design
The development process of STM32 and STONE LCD display
1: create the project and load the required pictures into the project.
2: use the Stone-designer software to create, dynamically associated relationships; the main controls are: “Button”, “image”;
3: software simulation and compilation to generate executable files.
4: the LCD display is connected to the PC via USB and copy the executable file to the screen.
First create a new project as shown below.
Secondly, import all the images into the resource
Then, set button controls to each grid and make the buttons invisible.
Don’t forget to set the reset button!
The finished effect is shown below:
After that, add image controls to each grid in the same way, and set them all to white images.
Finally add the gif control and set it to invisible.
The parts of finished effect are shown below:
