Classic Snake game for the STM32 board

Hardware prerequisities

• stm32duino (should work on generic Arduino boards)
• Philips PCD8544 (Nokia 3310) LCD

Software prerequisities

• Arduino Software
• Arduino Core for STM32
• Adafruit PCD8544 Library
• Adafruit GFX Library
• SimpleTimer Library for Arduino
• Standard C++ for Arduino

Building and flashing

Just as with normal Arduino codes, build and flash it from the Arduino Software.

• Board: Generic STM32F103C series
• Variant: STM32F103C8 (20K RAM. 64K Flash)
• CPU Speed: 72MHz

Note

If using a different board, then change the configuration and modify the pins accordingly. For the STM32 board the following changes are necessary:

Adafruit_PCD8544.h:

#define PCD8544_SPI_CLOCK_DIV SPI_CLOCK_DIV4 -> #define PCD8544_SPI_CLOCK_DIV SPI_CLOCK_DIV8

#ifdef __SAM3X8E__
typedef volatile RwReg PortReg;
typedef uint8_t PortMask; -> typedef uint32_t PortMask;
#else
typedef volatile uint32_t PortReg;
typedef uint8_t PortMask; -> typedef uint32_t PortMask;
#endif
