This is a simple raycasting engine implemented in C for the ESP32 microcontroller, designed to work with the ST7789 display driver. It also compiles for other platforms with the raylib library.
To use this code, you need to have the ESP-IDF development environment set up on your machine. Follow the official ESP-IDF documentation to install and configure the environment: ESP-IDF Getting Started Guide The development has been done using ESP-IDF v5.5.2
To compile and run the code on other platforms, you need to have the raylib library installed. Follow the official raylib documentation to install and configure the library: Raylib Installation Guide The development has been done using raylib v5.5
Windows is not supported at the moment.
To compile the code and run it, use the following command:
make run#define FB_DRAM // Define this flag to place the framebuffer in DRAM instead of IRAM.
// LCD configuration
#define LCD_W 240 // Active width of the display
#define LCD_H 135 // Active height of the display
// internal vram is usually 320×240 for T-Display, smaller screens should be offsetted
#define LCD_X_OFF 40 // display vram X offset
#define LCD_Y_OFF 53 // display vram Y offset
// LCD Pins
#define PIN_MOSI 19 // SPI MOSI pin
#define PIN_CLK 18 // SPI Clock pin
#define PIN_CS 5 // SPI Chip Select pin
#define PIN_DC 16 // SPI Data/Command pin
#define PIN_RST 23 // SPI Reset pin
#define PIN_BL 4 // SPI Backlight pin
#define SPI_CLOCK_SPEED (80 * 1000 * 1000) // SPI clock speed in Hz
// Key Pins
#define PIN_KEY_A 0 // Key A pin
#define PIN_KEY_D 35 // Key D pin
