Step 2: ⌨️ Coding

• Create cmatrix_esp32.h ✓ 49960e9 Edit

Create cmatrix_esp32.h with contents:
• Create a header file `cmatrix_esp32.h` to declare functions and macros specific to the ESP32 implementation.
• This file will include ESP-IDF (Espressif IoT Development Framework) headers necessary for OLED display control, GPIO handling, and other ESP32-specific functionalities.
• Define macros for OLED display dimensions and any other constants relevant to the ESP32 implementation.
• Declare initialization functions for the ESP32 hardware, such as `void esp32_init_display(void);` and `void esp32_deinit_display(void);`.
• Declare a function for rendering a frame on the OLED display, such as `void esp32_render_frame(const char* frame);`.

• Create cmatrix_esp32.c ✓ dde080f Edit

Create cmatrix_esp32.c with contents:
• Implement the ESP32-specific functionalities declared in `cmatrix_esp32.h`.
• Include `cmatrix_esp32.h` and relevant ESP-IDF headers for OLED display control and GPIO handling.
• Implement `esp32_init_display` to initialize the OLED display using ESP-IDF functions.
• Implement `esp32_deinit_display` to properly turn off and deallocate resources used by the OLED display.
• Implement `esp32_render_frame` to convert the matrix frame into a format suitable for the OLED display and render it using ESP-IDF functions.

• Modify cmatrix.c ✓ 0c90a7c Edit

Modify cmatrix.c with contents:
• At the beginning of `cmatrix.c`, conditionally include `cmatrix_esp32.h` if compiling for the ESP32. Use preprocessor directives to check if the ESP32 flag is defined, e.g., `#ifdef ESP32 #include "cmatrix_esp32.h" #endif`.
• In the main function or wherever the display initialization occurs, conditionally compile the ESP32 display initialization code using `#ifdef ESP32 esp32_init_display(); #endif`.
• Similarly, conditionally compile the code to deinitialize the ESP32 display in the cleanup or exit sections of the application.
• Modify the main rendering loop to use `esp32_render_frame` instead of ncurses functions when compiled for the ESP32. This can be done using preprocessor directives to conditionally compile the appropriate rendering code.

Create Makefile with contents:
• Modify the Makefile to add a new build target for the ESP32. This target should define the `ESP32` preprocessor flag and include paths for the ESP-IDF.
• Specify the compiler and linker flags necessary for ESP32 development, which may include specifying the hardware architecture and linking against ESP-IDF libraries.
• Include commands to compile `cmatrix_esp32.c` and link it with the rest of the application when building for the ESP32.
