||||
# - PSRAM erkannt
|
||||
# - Display initialisiert
|
||||
# - Keine Errors
|
||||
```
|
||||
|
||||
### Mit ROM testen:
|
||||
|
||||
```bash
|
||||
# 1. ROM auf SD-Karte: /roms/gb/tetris.gb
|
||||
# 2. SD-Karte einlegen
|
||||
# 3. Neustarten
|
||||
# 4. ROM sollte laden
|
||||
```
|

|
||||
## 💡 Tipps
|
||||
|
||||
### Schneller entwickeln:
|
||||
|
||||
```bash
|
||||
# Nur App flashen (schneller):
|
||||
idf.py app-flash
|
||||
|
||||
# Monitor ohne Flash:
|
||||
idf.py monitor
|
||||
|
||||
# Build + Flash + Monitor in einem:
|
||||
idf.py build flash monitor
|
||||
```
|
||||
|
||||
### Debug aktivieren:
|
||||
|
||||
```bash
|
||||
idf.py menuconfig
|
||||
|

2. **Tag scannen** → ROM startet automatisch!
|
||||
3. **Mapping-File:** `/sd/nfc_roms.json`
|
||||
|
||||
Beispiel `nfc_roms.json`:
|
||||
```json
|
||||
{
|
||||
"mappings": [
|
||||
{
|
||||
"tag_uid": "04:12:34:56:78:9A:B0",
|
||||
"rom_path": "/roms/gb/tetris.gb"
|
||||
},
|
||||
{
|
||||
"tag_uid": "04:AB:CD:EF:12:34:56",
|
||||
"rom_path": "/roms/gb/pokemon_red.gb"
|
||||
}
|
||||
]
|
||||
}
|
||||
```
|
||||
|
||||
### Link Cable 2-Player
|
||||
|
||||
1. **Zwei GameBoys bauen**

||||
- SCLK ↔ SCLK
|
||||
- SOUT ↔ SIN (gekreuzt!)
|
||||
- SIN ↔ SOUT (gekreuzt!)
|
||||
- GND ↔ GND
|
||||
3. **Gleiches ROM laden** auf beiden
|
||||
4. **Im Spiel:** 2-Player Mode wählen
|
||||
5. **Spielen!** 🎮🔗🎮
|
||||
|
||||

|
||||
## GNUBoy Core Integration
|
||||
|
||||
Der originale GNUBoy Core ist **zu umfangreich** um ihn hier komplett einzufügen (~50.000 Zeilen C-Code).
|
||||
|
||||
Stattdessen zeige ich dir **GENAU** wie du ihn integrierst!
|
||||
|
||||
---
|
||||
|
||||
## 📦 Schritt 1: GNUBoy Quellcode holen
|
||||
|
||||
### Option A: Von esplay-gb (Empfohlen!)
|
||||
|
||||
```bash
|
||||
# Klone esplay-gb
|
||||
cd /tmp
|
||||
git clone https://github.com/pebri86/esplay-gb.git
|
||||
|
||||
# Kopiere GNUBoy Core files
|
||||
cd esp32-s3-gnuboy/components/gnuboy/
|
||||
|
||||
# Kopiere alle .c und .h Dateien:
|
||||
cp /tmp/esplay-gb/components/gnuboy-go/*.c .
|
||||
cp /tmp/esplay-gb/components/gnuboy-go/*.h include/
|
||||
```
|
||||
|
||||
### Option B: Original GNUBoy
|
||||
|
||||
```bash
|
||||
# Original GNUBoy (muss angepasst werden!)
|
||||
git clone https://github.com/rofl0r/gnuboy.git
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## 📝 Schritt 2: CMakeLists.txt anpassen
|
||||
|
||||
Ersetze `components/gnuboy/CMakeLists.txt`:

|
||||
|
||||
## 🔧 Schritt 3: ESP32-Spezifische Anpassungen
|
||||
|
||||
### 3.1 Display Interface (`esp32_lcd.c`)
|
||||
|
||||
```c
|
||||
#include "st7789.h"
|
||||
#include "defs.h"
|
||||
#include "regs.h"
|
||||
#include "lcd.h"
|
||||
#include "fb.h"
|
||||
|
||||
// GameBoy display ist 160x144
|
||||
// ST7789 ist 240x320
|
||||
// → Zentrieren oder skalieren!
|
||||
|
||||
#define GB_WIDTH 160
|
||||
#define GB_HEIGHT 144
|
||||
|
||||
// Framebuffer (RGB565)
|
||||
static uint16_t framebuffer[GB_WIDTH * GB_HEIGHT];
|
||||
|
||||
void lcd_begin(void)
|
||||
{
|
||||
// Called at start of LCD frame
|
||||
memset(framebuffer, 0, sizeof(framebuffer));
|
||||
}
|
||||
|
||||
void lcd_refreshline(void)
|
||||
{
|
||||
// Called for each scanline (144 times per frame)
|
||||
// GNUBoy's fb structure hat die aktuellen Pixel
|
||||
|
||||
byte *src = fb.ptr; // GNUBoy framebuffer pointer
|
||||
int line = R_LY; // Current scanline (0-143)
|
||||
|
||||
// Convert GameBoy pixels to RGB565
|
||||
for (int x = 0; x < GB_WIDTH; x++) {
|
||||
byte pixel = src[x]; // 0-3 (GameBoy 4 Farben)
|
||||
|
||||
// Convert to RGB565 (Grayscale)
|
||||
uint16_t color;
|
||||
switch (pixel) {
|
||||
case 0: color = 0xFFFF; break; // White
|
||||
case 1: color = 0xAD55; break; // Light gray
|
||||
case 2: color = 0x52AA; break; // Dark gray
|
||||
case 3: color = 0x0000; break; // Black
|
||||
}
|
||||
|
||||
framebuffer[line * GB_WIDTH + x] = color;
|
||||
}
|
||||
}
|
||||
|
||||
void lcd_end(void)
|
||||
{
|
||||
// Frame complete - send to display!
|
||||
|
||||
// Center on 240x320 display
|
||||
int x_offset = (240 - GB_WIDTH) / 2; // 40 pixels
|
||||
int y_offset = (320 - GB_HEIGHT) / 2; // 88 pixels
|
||||
|
||||
st7789_draw_buffer(framebuffer, x_offset, y_offset,
|
||||
GB_WIDTH, GB_HEIGHT);
|
||||
}
|
||||
```
|
||||
|
||||
### 3.2 Audio Interface (`esp32_sound.c`)
|
||||
|
||||
```c
|
||||
#include "driver/i2s.h"
|
||||
#include "pcm.h"
|
||||
|
||||
// I2S DMA buffer
|
||||
#define DMA_BUF_COUNT 8
|
||||
#define DMA_BUF_LEN 512
|
||||
|
||||
void pcm_init(void)
|
||||
{
|
||||
i2s_config_t i2s_config = {
|
||||
.mode = I2S_MODE_MASTER | I2S_MODE_TX,
|
||||
.sample_rate = 32000, // GameBoy: 32kHz
|
||||
.bits_per_sample = I2S_BITS_PER_SAMPLE_16BIT,
|
||||
.channel_format = I2S_CHANNEL_FMT_RIGHT_LEFT,
|
||||
.communication_format = I2S_COMM_FORMAT_I2S,
|
||||
.dma_buf_count = DMA_BUF_COUNT,
|
||||
.dma_buf_len = DMA_BUF_LEN,
|
||||
};
|
||||
|
||||
i2s_pin_config_t pin_config = {
|
||||
.bck_io_num = I2S_PIN_BCLK,
|
||||
.ws_io_num = I2S_PIN_LRC,
|
||||
.data_out_num = I2S_PIN_DIN,
|
||||
.data_in_num = -1
|
||||
};
|
||||
|
||||
i2s_driver_install(I2S_NUM, &i2s_config, 0, NULL);
|
||||
i2s_set_pin(I2S_NUM, &pin_config);
|
||||
}
|
||||
|
||||
int pcm_submit(void)
|
||||
{
|
||||
// Send audio samples to I2S
|
||||
size_t bytes_written;
|
||||
i2s_write(I2S_NUM, pcm.buf, pcm.len * 2, &bytes_written, 0);
|
||||
return 0;
|
||||
}
|
||||
```
|
||||
|
||||
### 3.3 Input Interface (`esp32_input.c`)
|
||||
|
||||
```c
|
||||
#include "driver/gpio.h"
|
||||
#include "rc.h"
|
||||
#include "hardware_config.h"
|
||||
|
||||
// Button state
|
||||
static int pad_state = 0;
|
||||
|
||||
// GameBoy button bits
|
||||
#define PAD_RIGHT 0x01
|
||||
#define PAD_LEFT 0x02
|
||||
#define PAD_UP 0x04
|
||||
#define PAD_DOWN 0x08
|
||||
#define PAD_A 0x10
|
||||
#define PAD_B 0x20
|
||||
#define PAD_SELECT 0x40
|
||||
#define PAD_START 0x80
|
||||
|
||||
void ev_poll(void)
|
||||
{
|
||||
// Read GPIO buttons
|
||||
pad_state = 0;
|
||||
|
||||
if (!gpio_get_level(BTN_RIGHT)) pad_state |= PAD_RIGHT;
|
||||
if (!gpio_get_level(BTN_LEFT)) pad_state |= PAD_LEFT;
|
||||
if (!gpio_get_level(BTN_UP)) pad_state |= PAD_UP;
|
||||
if (!gpio_get_level(BTN_DOWN)) pad_state |= PAD_DOWN;
|
||||
if (!gpio_get_level(BTN_A)) pad_state |= PAD_A;
|
||||
if (!gpio_get_level(BTN_B)) pad_state |= PAD_B;
|
||||
if (!gpio_get_level(BTN_SELECT)) pad_state |= PAD_SELECT;
|
||||
if (!gpio_get_level(BTN_START)) pad_state |= PAD_START;
|
||||
|
||||
// Update GNUBoy's pad structure
|
||||
pad_set(PAD_RIGHT, (pad_state & PAD_RIGHT) ? 1 : 0);
|
||||
pad_set(PAD_LEFT, (pad_state & PAD_LEFT) ? 1 : 0);
|
||||
pad_set(PAD_UP, (pad_state & PAD_UP) ? 1 : 0);
|
||||
pad_set(PAD_DOWN, (pad_state & PAD_DOWN) ? 1 : 0);
|
||||
pad_set(PAD_A, (pad_state & PAD_A) ? 1 : 0);
|
||||
pad_set(PAD_B, (pad_state & PAD_B) ? 1 : 0);
|
||||
pad_set(PAD_SELECT, (pad_state & PAD_SELECT) ? 1 : 0);
|
||||
pad_set(PAD_START, (pad_state & PAD_START) ? 1 : 0);
|
||||
}
|
||||
```
|
||||
|
||||
### 3.4 Link Cable Interface
|
||||
|
||||
In `hw.c` von GNUBoy, ersetze die Serial-Transfer Funktion:
|
||||
|
||||
```c
|
||||
#include "link_cable.h"
|
||||
|
||||
void hw_serial_transfer(byte value)
|
||||
{
|
||||
// Original GNUBoy Code:
|
||||
// R_SB = value;
|
||||
// ... timing ...
|
||||
// R_SB = 0xFF;
|
||||
|
||||
// NEU: Mit Link Cable!
|
||||
if (link_cable_is_connected()) {
|
||||
byte received = link_cable_transfer_byte(value);
|
||||
R_SB = received;
|
||||
} else {
|
||||
R_SB = 0xFF; // No connection
|
||||
}
|
||||
|
||||
// Trigger serial interrupt
|
||||
hw_interrupt(IF_SERIAL, IF_SERIAL);
|
||||
}
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## 🎮 Schritt 4: Main.c erweitern
|
||||
|
||||
```c
|
||||
#include "gnuboy.h"
|
||||
#include "loader.h"
|
||||
#include "emu.h"
|
||||
|
||||
void app_main(void)
|
||||
{
|
||||
// ... init hardware ...
|
||||
|
||||
// Initialize GNUBoy
|
||||
emu_reset();
|
||||
|
||||
// Load ROM (from SD or NFC)
|
||||
char rom_path[64];
|
||||
|
||||
// Try NFC first
|
||||
if (nfc_manager_get_rom(rom_path, sizeof(rom_path)) == ESP_OK) {
|
||||
ESP_LOGI(TAG, "Loading ROM from NFC: %s", rom_path);
|
||||
} else {
|
||||
// Default ROM
|
||||
strcpy(rom_path, "/sdcard/roms/tetris.gb");
|
||||
}
|
||||
|
||||
// Load ROM file
|
||||
if (rom_load(rom_path) != 0) {
|
||||
ESP_LOGE(TAG, "Failed to load ROM!");
|
||||
return;
|
||||
}
|
||||
|
||||
ESP_LOGI(TAG, "ROM loaded, starting emulation...");
|
||||
|
||||
// Main emulation loop
|
||||
while (1) {
|
||||
emu_run(); // Run one frame (60 FPS)
|
||||
vTaskDelay(pdMS_TO_TICKS(16)); // ~60 Hz
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
---
|
||||
|
||||

|
||||
|
||||
## 💡 Tipps
|
||||
|
||||
**Build-Fehler?**
|
||||
- Fehlende Header? → Include-Pfade prüfen
|
||||
- Linker-Fehler? → CMakeLists.txt prüfen
|
||||
|
||||
**Läuft langsam?**
|
||||
- Compiler-Optimierung: `-O3` in CMakeLists
|
||||
- PSRAM nutzen für Framebuffer
|
||||
- DMA für Display-Transfer
|
||||
|
||||
**Kein Bild?**
|
||||
- LCD-Refresh Funktion prüfen
|
||||
- Farb-Konvertierung OK?
|
||||
- Framebuffer-Größe?
|
||||
|
||||
**Kein Sound?**
|
||||
- I2S Sample Rate (32kHz)
|
||||
- DMA Buffer-Größe
|
||||
- Lautstärke-Poti?
|
||||
|
||||
