|
|
|

|
|
## 💾 Key Optimizations for ESP32-S3
|
|
|
|
### 1. **+200 KB RAM**
|
|
- 520 KB SRAM (vs 320 KB on base ESP32)
|
|
- Larger radio RX buffers → No packet loss on WiFi/SubGHz captures
|
|
- Bigger UI frame buffer → Smoother menu navigation
|
|
|
|
### 2. **Capacitive Touch (FT6336)**
|
|
- Built-in (original CYD uses resistive XPT2046)
|
|
- Better responsiveness, no calibration drift
|
|
- I2C-based (GPIO 4/5), no touch pressure variations
|
|
|
|
### 3. **Better SPI Timing**
|
|
- Can safely run 10 MHz (vs 8 MHz on ESP32)
|
|
- Faster radio module throughput
|
|
- Lower latency for interrupt-driven RX
|
|
|
|
### 4. **More GPIO (45 vs 34)**
|
|
- Cleaner radio control pins
|
|
- E07 PA module has dedicated TX_EN/RX_EN
|
|
- Expansion-ready for future modules
|
|
|
|
### 5. **USB OTG Native**
|
|
- No CH340 adapter needed (optional)
|
|
- Faster serial debug (480 Mbps USB 2.0)
|
|
- Can add USB-based radio modules
|
|
|

|
|
|
|
## 🔧 Architecture
|
|
|
|
### Core 0 (WiFi/Radio)
|
|
- WiFi AP/STA mode switching
|
|
- BLE advertiser + sniffer
|
|
- CC1101 receive interrupt handler
|
|
- NRF24 packet capture
|
|
- Dual-radio simultaneous operation (with Core 1 handling UI)
|
|
|
|
### Core 1 (UI/Touch)
|
|
- Display rendering (ILI9341 SPI)
|
|
- Touch polling + button handling (I2C FT6336)
|
|
- Menu navigation
|
|
- SPIFFS file browser (loot, .sub files, captures)
|
|
|
|
### Shared
|
|
- SPI bus (GPIO 11/12/13) with mutex arbitration
|
|
- SRAM heap (520 KB total, intelligently partitioned)
|
|
- FLASH (16 MB) — OTA-ready with dual app slots
|

## 🎮 Usage Example: WiFi Scanner
|
|
|
|
```cpp
|
|
// In src/main.cpp
|
|
#include <WiFi.h>
|
|
|
|
void scanWiFi() {
|
|
WiFi.mode(WIFI_STA);
|
|
WiFi.disconnect(true); // Turn off AP
|
|
delay(100);
|
|
|
|
int n = WiFi.scanNetworks();
|
|
for (int i = 0; i < n; i++) {
|
|
Serial.printf("%d. %s (%d dBm) [%s]\n",
|
|
i+1,
|
|
WiFi.SSID(i).c_str(),
|
|
WiFi.RSSI(i),
|
|
WiFi.isHidden(i) ? "HIDDEN" : "OPEN"
|
|
);
|
|
}
|
|
}
|
|
```

## 📝 Building Attack Modules
|
|
|
|
Template provides foundation. To add modules:
|
|
|
|
### Step 1: Create Driver
|
|
```cpp
|
|
// include/my_attack.h
|
|
class MyAttack {
|
|
public:
|
|
static void init();
|
|
static void execute();
|
|
static void stop();
|
|
};
|
|
```
|
|
|
|
### Step 2: Implement Logic
|
|
```cpp
|
|
// Use RadioCC1101, RadioNRF24, etc. already initialized
|
|
RadioCC1101::setFreq(433.92f);
|
|
RadioCC1101::transmit(payload, len);
|
|
```
|
|
|
|
### Step 3: Hook to UI
|
|
```cpp
|
|
// In src/main.cpp handleTouch()
|
|
if (buttonPressed("My Attack")) {
|
|
MyAttack::init();
|
|
MyAttack::execute();
|
|
}
|
|
```
|
|

## 🐛 Troubleshooting
|
|
|
|
| Issue | Solution |
|
|
|-------|----------|
|
|
| Board not detected | `pio device list` — check USB cable |
|
|
| Touch unresponsive | Verify I2C wiring (GPIO 4/5), try `TouchFT6336::calibrate()` |
|
|
| Radio not detected | Check GPIO in board_config.h, verify SPI clock |
|
|
| Heap exhausted | Enable heap trace, check for malloc/free leaks |
|
|
| UI laggy | Reduce SPI frequency or increase frame buffer size |
|
|
|
