PSRAM (Optional) + +FREENOVE S3 does NOT include PSRAM. If you add it later: +``` +Board: esp32-s3-devkitc-1-n16r8 +build_flags = -DBOARD_HAS_PSRAM=1 +``` + +This gives unlimited heap for large captures. + +--- + +## Troubleshooting + +### Touch Not Working + +1. Check I2C address: `0x38` (hard-coded in driver) +2. Verify wiring: GPIO 4 (SDA), GPIO 5 (SCL) +3. Try `TouchFT6336::calibrate()` in setup +4. Serial debug: Enable `LOG_LOCAL_LEVEL=ESP_LOG_DEBUG` in platformio.ini + +### Radio Module Not Detected + +1. Check GPIO assignments in `board_config.h` +2. Verify SPI bus (GPIO 11/12/13 shared) +3. Look for brownout resets → need external 3.3V buck for PA modules +4. Test with `Tools > Radio Test` module once UI is complete + +### Heap Fragmentation + +If you see "heap memory exhausted" after ~1 hour: + +1. Enable psram logging: `heap_trace_start(HEAP_TRACE_ALL)` +2. Find leaks: Check WiFi/BLE event callbacks +3.

FLASH-Based Lookup Tables + +Instead of computing in RAM: +```cpp +// ❌ Slow: Calculate on each TX +for (int i = 0; i < 32; i++) { + ccitt_crc16(data[i]); // ~2ms per byte +} + +// ✅ Fast: Pre-computed CRC table +const uint16_t crc_table[256] PROGMEM = { ... }; +uint16_t crc = crc_table[data[0]]; // O(1), 10µs +``` + +**Savings:** 64 KB FLASH for pre-computed tables → 100x speed improvement on checksums. + +### 3. Packet Buffer Pooling + +```cpp +// ❌ Inefficient: Allocate/free per packet +void handlePacket() { + uint8_t* pkt = malloc(256); + process(pkt); + free(pkt); // Heap fragmentation! +} + +// ✅ Efficient: Pre-allocated ring buffer +uint8_t pkt_pool[16][256]; // 4 KB fixed +uint8_t pkt_idx = 0; +void handlePacket() { + process(pkt_pool[pkt_idx++ % 16]); // No malloc/free +} +``` + +**Benefit:** Zero fragmentation, predictable timing. + +### 4. SPI Bus Arbitration + +```cpp +// Multiple radios share SPI (GPIO 11/12/13) +// Must avoid simultaneous access + +class SPIRadioManager { + static SemaphoreHandle_t spi_mutex; + + static void acquire() { + xSemaphoreTake(spi_mutex, portMAX_DELAY); + } + + static void release() { + xSemaphoreGive(spi_mutex); + } +}; + +// In each radio driver: +SPIRadioManager::acquire(); +SPI.transfer(cmd); +SPIRadioManager::release(); +``` + +**Latency:** <1ms for mutex contention (negligible). + +### 5. Interrupt-Driven RX + +```cpp +// ❌ Polling: Wastes CPU +void loop() { + if (digitalRead(CC1101_GDO0)) { + handleRx(); // 10ms response time + } +} + +// ✅ Interrupt: Event-driven +void setup() { +
