ESP32-C5 is a RISC-V based SoC with WiFi 6 (2.4GHz + 5GHz) support.
Treats C5 similarly to C3 for hardware capabilities (2 RMT channels,
no parallel I2S for LEDs, similar GPIO restrictions).
Changes across 25 files:
- Add CONFIG_IDF_TARGET_ESP32C5 conditionals alongside C3/C6 checks
- Add [esp32c5] and [env:esp32c5dev] build environments in platformio.ini
- Uses pioarduino platform (Tasmota framework lacks C5 Arduino libs)
- Exclude esp_dmx library (doesn't support C5 UART registers yet)
- Fix LEDC register access for IDF 5.5.0 (duty_init vs duty)
- Guard mbedtls_sha1_shim for IDF 5.5.0 (SHA1 built-in)
- Add C5 chip identification (ID: 0x0017) in OTA and web UI
Known limitations:
- RMT LED output shows flush timeouts (needs NeoPixelBus C5 support)
- WiFi AP confirmed working on hardware
- esp_dmx/DMX input disabled
- Experimental: requires pioarduino community platform
