feat(arch): implement SAUL-TEE ESP32 protocol specs from hal reference doc
Spec source: docs/SAUL-TEE-SYSTEM-REFERENCE.md (hal, 2026-04-04)
stm32_protocol.py — rewritten for inter-board UART protocol (ESP32 BALANCE ↔ IO):
- Frame: [0xAA][LEN][TYPE][PAYLOAD][CRC8] @ 460800 baud (was STX/ETX/CRC16)
- CRC-8 poly 0x07 over LEN+TYPE+PAYLOAD
- New message types: RC_CHANNELS(0x01), SENSORS(0x02), LED_CMD(0x10),
OUTPUT_CMD(0x11), MOTOR_CMD(0x12), HEARTBEAT(0x20)
mamba_protocol.py — updated CAN IDs and frame formats:
- Orin→BALANCE: DRIVE(0x300) f32×2 LE, MODE(0x301), ESTOP(0x302), LED(0x303)
- BALANCE→Orin: FC_STATUS(0x400) pitch/vbat/state, FC_VESC(0x401) rpm/current
- VESC node IDs: Left=56, Right=68 (authoritative per §8)
- VESC extended frames: STATUS1(cmd=9), STATUS4(cmd=16), STATUS5(cmd=27)
- Replaced old MAMBA_CMD_*/MAMBA_TELEM_* constants
can_bridge_node.py — updated to use new IDs:
- ORIN_CMD_DRIVE/MODE/ESTOP replace MAMBA_CMD_VELOCITY/MODE/ESTOP
- FC_STATUS handler: publishes pitch→/can/imu, vbat_mv→/can/battery
- FC_VESC handler: publishes rpm/cur→/can/vesc/left|right/state
- VESC STATUS1 extended frames decoded per node ID (56/68)
- Removed PID CAN command (not in new spec)
CLAUDE.md — updated with ESP32-S3 BALANCE/IO hardware summary + key protocols

feat: Add Issue #507 - Face display animations on STM32 LCD
Implements expressive face animations with 5 core emotions (happy/sad/curious/angry/sleeping) and smooth transitions on small LCD displays.
Features:
- State machine with smooth 0.5s emotion transitions (ease-in-out cubic easing)
- Automatic idle blinking (4-6s intervals, 100-150ms duration per blink)
- UART command interface via USART3 @ 115200 (text-based protocol)
- 30Hz target refresh rate via systick integration
- Low-level LCD abstraction supporting monochrome and RGB565
- Rendering primitives: pixel, line (Bresenham), circle (midpoint), filled rect
Architecture:
- face_lcd.h/c: Hardware-agnostic framebuffer & display driver
- face_animation.h/c: Emotion state machine & parameterized face rendering
- face_uart.h/c: UART command parser (HAPPY/SAD/CURIOUS/ANGRY/SLEEP/NEUTRAL/BLINK/STATUS)
- Unit tests (14 test cases): emotion transitions, blinking, rendering, all emotions
Integration:
- main.c: Added includes, initialization (servo_init), systick tick, main loop processing
- Pending: LCD hardware initialization (SPI/I2C config, display controller setup)
Files: 9 new (headers, source, tests, docs), 1 modified (main.c)
Lines: ~1450 total (345 headers, 650 source, 350 tests, 900 docs)
