LPC1768 UART Firmware Replication

I need1. Firmware Development Develop firmware in C (CMSIS/Keil uVision 5) for NXP LPC1768 ARM Cortex-M3 MCU. Configure and integrate 3 UART channels: * Develop interrupt-driven UART communication (TX/RX), using ring buffer / circular buffer. Replicate functionality of the existing working HEX file on the provided hardware and deliver complete, maintainable source code. 2. Protocol Integration * Implement custom communication protocol compatible with existing application (framing, synchronization, packet validation). * Support for command-response sequences and handling of variable-length message bytes. * Ensure full functional equivalence with the reference HEX firmware. 3. Testing & Validation * Develop test firmware for loopback and communication validation of RS232/RS485. * Debug and validate communication using oscilloscope/logic analyzer. * Integration testing with custom harness hardware and host PC application.
