RS485 Enabled Industrial Keypad Integration

Scope of Work
1. Code Setup & Verification
• Ensure proper compilation and flashing on STM32 Nucleo board at my end and in my system.
• Verify no missing dependencies or configuration issues
2. Hardware Testing Support
• Assist in testing keypad inputs.
• Validate LED indications
• Ensure debounce and response reliability
3. Communication Testing
RS485:
• Verify communication over RS485 (send/receive data)
• Ensure proper protocol handling (Modbus and custom protocol)
• Debug any transmission / reception errors
TCP/IP:
• Verify Ethernet communication
• Test data exchange over network (PC / PLC)
• Ensure stable connection and correct packet handling
4. Debugging & Fixes
• Fix any bugs found during testing
• Optimize performance if required
Deliverables
• Fully working and tested code (RS485 + TCP/IP)
