A reusable JSON-RPC library for Arduino Serial communication. Memory limits, encoding overhead, and debugging requirements shape the protocol design. Encapsulating JSON-RPC logic in a library simplifies development and improves maintainability despite higher resource costs.

The EEPROM Programmer project uses Arduino MEGA or DUE to read from and write to EEPROM chips from the AT28Cxx family. A Python CLI provides erase, write, read, and verify operations. The series of posts below covers the full development process, from initial implementation to supported chip details.
