About:
Lpc21isp is a command-line utility that enables in-circuit programming (ISP) for NXP LPC2000 series microcontrollers via a serial interface. It allows developers to flash firmware, erase memory, and verify device contents directly on the target hardware. The tool serves as a crucial component in embedded development workflows for programming ARM-based microcontrollers.
Key Features:
  • Supports LPC2000 series microcontrollers via UART/serial interface
  • Enables flash programming, erasing, and verification operations
  • Command-line interface suitable for scripting and automation
  • Cross-platform compatibility (Linux, macOS, Windows)
Use Cases:
  • Flashing compiled firmware onto NXP LPC21xx microcontrollers during development
  • Automating firmware updates in production or testing environments via serial ISP
Alternatives:
  • J-Link – Commercial JTAG/SWD debugger with broader chip support but requires hardware purchase
  • OpenOCD – Open-source debugger with JTAG support, more complex setup but wider device compatibility
