Install: brew install lpc21isp

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
