Four functions: - Programming: can burn Flash ROM, EEPROM, etc. - Simulation: supports full-speed, single-step debugging and breakpoint debugging. - Simulation performance: uses USB interface for simulation debugging, one-step debugging and breakpoint debugging with fast response. - Programming performance: via USB interface, ICSP download, with download speed. Connectivity and compatibility: - Connects to PIC series microcontrollers via the ICSP interface, enabling seamless integration with Microchip’s official IDE MPLAB for easy development. - PC connection via USB: the PICkit3 development tool includes drivers for high-speed USB communication. - ICSP interface: the standard interface is specified by PICkit3 for connection to the target device. Firmware and device support: - Firmware upgradeable: Microchip plans to introduce additional PIC models and add new device models to the ICSP device support list in the future. What it is: - PICkit3 is a development tool that can simulate and download PIC online. It is an online simulation and download tool designed for beginners to learn, evaluate, and develop PIC series MCUs. Use scenarios: - Beginner learning PIC microcontrollers: connect to MPLAB, program firmware, and use debugging features to learn how code runs on a PIC. - Rapid prototyping and testing: simulate code flow, debug with breakpoints or single-step, then download via ICSP for real hardware testing. - Classroom or evaluation setup: an accessible tool to assess PIC series MCUs, evaluate firmware, and perform hands-on development.
