## Hardware

Platform Nuclei: Find professional RISC-V Processor IP in Nuclei, first professional RISC-V IP company in Mainland China, match all your requirements in AIoT Era.

Microcontroller | HUMMINGBIRD
Frequency | 5MHz
Flash | 64KB
RAM | 64KB
Vendor | Nuclei

## Configuration

Please use `hbird_eval` ID for board option in “platformio.ini” (Project Configuration File):

    [env:hbird_eval]
    platform = nuclei
    board = hbird_eval

You can override default HummingBird Evaluation Kit settings per build environment using `board_***` option, where `***` is a JSON object path from board manifest hbird_eval.json. For example, `board_build.mcu`, `board_build.f_cpu`, etc.

    [env:hbird_eval]
    platform = nuclei
    board = hbird_eval

    ; change microcontroller
    board_build.mcu = HummingBird

    ; change MCU frequency
    board_build.f_cpu = 5000000L

## Debugging

PIO Unified Debugger - “1-click” solution for debugging with a zero configuration.

Warning

You will need to install debug tool drivers depending on your system. Please click on compatible debug tool below for the further instructions and configuration information.

You can switch between debugging Tools & Debug Probes using debug_tool option in “platformio.ini” (Project Configuration File).

HummingBird Evaluation Kit has on-board debug probe and IS READY for debugging. You don’t need to use/buy external debug probe.
