# About

NanoVNA is very tiny handheld Vector Network Analyzer (VNA). It is

standalone with lcd display, portable device with battery. This

project aim to provide an RF gadget but useful instrument for

enthusiast.

This repository contains source of NanoVNA firmware.

## Prepare ARM Cross Tools

**UPDATE**: Recent gcc version works to build NanoVNA, no need old version.

### MacOSX

Install cross tools and firmware updating tool.

    $ brew tap px4/px4

    $ brew install gcc-arm-none-eabi-80

    $ brew install dfu-util

### Linux (ubuntu)

Download arm cross tools from [here](https://developer.arm.com/tools-and-software/open-source-software/developer-tools/gnu-toolchain/gnu-rm/downloads).

    $ wget https://developer.arm.com/-/media/Files/downloads/gnu-rm/8-2018q4/gcc-arm-none-eabi-8-2018-q4-major-linux.tar.bz2

    $ sudo tar xfj gcc-arm-none-eabi-8-2018-q4-major-linux.tar.bz2 -C /usr/local

    $ PATH=/usr/local/gcc-arm-none-eabi-8-2018-q4-major/bin:$PATH

    $ sudo apt install -y dfu-util

## Fetch source code

Fetch source and submodule.

    $ git clone https://github.com/ttrftech/NanoVNA.git

    $ cd NanoVNA

    $ git submodule update --init --recursive

## Build

Just make in the directory.

    $ make

### Build firmware using docker

Using [this docker image](https://hub.docker.com/r/edy555/arm-embedded) and without installing arm toolchain, you can build the firmware.

    $ cd NanoVNA

    $ docker run -it --rm -v $(PWD):/work edy555/arm-embedded:8.2 make

## Flash firmware

First, make device enter DFU mode by one of following methods.

* Jumper BOOT0 pin at powering device

* Select menu Config->DFU (needs recent firmware)

Then, flash firmware using dfu-util via USB.

    $ dfu-util -d 0483:df11 -a 0 -s 0x08000000:leave -D build/ch.bin

Or simply use make.

    $ make flash
