NanoVNA - Very tiny handheld Vector Network Analyzer
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.
$ 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 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
