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.
UPDATE: Recent gcc version works to build NanoVNA, no need old version.
Install cross tools and firmware updating tool.
$ brew tap px4/px4
$ brew install gcc-arm-none-eabi-80
$ brew install dfu-util
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 -C /usr/local gcc-arm-none-eabi-8-2018-q4-major-linux.tar.bz2
$ PATH=/usr/local/gcc-arm-none-eabi-8-2018-q4-major/bin:$PATH
$ sudo apt install -y dfu-util
Fetch source and submodule.
$ git clone https://github.com/ttrftech/NanoVNA.git
$ cd NanoVNA
$ git submodule update --init --recursive
Just make in the directory.
$ make
Using this docker image without installing arm toolchain.
$ cd NanoVNA
$ docker run -it --rm -v $(PWD):/work edy555/arm-embedded:8.2 make
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
