DiSlord 23c765b719 Fix very strange bug, on band 2 
!!!!! Don`t understand why si5351 non stable on band 2 then change from band 3
It fixed if set before sweep one frequency from band 1 (for example 50MHz)
Possibly problem in tlv320aic3204_set_gain, call only si5351_set_frequency_with_offset not work

Little faster call command from shell

Fix interpolation if points < POINTS_COUNT

NanoVNA - Very tiny handheld Vector Network Analyzer

GitHub release CircleCI

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

Companion Tools

There are seveal numbers of great companion PC tools from third-party.
