# 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
|
|
|
|
Requires gcc-4.9 to build firmware from source code. (Not work gcc-5.4 or lator, because of SRAM shortage that those runtime use more SRAM)
|
|
|
|
### MacOSX
|
|
|
|
Install cross tools and firmware updating tool.
|
|
|
|
$ brew tap px4/px4
|
|
$ brew install gcc-arm-none-eabi-49
|
|
$ brew install dfu-util
|
|
|
|
Otherwise, use toolchains included inside LPCxpresso. Like this.
|
|
|
|
$ PATH=$PATH:/Applications/lpcxpresso_7.8.0_426/lpcxpresso/tools/bin
|
|
|
|
### Linux (ubuntu)
|
|
|
|
Download arm cross tools from [here](https://launchpad.net/gcc-arm-embedded/4.9/4.9-2015-q3-update).
|
|
This version is 32-bit binary, so additional lib32z1 and lib32ncurses5 package required.
|
|
|
|
$ wget https://launchpad.net/gcc-arm-embedded/4.9/4.9-2015-q3-update/+download/gcc-arm-none-eabi-4_9-2015q3-20150921-linux.tar.bz2
|
|
$ sudo tar xfj -C /usr/local gcc-arm-none-eabi-4_9-2015q3-20150921-linux.tar.bz2
|
|
$ PATH=/usr/local/gcc-arm-none-eabi-4_9-2015q3/bin:$PATH
|
|
$ sudo apt install -y lib32z1 lib32ncurses5
|
|
$ 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
|
|
|
|
If you can use docker, you can build firmware without installing arm toolchain.
|
|
|
|
$ cd NanoVNA
|
|
$ docker run -it --rm -v $(PWD):/work edy555/arm-embedded make
|
|
|
|
|
|
## Flash firmware
|
|
|
|
Boot MCU in DFU mode. To do this, jumper BOOT0 pin at powering device.
|
|
Then, burn firmware using dfu-util via USB.
|
|
|
|
$ dfu-util -d 0483:df11 -a 0 -s 0x08000000:leave -D build/ch.bin
|
|
|
|
|
|
## Control from PC
|
|
|
|
See [python directory](/python/README.md).
|
|
|
|
|
|
## Note
|
|
|
|
Hardware design material is disclosed to prevent bad quality clone. Please let me know if you would have your own unit.
