This project aim to provide useful measuring tool for RF enthusiast. This repository contains source of NanoVNA firmware. ## Prepare ARM Cross Tools Install cross tools and dfu-util. $ brew tap PX4/px4 $ brew install gcc-arm-none-eabi $ brew instal dfu-util Otherwise, using toolchains inside LPCxpresso. Like this. $ PATH=$PATH:/Applications/lpcxpresso_7.8.0_426/lpcxpresso/tools/bin ## Building firmware Fetch ChibiOS submodule into tree. $ cd nanovna $ git submodule update --init --recursive Enter firmware directory and make it. $ make ## Burn it Boot MCU in DFU mode. To do this, jumper BOOT0 pin at powering on. And then, burn firmware using dfu-util via USB. $ dfu-util -d 0483:df11 -a 0 -s 0x08000000:leave -D build/ch.bin # Control NanoVNA from Host PC NanoVNA is able to work standalone, but also be controlled from host PC.
