DiSlord d2431f0cdc Increase screen render (in some cases up to 2x speedup), decrease stack usage (code size less on 1500 bytes) 
Write simple profiling definitions
 START_PROFILE
 STOP_PROFILE
Use it for detect sys tick amount and output to screen

main.c
 Reduce VNA_SHELL_MAX_LENGTH to 48, and made shell_line as static (reduce stack usage)
 Remove BaseSequentialStream *chp from command calls (use static shell_stream), it reduce code size and stack usage
 Use VNA_SHELL_FUNCTION definition for all commands
 Remove chMtxLock(&mutex);chMtxUnlock(&mutex); from commands, and define command flag for use it in calls
 Apply default scale from trace_info on trace change
 Led blink outside from main sweep cycle (better look, and less noise)
 Some size fixes

chprintf.c
 Implement small memory stream object, only put function and plot_printf(char *str, int size, const char *fmt, ...)
 Use it in all code (little increase speed, and huge decrease size)

 Restore USE_EXCEPTIONS_STACKSIZE = 0x180 (possible not need, but not good tested)

plot.c
 Made huge screen render profile (add some comments)
 Not use cell clipping on draw cell data (use constants increase speed, decrease stack usage (not need put it to stack))
 Clip cell if need only on screen flush
 Use new plot_printf, remove chsnprintf usage

Apply code style
============================================================================================================
Interesting fact
Usage memset(spi_buffer, DEFAULT_BG_COLOR, (h*CELLWIDTH)*sizeof(uint16_t)); dramatically decrease render speed
possibly it fill buffer by 8 bit data, so slow
Usage
  uint32_t *p = (uint32_t *)spi_buffer;
  while (count--) {
    p[0] = DEFAULT_BG_COLOR|(DEFAULT_BG_COLOR<<16);
    p[1] = DEFAULT_BG_COLOR|(DEFAULT_BG_COLOR<<16);
    p[2] = DEFAULT_BG_COLOR|(DEFAULT_BG_COLOR<<16);
    p[3] = DEFAULT_BG_COLOR|(DEFAULT_BG_COLOR<<16);
    p+=4;
  }
gives x10 speed perfomance

Draw polar and smit grid very slow (but i don`t know how increase it except use bitmaps, but it need about 5-8k flash size and file prepare)
On long lines render slow down, but clipping use more calculation, and not give good result
Need made stack usage check

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.
