uP7 logging library demo on STM32 USB-CDC device

Inspired by the article on Habr.

Software required:

• STM32 Cube MX
• Cmake 3.8+
• ARM GCC compiler
• GCC compiler for Linux, or Visual Studio 16 2019 for Windows
• mingw32-makefile (only for Windows)
• Baical server executable
• uP7 library archive

Hardware required:

• WeAct STM32F411 MiniF4 ("blackpill")

Project structure

.
|-- up7_client : STM32 USB-CDC device with uP7 library integrated
|   |-- Core, Drivers, Middlewares, USB_DEVICE : directories generated by STM32Cube
|   |-- startup_stm32f411xe.s, STM32F411CEUx_FLASH.ld : toolchain files generated by STM32Cube
|   |-- Makefile, up7_client.ioc, .mxproject : project files generated by STM32Cube
|   |-- CMakeLists.txt, gcc_cm4f.cmake, stm32cube.cmake : custom CMake scripts to wrap over STM32Cube project
|   |-- App : directory with source files of the demo application
|   `-- up7 : uP7lib files
|       |-- lib : library sources
|       `-- preproc : directory for the preprocessor output (originally contains an .xml file only)
`-- up7_utils : Utilities to make demo work
    |-- P7lib, uP7lib, uP7proxyLib : libraries from the original uP7 archive
    |-- uP7preProcessor : preprocessor tool to generate some headers and meta information for server
    `-- up7_serial_proxy : custom proxy server to make a bridge between USB-CDC serial port and Baical UDP port

Build

• Build utilities first:

  cd up7_utils
  ./cmake_build.sh

• Then build STM32 client:

  cd up7_client
  ./cmake_build.sh

• Flash STM32 firmware in the way you like (via bootloader, Openocd, ST-Link utility or similar).

• Run Baical server executable

• Run proxy server (run executable without arguments to see the help):

  cd up7_utils/build/up7_serial_proxy
  ./up7_serial_proxy ../../../up7_client/up7/preproc /dev/ttyACM0 115200 1000 127.0.0.1 9009

• If all is good you will see online client in the Baical main window
