tinyNim

Nim on STM32F446 uisng nimble for building

Dependencies

• nim-configparser nimble install configparser
• arm-none-eabi-gcc compiler
• st-link utility (unix/linux == texane/stlink)

Howto

Copy the two following folders to your ".nimble/pkgs/" directory:

• tinyNim-0.1.0
• tinyNimBoards-0.1.0

Open the tinyNimProject in vSCode or other editor.

In the tinyNim.nimble script, make sure that the following section regarding nimbase.h fits your environment:

# makeNim #####################################################################
task makeNim, "Compile Nim files to C":
  echo("Compiling Nim files")
  if not system.dirExists("./nimcache"):
    mkDir("./nimcache")
  cpFile("c:/nim/lib/nimbase.h", "./nimcache/nimbase.h")
  exec "nim $# $#" % [nimflags, nimMain]

If on Linux/Unix make sure to remove .exe from arm-none-eabi-objcopy and arm-none-eabi-gcc in the nimble script

Building the project

You need to have arm-none-eabi-gcc installed and on your PATH. The nimble script defines four tasks:

• nimble make # Compiles both nim and .c files
• nimble makeNim # Compiles only the nim files
• nimble makeC # Compiles all the .c files
• nimble flash # Uploads the compilede binary to the board.
