Angus Gratton 861fbf6ab5 examples: Mark asm, pio, etc. as noqa: F821 (undefined-name). 
These files all use decorators (@asm_thumb, @asm_pio) that add names to the
function scope, that the linter cannot see.

It's useful to clear them in the file not in pyproject.toml as example code
will be copied and adapted elsewhere, and those developers may also use
Ruff (we hope!)

README.md

This is experimental, community-supported port for Cortex-M emulation as provided by QEMU (http://qemu.org).

The purposes of this port are to enable:

  1. Continuous integration
    • run tests against architecture-specific parts of code base
  2. Experimentation
    • simulation & prototyping of anything that has architecture-specific code
    • exploring instruction set in terms of optimising some part of MicroPython or a module
  3. Streamlined debugging
    • no need for JTAG or even an MCU chip itself
    • no need to use OpenOCD or anything else that might slow down the process in terms of plugging things together, pressing buttons, etc.

This port will only work with the [GNU ARM Embedded Toolchain]( https://developer.arm.com/downloads/-/arm-gnu-toolchain-downloads and not with CodeSourcery toolchain. You will need to modify LDFLAGS if you want to use CodeSourcery's version of arm-none-eabi. The difference is that CodeSourcery needs -T generic-m-hosted.ld while ARM's version requires --specs=nano.specs --specs=rdimon.specs to be passed to the linker.

To build and run image with builtin testsuite:

make -f Makefile.test test
