Yuri D'Elia 240f4c28ab Complete motion ramp checks 
- Add additional information in the output generated by rampgen in order
  to allow recalculating the acceleration curves independently
- Implement motion ramp checks inside test_motion_ramp.py

test_motion_ramp reads the output of a merged stepping sequence and
splits the motion of each axis, checking the acceleration curves
independently.

This ensures both that the acceleration curves are correct (as generated
by the PulseGen class) and that the multiplexed moves are too.

The nominal rate is checked exactly, while the acceleration/deceleration
segment allow for some deviation from an ideal curve.

This is currently 5% for both expected speed and acceleration, with
an absolute limit of 20mm/s of maximum difference in each point.

How to prepare build env and tools

As the first step extract the AVR-GCC to some dir, e.g. /home/user/AVRToolchainMMU/avr8-gnu-toolchain-5.4.0

Add /home/user/AVRToolchainMMU/avr8-gnu-toolchain-5.4.0/bin to your PATH.

mkdir .dependencies
cd .dependencies
mkdir gcc-avr-5.4.0
cd ..
utils/bootstrap.py

bootstrap.py will now download all the "missing" dependencies into the .dependencies folder:

  • clang-format-9.0.0-noext
  • cmake-3.15.5
  • ninja-1.9.0

Note: bootstrap.py will not try to download the AVR-GCC as there is already a directory called gcc-avr-5.4.0. This will be fixed when we find out where to download the correct packages reliably.

How to build the preliminary project so far:

Now the process is the same as in the Buddy Firmware:

utils/build.py

builds the firmware.hex in build/mmu_release

In case you'd like to build the project directly via cmake you can use an approach like this:

mkdir build
cd build
cmake .. -G Ninja -DCMAKE_TOOLCHAIN_FILE=../cmake/AnyAvrGcc.cmake
ninja

Should produce a firmware.hex file as well.
