Yuri D'Elia ea3b8e5c85 pulse_gen: Fix acceleration_rate block calculations 
The acceleration_rate should really by a premultiplication by 1<<24 so
that the division in Step() (while calculating the acc_step_rate) can be
computed again with a right shift.

This was incorrectly changed to F_CPU, which was close enough but would
cause the acceleration to be always slighly slower than expected.

Fix the ratio, but keep the multiplication in fixed-point to avoid a
float conversion.

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.
