To generate optimal code, size itself needs to be of the same type as the index to avoid promotion to the largest type. In full(), wrap the subtraction explicity in another type cast to avoid another automatic type promotion. |

Prusa-Firmware-MMU-Private
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.
