GCBASIC: AVR Series 1, DA and DB Support. Development report 1 

The video shows how you the first changes to the compiler to support the AVR Series 1, DA and DB microcontrollers.
The video shows how the legacy chips set the Pin Configuration and now the compiler, at this phase of development, can set the Direct Direct Pin Configuration for the Series 1, DA and DB microcontrollers.
The video also shows using ATMEL Studio 7 to debug the ASM to ensure the newly generated ASM works as expected.
Great progress.
Enjoy
