For quite a long time I’m thinking about simple code generating tools. I don’t want to use a special XML syntax or descriptive language but a simple Excel or OpenOffice sheet instead.<\/p>\n
The aim is to generated C source code for small microcontroller applications or retrocomputing systems.<\/p>\n
For the start I made a simple generator for finite state machines (Wikipedia entry<\/a>)<\/p>\n It is also my first script written in Python and thus not really as tidy and neat as I prefer. But it is working for now.<\/p>\n It takes the sheet from an OpenOffice .ods table like this:<\/p>\n
