yeap,
TICK_COUNT appControl(LOOP_COUNT loopCount, TICK_COUNT loopStart)
is your main.
You can only have one .c file with WebbotLib. Use .h files if you need more files.
I feel like webbot hides to much from the user? like if you really want to learn programming i dont think is a good idea
It really depends on what your goals are. Some people just want to make a neat robot and focus on high level stuff like line following - they don't want to read the 600 page Atmel datasheet to figure out which bits to flip, how to interface I2C, or have to know what a prescale value is.
If your goal was to learn the low-level details, you don't want to use a library. Just a text editor and a compiler would be fine.
But in the end, you only have 24 hours in a day, so more time focused on learning low-level stuff means less time spent learning high-level stuff.
