Great effort @vbextreme, I'll test it as soon as I can. Is there any reason why it only works on 328 or is the code suitable for every 8bit AVR chip (like Mega2560 and 32u4)?

[vbextreme]

first I need board mega ad leonardo.
second need to study a mega && 32u4 datasheet.
and the last need to implement, is not very simple.
for now wait confirm is ok

togle one bug.

[vbextreme]

Togle error gcc for 22bit addressing and add some example

Please...this would be a great step forward

ported to the repository is not complete , I worked for a new version soon as I find some time I finish the job started .

The following scheduler allows me to compile multiple blink for leonardo but not for MEGA.
Does this help you?
