I am using a very basic sketch, wich makes two LEDs blink (one on the
MCU board) and one on my base board). This is just in case the LED
on the CPU board does not work ...
The MCU boards I am using, I bought online:

I have made a base board where they plug it in. But I can operate them
outside my base board or plugged in, it doesn't matter. Results are the same.
I have been thinking about HSE, and did add a "USE_HSI" ifdef block
in your libraries, Roger. Now am trying to find the correct place in Koduino.
I did a physical inspection and did not see anything wrong, like solder
I have one question about the vector tables. I noticed that the vector table
might have something like this:
0800 1ffd, Reset Vector
0800 0d1d, NMI Vector
In both cases it's an odd address, bit 0 is set (this actually applies to all
But the actual locations are:
What is going on here ? It's like actual address + 1 ?! This does work on 6 of
my boards, so it must be correct !
But I still would like to understand it. I have been searching through the almost
2000 pages of the programming manual, and nothing so far ...
Many thanks !!!
