Doc written in timeout. Everything else in this file was done while
|
|
the timer was running.
|
|
|
|
I promised "Mark Kopecki" that writing the bin-to-intel-hex
|
|
converter would cost less than 15 minutes, and that it would be more
|
|
trouble to find a converter on the net than to write the converter
|
|
myself. I ended up spending over half an hour searching for
|
|
spec/converter/docs because of unreachable hosts on the internet. I
|
|
got a file with docs, after that it was 8 minutes.....
