Hi
I regularly work with CW6.3 classic IDE and now I'm trying CW10 eclipse and have found that the following code works in CW10 slower than CW6.3.
I could not import the file classic project , so I made a new bareboard project and then copy the files.c on sources and files.h on Project_ Headers.
This way I could compile, install code on microcontroller, debug step by step and run without problem.
the only thing I've found is that when I work on CW10 The program runs slower
Working on CW6.3 function Delay_ms(1) generates a 1ms delay tested with osciloscope.
Working on CW10 function Delay_ms(1) generates a 1,7ms delay tested with osciloscope.
What will be the problem?
Best Regards
Eugenio
