I just wanted to say thank you. I have been having the same problem.
This is my third project with the ooPic and never had this problem.
But, all my other projects required me to program the ooPic and then
plug it into the project for testing so I had to remove the
programming cable each time. This time I set up a test bench and I
haven't been removing my programming cable and nothing was working.
Thanks to your post I was able to locate the issue and reproduce it
at will. Thank you and yes I am already looking at getting the
serial cable.
Have a great day.
