Sure debugging with GPIOs is nice for getting the timing right, but not to get internal states of your code. There are sophisticated debug tools for ARM, but unfortunately there's no free toolchain and cheap debugger that supports them. 

In my case the code breaks when the debugging introduces too big delays, but I can't just debug with 2 GPIOs. A trace tool would be the right choice.
