Re: free logic analizer

Vincenzo, nice project! Some ideas: 1. you can use the DWT register (32bit counter) which increments in 13.88ns period on the Maple Mini - that could be your resolution then. It works on F407 but it is implemented on F103 as well, double check. UPDATE: It works on Maple Mini too.. Here is the code:...
