Hi All, Understood about the future modes, I was hoping to support 700D (when released) so perhaps switching processor is desirable. My skillset is 90%/10% hardware/software so both a complete rewrite and porting to a totally different platform are out for me. I might take a look at other ST options, several of you have mentioned the F7 and a quick look seems promising. Does anyone with more experience have a specific part number to recommend?
Low cost, whilst nice, isn't really a goal for me, but physical size and power consumption are.
