Hey :-) Just wanted to let you know that I want to use the CC2650 for my BA-thesis and have hardware on the way. -> nice to know somebody is also interested in having a port
The boards should arrive during the course of next week and I will have a quick look. I probably wont start porting until christmas, though. But who knows? kind regards Leon On 14/11/15 15:33, Adam Hunt wrote: > Has anyone taken a look at TI's CC2560 or C1310 processors?
