Kwikstik UART

Question asked by dspNeil on Nov 1, 2011

I'm just getting started with my K40 Kwikstik in CW10.1, and do not have a tower system.  I've tried running several of the demos, and have been successful at building the MQX libraries to get the demos to debug and execute, however when I probe the UART5 TPs (which I believe are ttyf in software), I see no communication.  I have also tried switching the BSP_DEFAULT_IO_CHANNEL to "ttye:", which should be UART4 (the CAN TPs on the Kwikstik), and have probed these with a scope as well with no success.  What am I missing?  The demo I'm currently trying is the "io_kwikstikk40x256", and it builds successfully after enabling ttya and ttyb.

 

I also debugged to see that Hardware flow control is not being used, however I also can't figure out where this is set in the software.

 

Any help would be appreciated!

Thanks,

Neil
