Hi,
I'm using the FRDM-KL25Z board with the Mbed compiler and am having trouble accessing the UART's. Obviously UART0 is unavailable if the SDA connector is in use. But I'm also unable to access UART1 on PTE0,1 & UART2 on PTE22 & PTE23. I'm wondering if this is a problem with the compiler or something to do with the board? Is Port E simply unavailable?
Also, can UART0 be used if I'm not using SDA? ie will there be a contention if I wire the PTA0,1 pins off the board to external devices?
It's not a show-stopper if I can't use the port but it would make the design a bit simpler. Any advice appreciated.
Thanks, Ralph
