UART2 on PTE22 & PTE23

[ralphs]

Hi,

I'm using the freedom board with the Mbed compiler and am having trouble accessing UART2 on PTE22 & PTE23. I'm wondering if this is a problem with the compiler or something to do with the board?

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.

Thank, Ralph

Hi,

Have you tried with CodeWarrior MCU V10.x software or IAR ARM Workbench?

You could use above IDE softwares to control FRDM-KL25Z UART2 pins.

Before operation PTE22 and PTE23 pins, it need to enable PORTE clock gate at SIM_SCGC5 register at first.

Wish it helps.

Hi Hui_ma,

Thanks for your comments. I haven't tried any other compilers, but I will.

Cheers, Ralph
