K10DN32M5 PTB17 otput problem!

ramazantoprak — Thu, 13 Jul 2017 11:13:55 GMT

Hi,

I am try to configure bsp of K10DN32M5, but when I choose PTB17 as a output pin it does not run, similarly when I want to choose this pin(32->PTB17) as UART0_TX , it does not run as well.

Do you have any ideas for this problem, problem is im my SW or HW or datasheet ?

Thank you for your help in advance.

Regards.

Hi Ramazan,

Would you please show me the full part number of K10? There is no PTB17 pin on MK10DN32VFM5.

You can refer below setps to toggle the output of PTB17.
1. Enable the clock gate of PORTB. ( SIM_SCGC5[PORTB]=1 )
2. PTB17 pin is default as TSI function, you should to select ALT1 mux as GPIO function. ( PORTB_PCR17[MUX] = 001)
3. Configure PTB17 Pin as general-purpose output. ( GPIOB_PDDR |= 0x20000 )
4. Toggle Output of PTB17 Pin. ( GPIOB_PTOR |= 0x20000 )

Best Regards,

Robin

When I look to the K10P48M50SF0RM referance manual, I can see PTB17 pin, and I already did what you said.

Best regards.
