CCS/LAUNCHXL-CC1352P: Can not switch on the led.

Other Parts Discussed in Thread: CC1352P

Tool/software: Code Composer Studio

I began study the cc1352P and take lake base the BLE Project_Zero. I config the DIO17 and try to switch on the led. But the led don't switch on. In the IOC register and DOUT I can see value lake for DIO6 and DIO7 (led on the board) but when I connect my pin to led the led is not light.

The IOCFG 17 = 0x20106800

In my code i change

//Was!
PIN_Config ledPinTable[] = {
    Board_PIN_RLED | PIN_GPIO_OUTPUT_EN | PIN_GPIO_LOW | PIN_PUSHPULL |
    PIN_DRVSTR_MAX,
    Board_PIN_GLED | PIN_GPIO_OUTPUT_EN | PIN_GPIO_LOW | PIN_PUSHPULL |
    PIN_DRVSTR_MAX,
    PIN_TERMINATE
};

//NOW!
PIN_Config ledPinTable[] = {
    Board_PIN_RLED | PIN_GPIO_OUTPUT_EN | PIN_GPIO_LOW | PIN_PUSHPULL |
    PIN_DRVSTR_MAX,
    Board_PIN_GLED | PIN_GPIO_OUTPUT_EN | PIN_GPIO_LOW | PIN_PUSHPULL |
    PIN_DRVSTR_MAX,
    My_PIN_D17 | PIN_GPIO_OUTPUT_EN | PIN_GPIO_LOW | PIN_PUSHPULL |
    PIN_DRVSTR_MAX,
    PIN_TERMINATE
};

When I call  ledPinHandle = PIN_open(&ledPinState, ledPinTable);

and  after this     PIN_setOutputValue(ledPinHandle, My_PIN_D17,1); I saw change value in DUOT31_0

Your question is not clear. You write that you are trying to turn on the LED but the LEDs are, as you say, on DIO6 and DIO7. I assume that you use an external LED or a logic analyzer to monitor the pin.

You are not showing in your code how you define My_PIN_D17 to be mapped to IOID_17.

Yes My_PIN_D17 to be mapped to IOID_17.
And how i can wrote i can see right value in the right bit in the DOUT31_0
I connect the Board led to DIO_17 by the wire. (open jumper and connect wire)

P.S.

Now I change to pin 11 and it is work... What can it be?? My be JTAG?? And how can I use pin 16, 17?

DIO 16 and 17 are also jtag TDO and TDI pins so make sure the jumpers of TDO and TDI between XDS110 and CC1352P are removed.

Yes! I made it.. But dont't work..

If you try this with pin interrupt example, does it work?

I will try and write.
The pin mux for JTAG setup only in IOCFG17 register?

I try to revise the following red coded in ProjectZero CC1352P_2_LAUNCHXL.h and I can use SimpleLink Starter App to toggle DIO16/DIO17 without any problem.

...

#define CC1352P_2_LAUNCHXL_DIO16_TDO PIN_UNASSIGNED//IOID_16
#define CC1352P_2_LAUNCHXL_DIO17_TDI PIN_UNASSIGNED//IOID_17
...

#define CC1352P_2_LAUNCHXL_PIN_RLED IOID_16
#define CC1352P_2_LAUNCHXL_PIN_GLED IOID_17

Does it work now?

I can check it late and will write. I think yes.
