Just toggle a led on the cc2640.

Netanel Unger

Hi, can you please help me out on this simple task that is extremely tricky on this ARM chip.

1. Global veriables:

const PIN_Config pinLedConstConfig[] = {
PIN_ID(4) | PIN_GPIO_OUTPUT_EN | PIN_PUSHPULL | PIN_GPIO_LOW | PIN_BM_OUTPUT_MODE,
PIN_TERMINATE
};
PIN_Config pinLedConfig = PIN_ID(4) | PIN_GPIO_OUTPUT_EN | PIN_PUSHPULL | PIN_GPIO_LOW | PIN_BM_OUTPUT_MODE;
PIN_State pinLedState;
PIN_Handle pinLedHnadle;

2. Hardware init:

if (PIN_init(pinLedConstConfig) != PIN_SUCCESS)
exceptionHandler(55);

pinLedHnadle = PIN_open(&pinLedState, pinLedConstConfig);

3. on and off

if (PIN_setOutputValue(pinLedHnadle, PIN_ID(4), 0) != PIN_SUCCESS)
exceptionHandler(55);
if (PIN_setOutputValue(pinLedHnadle, PIN_ID(4), 1) != PIN_SUCCESS)
exceptionHandler(55);

No exception raised, port is always on "1" and did not changed, tested with breakpoints on IAR.

Any suggestions?

Try to use the following configuration instead:
const PIN_Config pinLedConstConfig[] = {
PIN_ID(4) | PIN_GPIO_OUTPUT_EN | PIN_PUSHPULL | PIN_GPIO_HIGH,
PIN_TERMINATE
};

Sorry, it did not help.

Hello,
Are you sure you are checking the correct PIN?
You can try to download the BLE-STACK-2-1 and modify one of the examples to verify if it works on your setup.

Hi,

The only example with led control is in the hal_board_cfg and hal_assert.c files, HAL_TURN_OFF_LED1 and HAL_TURN_ON_LED1, unfortunately those macros was not implemented. So i cant even check if the written pin configuration is right and working.

Code comment:

/* Note that only BLE stack accesses LEDs for debug purpose */

It works here.

I modified and added your code to the pinInterrupt example project from the TI-RTOS bundle (you can find the example in CCS resource explorer) and toggles the output value in main and measured with a DMM on DIO4 (i used SmartRF06EB+CC2650EM-7ID where DIO4 will go to RF1.11-LCD_MODE on jumper P403 on the SmartRF06EB). I remove the if tests and the call to exceptionHandler.

It works!

I just got an defective board with pins that did not soldered properly.

Thanks you all, and sorry for the waste of time.
