Hello everyone.

I can't understand, what is the problem.

When I use predefined function  GPIO_togglePin(DEVICE_GPIO_PIN_LED2); the pin toggles, however if I use the register directly, like GpioDataRegs.GPBTOGGLE.bit.GPIO34 = 1; - nothing happens

    Hi,

    You should be able to open the definition of GPIO_togglePin function and check if there is any additional step in the function which you are missing while accessing direct write to GPIO register. Quick thing to check is the pin mapping (GPIO_PIN_LED2 is GPIO34).
