in my pca10001 board,
once i made led pin 18 and 19 pin as internal pull up.
led is not on,and i probe it also but not high.
here my config in blinky example.
NRF_GPIO->PIN_CNF[18] = (GPIO_PIN_CNF_SENSE_Disabled << GPIO_PIN_CNF_SENSE_Pos) | (GPIO_PIN_CNF_DRIVE_S0S1 << GPIO_PIN_CNF_DRIVE_Pos) | (GPIO_PIN_CNF_PULL_Pullup << GPIO_PIN_CNF_PULL_Pos) | (GPIO_PIN_CNF_INPUT_Connect << GPIO_PIN_CNF_INPUT_Pos) | (GPIO_PIN_CNF_DIR_Output << GPIO_PIN_CNF_DIR_Pos);
Kindly tell me ,how to make sw pull up. so led on.
