Sowmya, LEDS_LIST and LEDS_NUMBER are defined in the pca10036.h file

Hi Ljyun, Where can we find the definition of LEDS_LIST and declaration of LEDS_NUMBER?

Thank you so much. It helps me a lot. It's my first time to ask question here. So... XD I will do that next time. Thanks both of you again.

One more comment, the OUT register can also be used to write to the GPIO pins. However, it's better to use the *SET and *CLR register because writing to OUT affect all the pins, when with *SET AND *CLR we can choose the pin(s) to modify without touching the others.

The OUTSET and OUTCLR change the values in the OUT register of GPIO. This is a standard pattern repeated all over the nrf51 and nrf52 series, an xxx, an xxxSET and an xxxCLR register to read/write, set and clear bits in the 'xxx' register. this is documented very well in the nRF51 series reference guide.

Please when you post code use the 'post code' button, otherwise the message is very hard to read.
