GPIO_LED_PIN_NUM (6u)

Hi David Guilleman,

Each GPIO instance will have 32 pins and we can use any pin based on our use case. 

In the above case "6u"  means the GPIO pin that is used is pin 6. The suffix  "u"  will indicate that the constant is "unsinged integer".

Ok thanks.

An other question.

What is function of  "GPIO1ModuleClkConfig();" and where is it ?

I found prototype of this function in EVMSK335x.h but nowhere the function

I found this in datasheet and I supposed it's that but I can't find the function in C file in starterware

25.2.2 GPIO Clock and Reset Management
The GPIO modules require two clocks: The de-bounce clock is used for the de-bouncing cells. The
interface clock provided by the peripheral bus (L4 interface) is also the functional clock and is used
through the entire GPIO module (except within the de-bouncing sub-module). It clocks the OCP interface
and the internal logic. For GPIO0 the debounce clock is selected from one of three sources using the
CLKSEL_GPIO0_DBCLK register in the PRCM:

Sorry I post without refresh so thanks for your answer
