Member Function Documentation

DeInit()

static void daisy::Random::DeInit ( )

static

Deinitializes the Peripheral

GetFloat()

static float daisy::Random::GetFloat ( float min = 0.f, float max = 1.f )

static

Returns a floating point value between the specified minimum and maximum. Calls GetValue() internally.

Parameters

min	the minimum value to return, defaults to 0.f
max	the maximum value to return, defaults to 1.f

GetValue()

static uint32_t daisy::Random::GetValue ( )

static

Returns a randomly generated 32-bit number This is done by polling the peripheral, and can block for up to 100ms.

To avoid blocking issues, the IsReady function can be used to check if a value is ready before calling this function.

If there is an issue with the peripheral, or a timeout occurs the return value will be 0.

Returns

a 32-bit random number

Init()

static void daisy::Random::Init ( )

static

Initializes the Peripheral

This is called from System::Init, so the GetValue, and GetFloat functions can be used without the application needing to manually initialize the RNG.

IsReady()

static bool daisy::Random::IsReady ( )

static

Checks the peripheral to see if a new value is ready

Returns

true if conditioning has finished and a new value can be read
