Edge Detection, Toggle and Range Conversion

Command	Return Value	Description
`Iup(id, input)`	`true` only on the rising edge	Detects each OFF→ON transition once.
`Idown(id, input)`	`true` only on the falling edge	Detects each ON→OFF transition once.
`Ialt(input, state)`	None	Toggles the reference variable `state` at each input rising edge.
`Iscale(x, inMin, inMax, outMin, outMax)`	`int32_t`	Converts an integer range to an integer range.
`Iscalef(x, inMin, inMax, outMin, outMax)`	`float`	Converts a floating-point range to a floating-point range.

bool lamp = false;
void loop() {
  bool button = Ibounce(0, 30);
  Ialt(button, lamp);
  digitalWrite(64, lamp);
}

Command Prototypes

Return Type	Command Prototype
`bool`	`Iup(uint8_t id, bool input)`
`bool`	`Idown(uint8_t id, bool input)`
`void`	`Ialt(bool input, bool &state_var)`
`int32_t`	`Iscale(int32_t x, int32_t in_min, int32_t in_max, int32_t out_min, int32_t out_max)`
`float`	`Iscalef(float x, float in_min, float in_max, float out_min, float out_max)`

Using the same id for different signals may mix their previous states. Do not set the minimum and maximum of the Iscale input range to the same value.
