InitializeGPIO

Initializes GPIO

void InitializeGPIO(void);

---

GetPin

Gets pin value as a boolean

tBoolean GetPin(tPin pin);

Parameters:

• pin The pin being checked

Returns:

• The boolean value of given pin

---

SetPin

Sets pin value as a boolean

void SetPin(tPin pin, tBoolean val);

Parameters:

• pin The pin being set
• val The boolean value the pin is being set to

---

SetPinZ

Sets a pin into high impedance mode

void SetPinZ(tPin pin);

Parameters:

• pin The pin being set to high impedance mode

---

PullUpPin

Adds a weak pull up resistor to the pin

void PullUpPin(tPin pin);

Parameters:

• pin The pin getting a weak pull up resistor

---

PullDownPin

Adds a weak pull down resistor to the pin

void PullDownPin(tPin pin);

Parameters:

• pin The pin getting a weak pull down resistor

---

CallOnPin

Registers a callback to be called when the pin's value changes, the state of the

void CallOnPin(tCallback callback, void *data, tPin pin);

Parameters:

• callback Pointer to a function that will be called whenever the pin changes
• data Pointer that will be sent as an argument to the callback everytime it
• pin Pin being listened to
