        g_APinDescription[spiPin].ulPinType,
        g_APinDescription[spiPin].ulPin,
        g_APinDescription[spiPin].ulPinConfiguration);

Exemple #2

Fichier : SPI.cpp Projet : Eih3/v0.83

void SPIClass::end(uint8_t _pin) {
	uint32_t spiPin = BOARD_PIN_TO_SPI_PIN(_pin);
	// Setting the pin as INPUT will disconnect it from SPI peripheral
	pinMode(spiPin, INPUT);
