Include spi arduino1/13/2024 Serial.println("Ethernet cable is not connected. Now when I run the following init function void Ethernet_Init(void) SPI.begin(HSPI_SCLK, HSPI_MISO, HSPI_MOSI, HSPI_SS) It was SPIClass SPI(VSPI) and i think it is fixed unfortunatlyĪnd I changed here void Enc28J60Network::initSPI() I forced this command SPIClass SPI(HSPI) #define SPI_ETHERNET_SETTINGS SPISettings(spiClk, MSBFIRST, SPI_MODE0)īut still getting not connection with the HW shield… #define CSPASSIVE digitalWrite(csPin, HIGH) #define CSACTIVE digitalWrite(csPin, LOW) Static const int spiClk = 6000000 // 6 MHz Where the variables are the following #define HSPI_MISO 12 PinMatrixOutAttach(HSPI_MOSI, 0, false, false) PinMatrixOutAttach(HSPI_SCLK, 0, false, false) Hspi->begin(HSPI_SCLK, HSPI_MISO, HSPI_MOSI, HSPI_SS) //SCLK, MISO, MOSI, SS I have tried to modify the code in the following way … void New_SPI_init (void) My concern is that If have the following Hw configurationįrom the code it seems that I can only set the CS pin… I need to set all the pins correctly or verify that they are using the right oneĪny idea of what, how or where Can I verify this ? Serial.println("Ethernet cable is not connected.") Įach time it tells that it cannot find the hw… It does not recognize the shield… :(") ĭelay(1) // do nothing, no point running without Ethernet hardware Serial.println("Ethernet shield was not found. Normally this is called after de-asserting the chip select, to allow other libraries to use the SPI bus. inline virtual void endTransaction Stop using the SPI bus. inline void beginTransaction (SPISettings & settings) Initialize the SPI bus using the defined SPISettings. If (Ethernet.hardwareStatus() = EthernetNoHardware) Disable the SPI bus (leaving pin modes unchanged). start the Ethernet connection and the server: Serial.println("Ethernet WebServer Example") Open serial communications and wait for port to open: You can use Ethernet.init(pin) to configure the CS pinĮthernet.init(15) // Most Arduino shields with the IP address and port you want to useīool printWebData = true // set to false for better speed measurement Initialize the Ethernet server library The IP address will be dependent on your local network: Enter a MAC address and IP address for your controller below. read from the file until there's nothing else in it:īeta Was this translation helpful? Give feedback.I just tried one example and It didn’t work, #include if the file didn't open, print an error: MyFile = SD.open("test.txt", FILE_WRITE) so you have to close this one before opening another. note that only one file can be open at a time, Serial1.printf("Debug on UART0 TX GPIO %d and RX GPIO %d\n\r", UART_TX_PIN, UART_RX_PIN) Gpio_set_function(UART_RX_PIN, GPIO_FUNC_UART) Gpio_set_function(UART_TX_PIN, GPIO_FUNC_UART) Using UART 1 as a debug port - serial data is transmitted by the PICO on GPIO 16 Its an input to the chip and can use 3V logic only. Its an input to the chip and can use 3V logic only.ĬS - this is the Chip Select pin, drop it low to start an SPI transaction. SI - this is the Serial In / Microcontroller Out Serial In pin, for data sent from your processor to the SD card. SO - this is the Serial Out / Microcontroller In Serial Out pin, for data sent from the SD card to your processor. If you're using SPI to connect to your SD cards, the pins have the following functions:ĬLK - This is the SPI Clock pin / SCK Serial Clock, its an input to the chip. That means that when the pin's logic level is False there's no card and when it's True there is. This pin is connected to GND internally when there's no card, but when one is inserted it is pulled up to 3V with a 4.7kΩ resistor. Hooking 5V or VBAT to this pin will damage your microSD card.ĭET - Detect whether a microSD card is inserted. MicroSD cards must use 3.3V, so take care to only hook 3.3V to this pin.
