Hello everyone!
I'm trying to use HSPI (GPIO 12, 13, 14, 15), but I ran into a problem, data is not transmitted and HSPI does not work at all. I tried a simple example, but it doesn't work, no data is transmitted, no clock.
At the same time, the usual BLINK works on these pins. So for some reason SPI is not configured on these pins
Sketch: (leave the backquotes for code formatting)
#include <SPI.h>
#define HSPI_MISO 12
#define HSPI_MOSI 13
#define HSPI_SCLK 14
#define HSPI_SS 15
static const int spiClk = 200000; // 200 KHz
SPIClass * hspi = NULL;
void setup() {
pinMode(13, OUTPUT);
hspi = new SPIClass(HSPI);
//initialise hspi with default pins
//SCLK = 14, MISO = 12, MOSI = 13, SS = 15
hspi->begin();
//set up slave select pins as outputs as the Arduino API
//doesn't handle automatically pulling SS low
pinMode(hspi->pinSS(), OUTPUT); //HSPI SS
}
void loop() {
//use the SPI buses
spiCommand(hspi, 0b11001100);
delay(100);
}
void spiCommand(SPIClass *spi, byte data) {
//use it as you would the regular arduino SPI API
spi->beginTransaction(SPISettings(spiClk, MSBFIRST, SPI_MODE0));
digitalWrite(spi->pinSS(), LOW); //pull SS slow to prep other end for transfer
spi->transfer(data);
digitalWrite(spi->pinSS(), HIGH); //pull ss high to signify end of data transfer
spi->endTransaction();
