/ Program to demonstrate the MD_Parola library
//
// Uses the Arduino Print Class extension with various output types
//
// MD_MAX72XX library can be found at GitHub - MajicDesigns/MD_MAX72XX: LED Matrix Library
//
#include <MD_Parola.h>
#include <MD_MAX72xx.h>
#include <SPI.h>
const uint16_t WAIT_TIME = 1000;
// Define the number of devices we have in the chain and the hardware interface
// NOTE: These pin numbers will probably not work with your hardware and may
// need to be adapted
#define HARDWARE_TYPE MD_MAX72XX::PAROLA_HW
#define MAX_DEVICES 4
#define CLK_PIN 13
#define DATA_PIN 11
#define CS_PIN 10
// Hardware SPI connection
MD_Parola P = MD_Parola(HARDWARE_TYPE, CS_PIN, MAX_DEVICES);
// Arbitrary output pins
// MD_Parola P = MD_Parola(HARDWARE_TYPE, DATA_PIN, CLK_PIN, CS_PIN, MAX_DEVICES);
void setup(void)
{
P.begin();
}
void loop(void)
{
P.print("Hello");
delay(WAIT_TIME);
P.print(1234, DEC);
delay(WAIT_TIME);
P.print(1234, HEX);
delay(WAIT_TIME);
P.print(12.5); // float not supported by Arduino Print class
delay(WAIT_TIME);
P.print(9876l);
delay(WAIT_TIME);
P.println("end"); // only get the /r/n characters - avoid using println
delay(WAIT_TIME);
P.write('A');
delay(WAIT_TIME);
P.write('B');
delay(WAIT_TIME);
P.write('C');
delay(WAIT_TIME);
}
I got this problem:
exit status 1
'PAROLA_HW' is not a member of 'MD_MAX72XX'
