Relay - Initialization

This page contains the first steps when starting with programing the LED matrix breakout board.

Initialization

To use the LED matrix board, first, include the required library, create the LED matrix object and define CLK_PIN, DATA_PIN, CS_PIN and MAX_DEVICES (it represents the number of daisychained boards, in this example, it will be 1),

#include "Led-Matrix-SOLDERED.h"
#include <SPI.h>


#define HARDWARE_TYPE Led_Matrix::PAROLA_HW
#define MAX_DEVICES   3
#define CLK_PIN       18 // or SCK
#define DATA_PIN      23 // or MOSI
#define CS_PIN        4 // or LOAD

Led_Matrix mx = Led_Matrix(HARDWARE_TYPE, CS_PIN, MAX_DEVICES);

void setup() {
  // put your setup code here, to run once:
  mx.begin();
}

//...

Led_Matrix mx = Led_Matrix()

Creates matrix object

Returns value: none

Function parameters:

Type	Name	Description
`moduleType_t`	`mod`	Sets the mode in which module will be working
`uint8_t`	`csPin`	Digital pin number for data communication
`uint8_t`	`numDevices`	Sets the number of daisy chained modules

Initialization​

Led_Matrix mx = Led_Matrix()
