Hi everyone
I want to share my recent weekend Arduino Project where I connect the powerfull Mikrotik RouterBoard to the Arduino using the USB native port on Mikrotik. My idea was enable the LCD module in the Mikrotik and them received data in Arduino and pass it to an LCD HD44780 using an I2C Bus.
Here is the code I used to accomplish the task.

#include <SoftwareSerial.h>
#include <Wire.h>
#include <LiquidCrystal_I2C.h>
LiquidCrystal_I2C lcd(0x20,20,4); // set the LCD address to 0x20 for a 16 chars and 2 line display
SoftwareSerial mikrotik(10, 11); // RX, TX
bool validDataFound = false;
char buffer[100];
void setup()
{
Serial.begin(9600);
mikrotik.begin(9600);
lcd.init();
lcd.backlight();
writeLcd("Reading Mikrotik");
}
void loop()
{
storeData();
writeLcd(buffer);
}
void writeLcd(char * name)
{
lcd.clear();
lcd.setCursor(1,0);//Collum 1, Row 0
lcd.print("Arduino + Mikrotik");
lcd.setCursor(3,1);//Collum 3, Row 1
lcd.print("Mikrotik name:");
lcd.setCursor(3,2);//Collum 3, Row 2
lcd.print(name);
}
void findMarker()
{
byte tester;
while(1)
{
if(mikrotik.available()>0)
{
tester = mikrotik.read();
Serial.write(tester);
}
if(tester == 0x3A)break; //Means de marker : has been found
}
}
void storeData()
{
uint8_t i =0;
byte temp;
buffer[0] = '\0';
findMarker();
while(1)
{
if(mikrotik.available()>0)
{
temp = mikrotik.read();
if(temp != 0x20 )
{
//Insert the byte on the char array
validDataFound = true;
buffer[i++] = temp;
buffer[i] = '\0';
}
if(validDataFound == true && temp == 0x20)
{
validDataFound = false;
break;
}
}
}
Serial.println(buffer);
}
Here is the final result.Nothing particular remarkable just a raining weekend in Portugal
