このプログラムは、入力を読み取り、Arduinoのシリアルモニターに書き出すことを目的としています。シリアルモニターに1文字しか書き込まないという問題。
void setup()
{
Serial.begin(9600); //Set the serial monitor.
lcd.begin(16, 2); //Set the LCD
}
// Alignment variables
boolean left = true; //Set boolean left to true to begin to display text in middle of screen.
boolean right = false; //Other possible align booleans set to false
boolean select = false;
//Text show/hide variables
boolean show1 = true; //Both values set to true to display on start up.
boolean show2 = true;
//Serial input
char serialinput [4] = {0}; //For 3 value input, and null character to end.
char line1;
void loop()
{
if (Serial.available() > 0) { //If the serial monitor is open it will read a value.
line1 = Serial.read();
Serial.print(line1);
memmove (serialinput, &serialinput[1], 3); //copy the value to memory
serialinput [2] = Serial.read(); //value is read.
//if statements for each possible input.
}
