M5StickC (RF) Remote Control decoder

When tinkering with 433 Mhz RF appliance switches it's handy to easily check what codes they respond to. This is a simple decoder using the RCswitch library

 
#include <M5StickC.h>
#include <RCSwitch.h>

RCSwitch mySwitch = RCSwitch();

int x=0;
int y=4; 
void setup() {
   M5.begin();
   M5.Lcd.setRotation(3);
   Serial.begin(115200); 
   mySwitch.enableReceive(0); 

    //labelled G0 on the "HAT" end of the M5StickC 
}

void loop() {
  if (mySwitch.available()) {
   
    Serial.print("Code ");
    Serial.print( mySwitch.getReceivedValue() );
    Serial.print(" / ");
    Serial.print( mySwitch.getReceivedBitlength() );
    Serial.print("bit ");
    Serial.print("Protocol: ");
    Serial.println(mySwitch.getReceivedProtocol() );
    Serial.print( mySwitch.getReceivedValue() );
    Serial.print(",");
    Serial.print( mySwitch.getReceivedBitlength() );
    Serial.print(",");
    Serial.println( mySwitch.getReceivedProtocol() );
 
    M5.Lcd.fillScreen(TFT_BLACK);
    M5.Lcd.setTextColor(TFT_GREEN, TFT_BLACK);   
    M5.Lcd.setCursor(x, y, 2);
    M5.Lcd.setTextSize(1);
    M5.Lcd.print("Code ");
    M5.Lcd.print( String(mySwitch.getReceivedValue()) );
    M5.Lcd.print(" / ");
    M5.Lcd.print( String(mySwitch.getReceivedBitlength()) );
    M5.Lcd.println("bit ");
    M5.Lcd.print("Protocol: ");
    M5.Lcd.println( String(mySwitch.getReceivedProtocol()) );
    mySwitch.resetAvailable();
     
   } //if mySwitch
}//loop
