#include <M5StickC.h>
#include <Wire.h>

#define CARDKB_ADDR 0x5F

void setup()
{
  M5.begin();
  Serial.begin(115200);
  Wire.begin();
  M5.Lcd.fillScreen(BLACK);
  M5.Lcd.setRotation(3);
  M5.Lcd.setCursor(1, 10);
  M5.Lcd.setTextColor(YELLOW);
  M5.Lcd.setTextSize(2);
  M5.Lcd.printf("IIC Address: 0x5F\n");
  M5.Lcd.printf(">>");
}
void loop()
{
  Wire.requestFrom(CARDKB_ADDR, 1);
  while(Wire.available())
  {
    char c = Wire.read(); // receive a byte as characterif
    if (c != 0)
    {
      M5.Lcd.printf("%c", c);
      Serial.println(c, HEX);
     // M5.Speaker.beep();
    }
  }
  // delay(10);
}

Try this for the M5stickC could work, ...

#include <M5StickC.h>
#include <Arduino.h>
#include <ESP8266SAM.h>  //https://github.com/earlephilhower/ESP8266SAM
#include <AudioOutputI2S.h>  //https://github.com/earlephilhower/ESP8266Audio

AudioOutputI2S *out = NULL;

void setup()
{ 
  out = new AudioOutputI2S(0, 1, 32);
  out->begin();
}

void loop()
{
  ESP8266SAM *sam = new ESP8266SAM;
  sam->Say(out, "Can you hear me now?");
  delay(500);
  sam->Say(out, "I can't hear you!");
  delete sam;
}

This works on the M5stack, for the stickC I cannot test tho..

#include <M5Stack.h>
#include <M5StackUpdater.h>
#include <Arduino.h>
#include <ESP8266SAM.h>  //https://github.com/earlephilhower/ESP8266SAM
#include <AudioOutputI2S.h>  //https://github.com/earlephilhower/ESP8266Audio

AudioOutputI2S *out = NULL;

void setup()
{
  M5.begin();
  Wire.begin();
  if(digitalRead(BUTTON_A_PIN) == 0){
    Serial.println("Will load menu binary");
    updateFromFS(SD);
    ESP.restart();
  }  
  out = new AudioOutputI2S(0, 1, 32);
  out->begin();
}

void loop()
{
  ESP8266SAM *sam = new ESP8266SAM;
  sam->Say(out, "Can you hear me now?");
  delay(500);
  sam->Say(out, "I can't hear you!");
  delete sam;
}

@andreaf said in How to change LCD print text on runtime without creating another line:

M5.Lcd.print("some text")

M5.Lcd.setCursor(xposition , yposition);
M5.Lcd.print("some text")

or ;

M5.Lcd.drawString("some text"), xposition , yposition , txtsize);

get a proto and build the 15 pins female port in it..

Proto stack

@ajb2k3

@ajb2k3 Its not uiflow, its makecode (for micro-bit) and arduino for m5

@world101 ok, thx
