Hello, i am having trouble uploading a code to Core2, trying to connect a CardKB module.
Does anyone know how to fix it?
#include "Wire.h"
#include "Arduino.h"
#include "M5GFX.h"
#include "M5Unified.h"
#define CARDKB_ADDR 0x5F
int x=10,y=10;
M5GFX display;
M5Canvas canvas(&display);
void setup()
{
auto cfg = M5.config();
M5.begin(cfg);
Serial.begin(115200);
Wire.begin();
pinMode(5, INPUT);
digitalWrite(5, HIGH);
M5.Lcd.fillScreen(YELLOW);
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)
{
if(c==180){
//M5.clear();
//x=x-10;
M5.Lcd.fillCircle(50, 50, 22, TFT_RED);
}
if(c==181){
//M5.Display.clear();
y=y-10;
M5.Lcd.fillCircle(100, 50, 22, TFT_BLUE);
}
if(c==182){
//M5.Display.clear();
y=y+10;
M5.Lcd.fillCircle(50, 100 , 22, TFT_YELLOW);
}
if(c==183){
M5.Display.setCursor(0,0);
//M5.Lcd.fillScreen(WHITE);
delay(1000);
M5.update();
x=x+10;
M5.Lcd.fillCircle(100, 100, 22, TFT_GREEN);
}
//M5.Lcd.printf("%c", c);
//Serial.println(c, HEX);
// M5.Speaker.beep();
}
}
}
