Serial check
void setup() { Serial.begin(115200); // Required to flush/empty any cruft/different baud-rate during programming. // while (!Serial) { Serial.println(); delay(10); }; Serial.println("\n\n" __FILE__ "\n" __DATE__ " " __TIME__); } // the loop function runs over and over again forever void loop() { static unsigned long lst = 0; if (millis() - lst > 1000) { lst = millis(); Serial.println("tok"); }; }
i2c scanning
An I2C scan should, at least, find the RFID unit (PN532=0x24) and the i2c expander (MCP=0x20). It may find the screen (typically 0x58 or 0x60) if wired in.
