Pins int1 and int2

#1

Hi,
In the rephone pinout it labels the six pins on the right: gnd, int1, int2, vcc, SCL and SDA. Could int1, int2, SCL and SDA be used as GPIO?

#2

Hi bobbiy,

yes the int1,int2 SCL and SDA can be used as GPIOs.

Please refer to the following schematic:

For more info about the module schematics you can find at resources of Xadow GSM+BLE

#3

How could I use these pins in the arduino IDE? If I upload the blink sketch with pin 13 it doesn’t work.

#4

Hi Bobbiy,

check the topic I just posted. Access the GPIO Pins based on Different IDEs

#5

Thanks! I’ve got int2, SDA and SCL working with the blink sketch. But int1 isn’t working for some reason. I tried the blink sketch with the pin number 0 and E1 but they both don’t work.

OK, here is an example which I just tested based on Arduino IDE for RePhone Kit. Make Sure your firmware is updated to the Arduino IDE for RePhone Version

[code]#define PIN_INT1 E2 //GPIO18
#define PIN_INT2 E1 //GPIO13
#define PIN_SCL 6 //GPIO43
#define PIN_SDA 7 //GPIO44

void setup()
{
pinMode(PIN_INT1, OUTPUT);
pinMode(PIN_INT2, OUTPUT);
pinMode(PIN_SCL, OUTPUT);
pinMode(PIN_SDA, OUTPUT);
}

void loop()
{
digitalWrite(PIN_INT1, HIGH);
digitalWrite(PIN_INT2, LOW);
digitalWrite(PIN_SCL, HIGH);
digitalWrite(PIN_SDA, LOW);
delay(1000);
digitalWrite(PIN_INT1, LOW);
digitalWrite(PIN_INT2, HIGH);
digitalWrite(PIN_SCL, LOW);
digitalWrite(PIN_SDA, HIGH);
delay(1000);
