Attiny84 DS3231 Error

rahulsathya · July 12, 2021, 1:07am

Hi, I'm a beginner to Arduino and currently am using Arduino as ISP to program my Attiny84. I'm using DS3231 as an interrupt for certain intervals. Initially, I tried everything successfully interfacing Arduino and DS3231 without Attiny. When I replaced Attiny instead Arduino, I came to know that Wire.h library doesn't support with Attiny. So I searched online and started using the TinyWireM.h library. Since am a noob, am unable to understand the error codes. I have attached my code below and commented my error in the comments. Kindly help me with this.

#include <TinyWireM.h>
#include <ds3231.h>

//#define Wire TinyWireM

volatile boolean interruptActive = false;

int pinLed1 = 7;
int pinLed2 = 0;
int interruptPin = 8;

struct ts t;

uint8_t wake_HOUR;
uint8_t wake_MINUTE;
uint8_t wake_SECOND;

void gotoSleep(void);

 void flash(int pinLed) {
  digitalWrite(pinLed, HIGH);   // turn the LED on (HIGH is the voltage level)
  delay(200);                       // wait for a second
  digitalWrite(pinLed, LOW);    // turn the LED off by making the voltage LOW
  delay(200);   
 }
 
void setup() {
//  Serial.begin(9600);
  pinMode(pinLed1, OUTPUT);
  pinMode(pinLed2, OUTPUT);
  pinMode(interruptPin, INPUT_PULLUP);
  
  TinyWireM.begin();
  DS3231_init(DS3231_CONTROL_INTCN);
  flash(pinLed1);
  flash(pinLed2);

//   attachInterrupt(0, wake, FALLING);
   attachInterrupt(8, wake, FALLING);
  //Disable ADC - don't forget to flip back after waking up if using ADC in your application ADCSRA |= (1 << 7);
  ADCSRA &= ~(1 << 7);

}
 
void loop() {
  // put your main code here, to run repeatedly:
  DS3231_get(&t);

 if (interruptActive) {
  digitalWrite(pinLed1, HIGH);   // turn the LED on (HIGH is the voltage level)
  for (int i = 0;i < 10;i++) {
     flash(pinLed2);
  }
   digitalWrite(pinLed1, LOW);   // turn the LED on (HIGH is the voltage level)

  delay(1000);
 }
 interruptActive = false;
  gotoSleep();
}

When you made your original program I assume you worked from examples to learn how to use wire.h, correct?
Have you checked examples for TinyWireM.h to be sure that you are using it correctly?
I am not sure about this case, but not every library can be directly swapped out. In fact that is the exception rather than the norm.

This points up to the previous line in your compiler output to tell you the specific line of code that is in error.

C:\Program Files\WindowsApps\ArduinoLLC.ArduinoIDE_1.8.49.0_x86__mdqgnx93n4wtt\hardware\arduino\avr\libraries\Wire\src\utility\twi.c:88:16: note: each undeclared identifier is reported only once for each function it appears in

You can see from the path in the error messages that the standard Wire library is still being used, not the TinyWireM library.

rahulsathya · July 12, 2021, 7:24am

Yup I even saw that but I don't know how to make it call the tinywire library
