Timestamp issue with Hypnos

[garysekhon09]

Having issues with the timestamp while logging data with SD using Hypnos. I tried to reset it by taking the coin cell battery out but it still not synching with the current time.

define _dout A0 //MISO

define _sclk A1 //SCK

define _pdwn A2 //A2

define sdPin 11 // Change to 11 if using HypnosV3.3

define alarmPin 12 // Hypnos interrupt pin

include "ADS1232.h"

include "RTClib.h"

include

const float startingWeight = 815.00; // Known weight to divide by in grams int unit = 0; // Units: {0 = grams, 1 = kilograms, 2 = ounces} char buff[] = "Start time is hh:mm:ss DDD, DD MMM YYYY";

int packet = 0; // Packet number

void do_calibration() { long t_new_offset = 0; long t_raw_read = 0; float t_set_scale_value = 0; float t_weight = 0;

// reset to default values weight.OFFSET = 0; weight.SCALE = 1.0;

// tare t_new_offset = weight.raw_read(100); // Takes 8 measurements and averages it weight.OFFSET = t_new_offset; Serial.print("Calibration offset = ");Serial.println(weight.OFFSET); Serial.println("You have 15 seconds to put a known weight on the scale"); delay(15000);

// do calibration based on a known weight t_raw_read = weight.raw_read(3); Serial.print("Units read = ");Serial.println(t_raw_read); t_set_scale_value = t_raw_read / startingWeight; // divide it to a known weight weight.SCALE = t_set_scale_value; Serial.print("Calibration scale value = ");Serial.println(weight.SCALE);
