Hi. I am currently using this library for a proyect. I have an SD card where a file called config.csv is present. Each file's row represents a change in the configuration of the program. I had no problems with the file, but when i added the RTClib and used the rtc.begin() function, the csv parser started to have incorrect lectures of the file. Does this mean that i can't use both libraries together? Why does this happen? Here is the code, ignore the first part where i define variables.

` // Código complementario para incorporar la lectura del archivo de configuracion programado // Our idea is having a file present in the SD card called config.csv where each row is a programmed change of variables // Any row's first field is either a 0 if the row was already loaded or a 1 if wasn't loaded, the second is the moment where that configuration should take place, the rest of the fields are all the variables to be changed. // Those variables are in the same order as showed in the MainProyect file, in the section "Variables Parametrizables" ("lastWatered" is not present in the config)

// Each field occupies a fixed amount of characters, so we know exactly how long each row is.

define ROW_LENGTH 57 // Fixed length of each row, counting the EOL characters

}

// We only want to overwrite the first character. myFile.print("0"); }

void checkConfig(){ if (cp.readSDfile("/config.CSV")) { uint8_t notLoaded = (uint8_t)cp["loaded"]; uint32_t configTime = (uint32_t)cp["cTime"]; uint32_t SDwateringTime = (uint32_t)cp["wTime"]; uint32_t SDwateringInterval = (uint32_t)cp["watInt"]; uint16_t SDsoilHumLim = (uint16_t)cp["soilLim"]; uint8_t SDambHumLim = (uint8_t)cp["ambLim"]; uint8_t SDstartWateringAt = (uint8_t)cp["sW"]; uint8_t SDendWateringAt = (uint8_t)cp["eW"]; uint8_t SDlightsON = (uint8_t)cp["lON"]; uint8_t SDlightsOFF = (uint8_t)cp["lOFF"]; for (int row = 0; row <= cp.getRowsCount(); row++) { //if(notLoaded[row] == 1) { Serial.print(row); Serial.print(" , "); Serial.println(SDstartWateringAt[row]); delay(500);

  if (notLoaded[row] == 1) { // (rtc.now().unixtime() > configTime[row])
    deleteLine(row);
  }
}

} else { Serial.println("Error"); } } ` And this is the csv file config.csv

When i call the method cp.print(), this is what appears in the serial: Header: loaded | cTime | wTime | watInt | soilLim | ambLim | sW | eW | lON | lOFF Types: uint8_t | uint32_t | uint32_t | uint32_t | uint16_t | uint8_t | uint8_t | uint8_t | uint8_t | uint8_t Values: 0 | 1357971456 | 1111111111 | 1357971456 | 1111 | 111 | 11 | 11 | 11 | 11 0 | 117637459 | 1111111111 | 117637459 | 1111 | 111 | 11 | 11 | 11 | 11 0 | 524292 | 1111111111 | 524292 | 1111 | 111 | 11 | 11 | 11 | 11 0 | 327880 | 1111111111 | 327880 | 1111 | 111 | 11 | 11 | 11 | 11 0 | 4 | 1111111111 | 4 | 1111 | 111 | 11 | 11 | 11 | 11

The "cTime", and "watInt" columns should be all 1's, but instead those values appears. This is a problem that doesn't appear when instead i run the same program without the rtc.begin() and rtc.lostPower() methods.
