Mega 2560, older Adafruit Datalogger PID 1141 Compile Error

[ajohnsonlaird]

EDIT: NOTE, I'M LEAVING THIS POSTING HERE AS A MONUMENT TO MY FOOLISHNESS.
There are TWO SD libraries!
One is in the Sketches folder and the other is (on a Mac) in /Applications/Arduino.app/Contents/Java/libraries/SD

You have two guesses as to which one I replaced. Hint: It was the one in /Applications.
Why?

On web page: https://learn.adafruit.com/adafruit-dat ... d-leonardo
It states:
First, find the "core libraries" folder - if you are using Windows or Linux, it will be in the folder that contains the Arduino executable, look for a libraries folder. Inside you will see an SD folder (inside that will be SD.cpp SD.h etc)

So, silly me....I reasoned that on the Mac I should also look in the folder (aka "Container" in Macspeak) for Arduino.app for a library called SD that has (in a subfolder called src), files SD.cpp, SD.h.
And sure enough those files are there.

Bottom line: On the Mac replace the SD folder in /Sketches/libraries/ and NOT in /Applications/Arduino.app/Contents/Java/libraries/SD.

When you change the correct SD library cardinfo works fine.

---------- ORIGINAL POST-----




I'm trying to use one of the older Adafruit Datalogger shields, Product 1141 on a Mega 2560 R3 with IDE 1.8.19 running on a Mac under Big Sur.
I noted the web page that I had to change out the SD library for the Mega and did that.
I also noted the web page at https://learn.adafruit.com/adafruit-dat ... d-leonardo that provides instructions for the Mega and older Datalogger without the SPI port connection.

I followed the instructions specifically to see if I could get the cardinfo sketch to work. Specifically the instruction that says "The cardinfo sketch uses a lower level library to talk directly to the card, so it calls card.init() instead of SD.begin()." and then shows how to change the line:

Code: Select all

  // we'll use the initialization code from the utility libraries
  // since we're just testing if the card is working!
  while (!card.init(SPI_HALF_SPEED, chipSelect)) {

to read:

Code: Select all

  // we'll use the initialization code from the utility libraries
  // since we're just testing if the card is working!
  while (!card.init(SPI_HALF_SPEED, 10, 11, 12, 13)) {

I have two questions:
Question 1: The first is that in the cardinfo sketch line 50 has an if not a while (but I suspect this is of no great consequece):

Code: Select all

  if (!card.init(SPI_HALF_SPEED, chipSelect)) {

Question 2: When I attempt to compile with the "new" code in place with the 10, 11, 12, 13 pins specified, there's an apparent problem with the Sd2Card class or a subclass, because I get the compile errors shown at the end of this posting -- the invocation signature doesn't match anything in the Sd2Card class/subclasses.

I realize that I may have to go "weed diving®" into the class library, but I reasoned I'm unlikely to be the first person with this problem and/or adafruit might take pity on me!

Anyone figured a workaround for this please? (Be gentle please, I'm an experienced systems programmer but new to Arduino/Mega/SD cards!) :)

Thanks in advance
Andy

This report would have more information with

option enabled in File -> Preferences.

Oh....I forgot to mention that the RTC works fine!

Thanks
