Read/write to SD card

#1

10-28-2020: Cubecell fails to compile with only one include (SD.H) in the program using a fresh install of Arduino *V1.8.13 and Cubecell board for arduino downloaded last night. It fails on other PC’s as well. This must be an issue with Cellcube. My conversion project to cubecell is dead in the water and this is disappointing. here is the error message that seems to be related to the SPI pin mapping…

Can anyone help? Is there a Heltec support email?

It doeI am working on migrating from Adafruit feather RFM95 board to HTCC-AB01 Development board and am having issues with the arduino SD.H library failing to compile. Is there a special SD.H library for the Cellcube? No examples for DS card are listed in arduino for Cellcube.

The statement it is failing on is…#include <SD.h>
Here is the error messaging…

Maybe my SD.H file is corrupt (it ignored the Tinsy library)

Any help is greatly appreciated.

No "stable" acess to SD card reader?

I think you need to do a migrate with the SPI, the follow example shows how to set SPI

#3

Thank you for your quick reply.

The SPI.h library works fine in the example you provided and in the default SPI.H from arduino. As soon as you add the #include <SD.h> library, it errors out with the same error message. It is like the defines for MISO,MOSI,SCK and SS pins don’t line up with the Cubecell’s assigned pins.
These can be redefined for the SPI port but I do not know what the pin numbers are for the Cubcell to try it (I’m desperate)…
Example
// Map SPI port to ‘new’ pins D14…D17
#define PIN_SPI_SS (17)
#define PIN_SPI_MOSI (16)
#define PIN_SPI_MISO (14)
#define PIN_SPI_SCK (15)

static const uint8_t SS = PIN_SPI_SS;
static const uint8_t MOSI = PIN_SPI_MOSI;
static const uint8_t MISO = PIN_SPI_MISO;
static const uint8_t SCK = PIN_SPI_SCK;

It is late here in Oregon, USA right now (10:46pm) and I am headed to bed now so I may not reply to any comments until tomorrow am.

Thanks again.

Bill

Can you give us the SD card library website URL，we get it and do a fix.

#5

I have no way to link it since it is in the install package from the arduino official website (windows7 and up version). The installer saves the SD.H file in the C:\Program Files (X86)\Arduino\libraries\SD\SRC folder on my HDD.

Here is the contents of the SD.H file…

I signed up for dropbox so I can share the files you are looking for. I think the files that need editing are located in the SD\src\utility folder. The Sd2PinMap.h, and Sd2Card.h look like prime suspects to me.

Here is the link to the SD folder Arduino created and populated on new install…

It is the SPI PIN did not defined in CubeCell variants, I had updated CubeCell variants just now. I can build the sd example now. Please update CubeCell code from git and try again. I hope it works.

#8

I just finished updating and trying it on 3 different PC’s. All three failed to compile. See link below for error listing.

Did try compiling any of the SD examples that are listed in the Arduino Basics? I am using these for testing- all examples fail.

BTW. I bricked my only two Cellcube boards last night by wiring a Neopixel V+ to the 3V3 pin not realizing that it can’t supply the current needed. I have been using the adafruit feather RFM95 board and use the 3V pin and any GPIO pin for control with no issues. I google searched issue and now know that the VEXT pin is what I should have used to power the Neopixel. I still don’t know how to use the VEXT Control pin. The lack of documentation for this board is causing extremely slow development. I will order more boards today but they will not arrive until mid-end of next week.

Here is the link to the error messages after updating the Cubecell board…

I can’t connect to the web you provided.
I compiled the SD examples that are listed in the Arduino Basic

How did you update CubeCell environment？ Now only it is updated in git .
You can replace the folder “variants” in your environment with https://github.com/HelTecAutomation/ASR650x-Arduino/tree/master/variants

#10

That did the trick. Thank you very much!!

The SD examples I tried compiled fine after replacing the files. The manual update process was no fun to do- recommend an update to CubeCell board version from the Arduino boards manager for others to have it a lot easier. I will test the read/write on a SD to be certain all works well when my boards arrive (next couple of days from now).

Hello guys, I am trying to compile the code "CardInfo " of the example on my HTCC-AB02S but I can’t do it. I have tried with other examples and I am getting the same so if You can help me I will much appreciate it. I am getting the following errors:

Hi, I am having the same problem.

I can’t compile any codes. all i am getting errors. Is there any Heltec support email?

Thanks for your help.

Regards.

Hi @BillP,

I am having the same issue as you had but i can’t get it working. i had tried to replace the variants folder as they suggested but still i am having error with the pins. Could you help me too?

I will much appreciate.

Regards,
