I’m looking to expand the memory on my Photon to store some bulk data. Ideally I’d like to buy a 32GB microSD card, attach to a shield of some sort, and save data I’m gathering from some sensors to the card. I was wondering if anyone’s had success doing something similar? If so, could you walk me th…

I’m working on adding the ability to write to an SD card as part of a code used to log Accel/ gyro data. I tried combining your code with mine, and currently trying to get the two codes to work together by eliminating redundancies

[image] nasib94: #include <SdFat/SdFat.h>; This line suggests you are targeting an old system version and use the legacy version of SdFat library. We'd recommend moving on to the modern structure and more recent system versions.

I am currently using the most recent version of the SDfat library, it is included in my LSM330 code. I checked my SD card using the trymefirst and it is connected properly. However, my code is failing to write my accel data to the SD card. Is there a command I’m missing that allows the photon to wri…

Would someone please provide me with a response.

@nasib94 , a bit more debugging information would be useful. What IS your code able to do? If your take the SD code out of the timers and put it into loop() using millis() delays as timers, does it work there? Sprinkling some Serial.print() debug message would also help to figure what the code is …

my code is able to output the USB data of the LSM330 sensor in addition to publishing the data to the console. I checked my memory card using the “trymefirst” code and the file was written to my SD card correctly. I guess what I am missing is the correct command to write my data to the SD card. The …

@nasib94 , Software Timers have limited stack space. So, why don't you try what I suggested: If your take the SD code out of the timers and put it into loop() using millis() delays as timers, does it work there? Sprinkling some Serial.print() debug message would also help to figure what the code i…

I’m also sampling at 1000 milli seconds right now with no ouput to the SD card. I included ----Serial.print("sd.cardErrorCode(): "); — in order to check for SD error. Attached is my code for reference: // This #include statement was automatically added by the Particle IDE. #include <SdFat.h> //…

If you don’t want people to get lost in that code, you may want to tidy it up a bit before posting. All these comments and scattered declarations don’t make it easy to follow.

#include <SdFat.h> //#include <sd-card-library-photon-compat.h> #include “LSM330.h” #include <Wire.h> LSM330 lsm; void setup(void) { Serial.begin(9600); // The address can be changed making the option of connecting multiple devices lsm.getAddrX_LSM330(LSM330_DEFAULT_ADDRESS_ACCEL); /…

Has anyone had success hooking up an SD card to the Photon and writing/reading data?
